Things to Know When Using Polymer Clay

Polymer clay is not a pleasant type of clay for those who are familiar with sliced or lightweight clay. And the sincere advice is to test it properly and not follow the reckless instructions of the seller.

Is polymer clay hardened, does it expire?

Polymer clay is harder than air dry clay. Most before use, users never go through the condition to soften the clay. There are many ways such as using rolling pin or rolling machine to roll the clay until it is soft or using the hands to roll the clay. The temperature in the process will soften the clay. Or simply, you can use clay softener. However, the truth is that the clay softener should only be applied when the clay is out of date.

How to store polymer clay?

Do not think polymer clay is not dry clay in the air, so no need to store. You should use a zip-lock bag to remove the opened clay and add some baby oil.

Does the house have an oven, can it be microwave or boiled or steamed with clay?

  • With the microwave: my advice is NEVER. You just try, and you will see the black clay and full of smoke.
  • Slow / boil: Each clay brand usually has a certain baking temperature requirement. Kato is 150 degrees. Premo and Scupley are 130 degrees. Fimo is 110 degrees. And if you learn chemistry, you know, water boils at 100 degrees. Is it 100 degrees to ripen when the required temperature is at least 110 degrees?.

But you should also try, when your products are small 5cm or less and not too thick.

Instead of buying multiple colors, can I buy white and blend in?

  • Mixing with acrylic color/oil color: Acrylic oil and oil color will dry the clay. Not to mention that when you bake, the heat causes the oil in the color to burn. Only use acrylic to cover the surface when the clay has finished baking.
  • Food color mixing: can use. But it will take a lot of color to dye the clay. And you cannot use the boiling method.
  • Use chalk pastel: can be used. You should apply a matte or gloss coating before baking.

After baking, cracks appear on the product?

90% is the temperature is not right & enough. The oven depends on the brand and after a period of use the temperature will no longer be accurate. Therefore, it will usually take longer than the temperature & time noted on the package.

How to Choose a Suitable Polymer Clay Brand

There are many brands of polymer clay. So which one is best? Actually, there is no correct answer. Depending on your purpose, you will select each suitable brand. Here is some basic information about some popular brands for your reference.

Original Sculpey

Its clay is only white and Tera. The clay is the softest. It is also the cheapest, which is suitable for mock-ups, sculptures or designs that need work with paint or spray paint. However, Original Sculpey is not a good choice when making large products that need good support because the finished product is very fragile. Overall, its products are suitable for children.

Sculpey III

Soft and easy to mold by hand or clay gun. The clay has many different colors, blends easily, but is quite soft and brittle after baking, especially with thin products. Therefore, Sculpey III is more suitable for display products than for jewelry. Its products are also difficult to use when making clay cane.

Super Sculpey

Products of this brand are beige and human skin. Easily molded and firm after baking. Suitable for making large items like statues, dolls, or pedestals for other products during baking. However, you need to use cornstarch to prevent soil contact.

Sculpey Ultralight

This clay is extremely soft and easy to knead, but becomes very hard after baking. Only white, but you can paint it with acrylic or spray it after baking.

Premo! Sculpey and Premo! Accents

Premo! Sculpey and Premo! Accents are softer than Fimo Classic, but harder than Sculpey III. Premo is quite flexible when baked, which makes it difficult to break even with thin pieces. Accents line contains mica powder so the color has a sparkle or metallic luster. And Premo colors often come with familiar names like Aquamarine or Red Cadmium.

Fimo Soft & Fimo Effect

Its properties are very similar to those of Sculpey III. It has many colors and high softness. This type of soil maintains its strength and elasticity after baking.

Fimo Classic

Fimo Classic is quite hard, so it keeps the shape and color you want. Therefore, it is suitable for making clay cane.

Kato

Kato is the hardest of all polymer clay, but it also has the strongest durability after baking. The best way to soften it is rolling with a rolling mill or roller. Kato is less colorful than other types, but the colors are perfect for valuable artwork.

Pardo

This is a rare brand. Colors due to mica powder should be more sparkling than the same color of other brands. Especially the clearest colors. Soft and often more expensive than other types.

Clay Court in Tennis: What Are The Differences?

Let’s learn a bit about the basic structure of a clay court in the traditional structure with natural materials and ClayTech clay court.

