Tikigodz, you're hitting all the tiki arts Painting, carving, ceramics,...

Ceramic clay cannot be cured in the oven. It will only become brittle and very fragile. There are several oven bake clays but I don't think any are suitable for food contact. I'll tell Wendy (Danlovestiki) about your question, she works with SuperSculpty and maybe she'll have an answer.

Those are nice looking sculpts TikiGodz, but someone else will have to advise you on the molds - I'm not much of a mold maker. The problem is not in the amount of detail but in the undercuts and deciding how many pieces the mold will need to be.

If you are slip casting, I think people use plaster molds.
So they don't need to be fired in a kiln.

What the world needs now are more master mold makers. When I make a mug in sculpey and then paint it with acrylic paint it's for display only. I've never made a mold. VanTiki makes each one by hand and fires them in a kiln, never two exactly alike. He doesn't need a mold or to worry about undercuts. Wendy

If you want to cast resin, then you need a flexible mold.
Silicone and Urethane are most common, but not inexpensive.
Latex is cheap, but takes a long time to make and breaks
down pretty quick in production.

And don't forget to check on youtube.
Just about anything you want to learn is on there.

A two piece mold is most common, but complex shapes may require
several pieces, to allow you to be able to get the part out of the mold.

Another trick, you might be able to hand work the pieces
after they come out of the mold, to add subtle details.

Plaster molds degrade with use, their detail becomes worn down,
parting lines more noticeable, etc, and they need to be replaced.
