I was at the Nelson-Atkins museum of art the other day and I saw a piece of Chinese pottery from the 16th century. The color was as bright and as vivid as a piece of 1970's Pyrex.

I also thought to myself, hey, that's a pretty good cyan.

Fuji has a photoceramic process called 'Fuji Photoceram' as seen here.

I'm interested in ways that photographs can be made in ceramics and thus made highly permament. If that can be applied to color... well shoot, I'm a happy camper.

What really defines a photoceramic process??

Are there genuine methods of producing photographs in ceramics, or is it usually just the application of some other kind of image forming layer atop it? (like applying an emulsion, or a carbon transfer, etc.)
