Does anyone have any idea on how the color variation/movement in the green glaze is created? It is a premade glaze from my local pottery shop, and the employees were unable to tell me how it is done. I have a basic ingredients list, but it does not give specifics on the type of feldspar or frits used. Any help would be appreciated, as I'm new to glaze making. Thank you!
Here is a link to the basic ingredients sheet. The glaze is called Metallic Green, under the HG (high gloss) section.
