The Nature of Plasticine: Why It Can’t Be Baked

The nature of plasticine is fundamentally different from bakeable clays, which is why it can’t be baked. Plasticine is an oil-based modeling compound that’s designed to remain pliable indefinitely. This unique characteristic makes it ideal for certain applications, but it also means that attempting to bake it will result in a melted mess rather than a hardened sculpture.

Composition of Plasticine

Plasticine’s composition is the key reason why it can’t be baked. This modeling clay is typically made from a mixture of:

Calcium salts (such as calcium carbonate)
Petroleum jelly
Long-chain aliphatic acids (stearic acid)
Oils (mineral oil)

This combination of ingredients gives plasticine its distinctive properties:

Malleability: The oils and petroleum jelly keep the clay soft and workable.
Non-drying: Unlike water-based clays, plasticine doesn’t dry out when exposed to air.
Reusability: It can be reshaped and reused multiple times without losing its properties.

What Happens When You Try to Bake Plasticine?

When exposed to heat, plasticine doesn’t solidify like polymer clay. Instead, it undergoes a series of unfortunate transformations:

Melting: The oils in the plasticine begin to liquefy, causing the clay to lose its shape.
Oozing: As the temperature rises, the melted plasticine can seep out of its original form.
Fume Release: The heating process may cause the release of potentially harmful fumes.
Fire Hazard: In extreme cases, the oils in plasticine could potentially ignite, creating a fire risk.

“Attempting to bake plasticine is not only ineffective but can also be dangerous. The oils can separate and potentially catch fire, posing a serious safety hazard in your kitchen.” – Sarah Johnson, Craft Safety Expert

These reactions occur because plasticine’s melting point is much lower than the temperature required to harden bakeable clays. According to The Blue Bottle Tree, when you assume you have polymer clay but instead have plasticine and bake it in the oven, it will melt, with the oil oozing out of the clay.

Plasticine vs. Polymer Clay: Understanding the Difference