The first is traditional clay courts in France and Italy with almost 100% natural materials. Specifically, the basic structure of these pitches is as follows:

  • The lowest layer is gravel and small stone for quick drainage, if the outdoor yard is invested a lot of money, right under the rock and gravel there is a drainage system.
  • Next is the material taken from iron ore: waste materials of iron ore.
  • Next is a hard lime layer with about 5 – 7cm thick.
  • Top layer: People use a mixture of fine clay mixed with brick to blend in a certain formula to form a layer of flour and this layer of flour is evenly spread on the ground.

It is the top 2 layers that make a big difference to the clay court which makes the ball bounce high but slow. We can see the difference between Madrid Master 2012 and Rome Master 2012. The clay ground in Rome Master bounces higher and slower than the Madrid Master 2012 yard. The steps of running or bouncing down the red dust flying very clearly. The surface of the upcoming Roland Garros is the same standard and structure as the Rome Master.

ClayTech ground

The yard at Madrid Master is a hard plastic surface and converted into clay court using ClayTech technique. The basic structure of Clay Tech clay court includes:

  • The bottom layer of ClayTech clay ground is a mixture of concrete mixed with synthetic resin such as the common Hard Court yard.
  • Next is a layer of glue.
  • The top layer is called ClayTech: ClayTech consists of a buffer layer with Synthetic – polypropylene material and covered on top is a special powder mixture. It is no longer pure clay mixed with ground bricks, but replaced by a layer of industrial clay powder that has properties similar to clay mixed with ground bricks. And this layer of flour and the bounce of the ball faster makes Nadal, Djokovic and other players complain about the pitch at the Madrid Master recently.

Types of Clay Used in Handmade

Extremely popular clay in life from modeling clay for young children to handmade clay. Clay makes it easy to shape and blend colors to satisfy your imagination. If you want to try making some DIY items from clay, let’s read this article carefully.

Clay is a soft and flexible substance when it is moist so it is easy to shape. The clay will become solid when dry and become a solid when heated at high temperatures. So clay is very useful in the craft field. From different types of clay will produce different types of materials when baked in different conditions such as ceramic, porcelain or earthenware. Basic clay is mainly white, gray, red depending on the compound in clay.

In the field of handmade we mainly have 3 basic types based on their properties including polymer, air dry and non-dry clay.

Air dry clay: Dry after molding with normal ambient temperature. Use art creation. High price. Originated from Japan and spread to countries like Korea, Thailand, Malaysia, etc. Air-dry clay is mainly white. After shaping by hand, the clay will be dry and hard when exposed to air. This clay does not tolerate water even with resin. This clay is colored with acrylic or mixed with oil paint.

Polymer Clay: Use an oven or water bath. Made from synthetic plastic polyvinylchloride polymer. Easy to create images by hand. Good adhesion, durability and beautiful. Use heat (can use an oven with appropriate temperature & time or water bath) to heat polymer clay. Due to its extreme durability & long shelf life, it is suitable for making jewelry, dolls, models, etc. However, this clay cannot be rolled like dry clay. There is also a type of thin clay to cover the surface or stick to the product.

Non-dry clay: Colorful, soft, easy to form, fragrant and reusable many times should be used as modeling clay for children.

Handmade products from handmade clay are extremely diverse such as chibi / dolls, earth flower paintings, mini food, keychains, earth flowers, jewelry, accessories, etc.

Ethnic People Use Clay to Make Hair and Makeup

The strange hairstyles made of clay have created a characteristic for the ancient Himba tribe in Namibia.

Perhaps the Himba tribe in Namibia is a unique tribe left in the world with very special customs. Over many generations, Himba’s semi-nomadic tribe still lives as primitive despite the development of the world of outsiders to an unbelievable level of science and technology.

Instead of using cosmetics, they make Otjize, a red substance, used to apply to skin and hair. Women here do not wear bras, women only wear a loincloth to cover the lower body, the rest are still bare even when meeting strangers.

Himba people are also known by other names as Omuhimba people or Ovahimba people living mainly in western Kaokoland, in northern Namibia. Because of living in one of the harshest areas of the planet, their water resources are extremely scarce. That’s why the Himba people have never bathed all their lives. The use of bath water is a trance in the tribe.

Instead, they use Otjize to clean and protect the skin from the sun. The substance is red soil, derived from fat. Himba people apply Otjize to the whole body, then use medicinal powder in combination with other herbs and then burn it to burst. This is their “bath” way. Otjize has the meaning to represent the earth, blood and the beauty of the tribe is still about 50,000 members.

From puberty, Himba women began to braid their hair into strands, each day, they spent about a few hours to take care of their hair, take clay and red soil to apply it to their hair in order to maintain a perfect shape.

