Just got back from doing a demo at Odyssey for Master's of the Mountains. It is a really interested group and some wanted more on this skull series I am working on.
I sculpted a human from a real skull, then I made a mold so I could either slip cast or press mold it. I usually press mold it as I don't make that many. Then I add parts like Zygomatic bones and work on extracting teeth. Then cut the skull cap and put in a flange for a lidded skull or just turn the cap for a skull cap incense burner.
I will then put on white slip or a crackle slip and rub in some oxides and fire. Then I will see if it is realistic and add more oxides or stains and refire until it is right. I am working on glazing some and then sandblasting.
