Baking sculpy on top of fiberglass?


Well-Known Member
Second fiberglass question of the week! If I had a fiberglass mask and wanted to add a little organic detail with sculpy, would the mask be able to withstand the low cooking temp needed to cure they clay?

I searched with google and couldn't get a good answer. Thank you!

i know that with resin props you can bend them if you put them in hot water so i guess it could warp your piece....and you dont know what kind of gases might get released in the oven.

I'd be leery of putting the fiberglass in the oven, deforming being on of the reasons. What about using a heat gun to bake the sculpey?

Use Aves Apoxie Sculpt instead. It's a self-hardening, strong, resin that works remarkably similar to super sculpey when mixed. Super Sculpey is brittle and will break off.

Fiberglass shouldn't warp under the low heat needed for Sculpey, but then I would never put fiberglass or Sculpey in my home oven that I cook my food in.

In other words, yes you can do it, but there are better materials out there (epoxy) for what you want to do.