Photographer Franco Cappellari, 61, from Venafro recounted his experience in the same tribe. Women are extremely conscious of beauty and spend a lot of time on their looks. Although there are still a few children still wearing T-shirts, the Himba tribe are hardly Westernized. The government of Namibia has specific policies to protect Himba from external impacts.

NASA Discovered A Large Aamount of Clay Minerals on Mars

Robot discovered Curiosity of the National Aeronautics and Space Administration (NASA) recently discovered the largest amount of clay minerals since the robot was put on Mars in August 2012.

Curiosity was launched on Mars from Earth in November 2011 and spent more than half a year net to land on the planet in August 2012. The Curiosity probe is equipped with 17 cameras, weighs about 900 kg and can reach a maximum speed of 3.8cm / sec. When operating on the surface of Mars, Curiosity undertakes the search for evidence of microorganisms while collecting data and images of Mars. The preparation for Curiosity’s mission lasts for two years and costs about $ 2 billion.

According to a new NASA announcement, two specimens that Curiosity found when drilling two rock targets were named Aberlady and Kilmarie. These specimens contained the highest amount of clay ever discovered in NASA’s mission. Both of these drilling goals were discovered when Curiosity took a new selfie on May 12. The area of high clay content is located on the side of the low area in Mount Sharp. This region was originally outside of NASA’s discovery trajectory before Curiosity was brought to Mars in 2012.

Apart from that, Curiosity is currently working on the discovery of Sharrp Mountain (5500 meters high) to see if the area has conditions to support life billions of years ago. Therefore, the new discovery plays an important role in this task because clay is often formed in water, an essential chemical compound for life. Curiosity’s mineralogical analysis tool, CheMin, brought to Earth the first analysis of the drilling samples in the area of much clay.

In addition, during this drill and analysis, Curiosity uses a black and white navigation camera to capture clouds drifting on May 7 and May 12. These clouds may be ice clouds (containing water), about 31km from the Martian surface.

Mysterious Civilizations Attached to Clay

Below are the mysterious civilizations with traces left made of clay.

Norte Chico civilization

The Norte Chico civilization (3,500 BC – 1,800 BC – BC), also known as Caral civilization or Caral-Supe, contains many mysteries. Originally this was the Chico settlement located north of the capital Lima (Peru) today.

The most impressive achievement of Norte Chico civilization is the massive architecture and weaving. Especially the pyramids and complex irrigation systems make Norte Chico become a place with developed agriculture and capable of self-sufficiency. Today, in this land, there are many massive ancient works, including pyramids and the rest of the complex irrigation systems. So far, six pyramids have been discovered in Peru, including the largest pyramid called Piramide Mayor. There is no evidence that the Norte Chico people were involved in war or conflict. Settlements centered around the three major rivers should cause the destruction of this civilization to be assumed to be due to prolonged droughts that have caused the population to die or migrate.

Nineveh civilization

The Nineveh civilization (6,000 – 612 BC) was one of the oldest and greatest civilizations in the world. King Sennacherib (704 – 681 BC) decided to take Nineveh as the capital of the Assyrian Empire, building a large wall with 15 surrounding gates and other works such as parks, canals, bridges and a palace. Some scholars believe that the famous Hanging Gardens of Babylon in Nineveh were built by this king.

In addition to the above architectures, there is a huge library in Nineveh, containing more than 30,000 clay tablets depicting patterns and data. Scholars and scholars rushed here to make Nineveh a center of art, science and architecture of the Middle East at that time. One of the most unusual articles found here is similar in content to Noah’s Ark (Noah’s boat), the Book of Genesis in the Bible.

Vinca civilization

Vinca civilization (5,000 – 3,500 BC) is the world’s earliest written civilization, with about 700 characters, most of which are found in the form of carvings on pottery. Vinca’s farming system makes it one of the most developed Neolithic cultures that people have ever known. The first archaeological evidence was discovered in 1908 at Belo Brdo hill near Belgrade. Settlements are believed to have existed for more than 1,000 years before being abandoned. Each of these settlements contained several thousand people living in houses made of clay and mud mixed with straw.

Is The Clay Statue in Italy The Final Work of Leonardo Da Vinci?

Leonardo Da Vinci is a painter, sculptor and inventor, famous works and handed down through history. In 1519, he died at the age of 67, leaving many regrets. Recently, art managers in Italy suspect a strange sculpture is the last surviving work of Leonardo Da Vinci.

