Polymer Clay Castle

Polymer Clay Baking Tips

I am attempting to make a castle model at 1 inch = 10 foot scale out of Fimo (it was on sale so I chose it over Sculpey).

I was thinking of using a base of 1/16th inch plastic sheet and use it for floors etc. with walls of clay.

Can the plastic parts go in the oven with the Fimo? Or do I have to come up with something else?

(The reason for the plastic is so I can make use of the inside of the castle, not just have the castle walls.

I need it as a reference.

It depends on what type of plastic you buy. For example, 1/16th inch styrene will soften between 290 and 340 degrees F. That would be fine since polymer clay is baked at 275 degrees F.

If you buy some other type of plastic sheeting or are not sure what type it is, you can do a test by running a small piece through your dishwasher.

Don’t use your oven to test because if the plastic has a low flame point and, if it starts to burn, the fumes can be pretty noxious and potentially deadly.

You didn’t mention how you plan to finish your plastic castle floors, but do you know that you can apply a polymer clay veneer to plastic?

If you veneer both sides (completely sealing the plastic), there is no question that it will hold. However if you want to veneer only the top surface, do a test.

Polymer clay does not adhere to some surfaces, for example glass.

If the clay does not stick when baked onto one side, you can still use a single layer veneer. Simply apply it with adhesive.

E6000 cement and gel cyanoacrylate adhesives like Krazy Glue or Superglue work well with polymer clay. The thick gel is better because it fills in any gaps or unevenness.
