We finally found the right factory for the decals. These are underglaze decals made from cobalt oxide and maybe manganese to make the color darker in some cases. They wet the oxide down until it is a slip-ish consistency and smeer it into a steel mold type thing. The mold has a very thin carving design of the decal on it. Once the oxide is pressed in and excess is scraped away a piece of thin paper like tracing paper is placed over it and pressed onto the top of the mold with a large roller. Then the paper is peeled away with the oxide design on it. All you have to do in order to transfer it to a pot is apply it just like a temporary tattoo with water. These things are pretty cool and super cheap so I bought a few sheets with dragons and things on them so I can make china gifts for people when I get home.
