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 However, the truth is that the clay softener should only be applied when the clay is out of date.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.