The Virgin with the Laughing Child has long been considered a sculpture by an Italian artist named Antoni Rossellino. The Virgin with the Laughing Child is a sculptured statue kept in London’s Victoria & Albert Museum since 1858 and recorded under the name Antonio Rossellino. The material of this statue is red clay. However, recent art researchers suspect that Leonardo Da Vinci was the creator of it in 1472. At the Master of Leonardo exhibition at Palazzo Strozzi in Florence (Italy), the curators showed the work and revealed that this is the only surviving sculpture of Leonardo Da Vinci. He used red clay to make it when he was a student of Andrea Del Verrocchio.

This sculpture being exhibited in Leonardo Da Vinci’s masterpiece exhibition takes place at Strozzi Palace in Florence, Italy, until July. A 20-inch high suspicious sculpture made of earth red lightning. It describes the Virgin Mary looking down at the baby Jesus.

Managers and scholars have said that the main feature of the artwork is similar to Leonardo Da Vinci’s drawing. They argue based on the posture of the legs of the Virgin Mary and her mother’s eyes to see that Jesus is similar to the other works of this master’s painting. Perhaps Leonardo Da Vinci created this work in his twenties with fish looking clear and full of love, especially motherhood.

Scholar Francesco Caglioti, a lecturer at the University of Naples in Italy, is a leader in the study of Leonardo Da Vinci’s sculptures. He said art historian John Pope-Hennessy said the sculpture was by the artist Antoni  Rossellino. He often attributed artwork to his own will without clear evidence. However, John Pope-Hennessy died in 1994, so he was unable to give any controversy about the question.

5 Benefits of Playing with Clay for Your Children

Clay is considered one of the handmade toys that parents should let their children play. Clay is used in many education systems around the world. Thanks to the variety of colors, this toy can help your baby develop a comprehensive brain. Here are the great benefits that clay brings to your child.

1. Development of hand force

Any young child needs to develop hand force, especially his hand part so that he can easily get used to activities like writing, playing instruments or drawing. When playing with clay, children will have the opportunity to practice hand force through kneading, squeezing, rolling, cutting and pinching to create shapes through their memory or imagination.

2. Develop creativity

There is no doubt that one of the main benefits of playing with clay is helping children develop their creativity and imagination. Your child can mold a dog or a car. This demonstrates the ability to comprehend the shapes of things around your child’s life.

3. Help children express emotions

Clay can only be shaped when children use their hand force. Therefore, this will be a toy to help children relieve their emotions quite well. Children who are bored, upset or happy can be shown on clay, which is due to the modeling principle of this toy. There are many parents who let their children play with clay to help them relieve their emotions very effectively.

4. Developing senses

Sensory development is very important for all young children while clay can do it. In terms of touch, children will be familiar with the flexibility, adhesion, smoothness or softness when playing with different clay. In terms of smell, parents can create scents corresponding to each different color so that children can automatically relate to all familiar things around. For example, yellow smells of lemon, pink smells of flower or orange smells of orange.

5. Learn and play effectively

These types of modeling clay are accompanied by shapes such as round, triangle, rectangle, star and more. They will help children to be familiar with all shapes and colors reflected in each object in daily living space.

When Can Your Kids Play with Clay?

Clay is one of the most favorite toys for our children. Clay can be found in preschools, book stores or entertainment areas. However, not every age can play clay. It has been proven that the most suitable age for playing clay is from 3 years and up.

One of the benefits of playing clay is that you will be creative with your imagination through molding different objects. This also motivates personality to be developed in a positive way, such as compressing and flattening clay that will help the child relieve psychology when angry or suppressed. In addition, you can let your child play clay modeling as a gentle punishment if they are not good. However, like any toy, clay still has some potential risks. Therefore, you should not give them a set of clay until they are 3 years old. Here are some reasons adults should only play clay when they are 3 years old and older.

Reduce the desire to taste strange things

When your baby is 3 years or older, your child will be less interested in learning everything by putting things in their hands into their mouths. Because the taste of the child is now fully developed and helps him or her realize that clay is not delicious at all.

Understand what parents say and become more obedient

Children only knew their parents did not allow this or that. But when he was 3 years old, he will understand many of his parents’ commands and explanations.

Motivate children to developing their creativity

Children under 3 years of age often only watch clay as a powder. They are less interested in playing with this powder than with other attractive toys. But when 3 years old, children will learn how to utilize clay to make objects with their shapes and favorite colors.

3-year-old children who can play clay do not mean that you can let them play alone without adult supervision. Because unexpected accidents such as swallowing foreign bodies are still possible for children in this age group. Therefore, you should not be subjective.
