This is an opaque vitreous glass enamel powder, ideal for torch or kiln fired enamels on copper or silver. 

This is a deep opaque blue, and one of our most popular deep blues in class. It is reliable and stable when fired. Our sample colour in the image was fired on a copper test disc. 

This enamel fires at temperatures from760°–815 °C on fine silver and copper as well as  fired fine-silver metal clay. 

How hot is that you ask?

If you are using a torch to fire your enamel pieces, you can judge the appropriate level of heat and time in the flame by when the enamel becomes glossy.

Experimentation is required, as well as practice, to understand how your individual torch works. Whether you use a torch or a kiln, firing times will depend on the metal, as well as the size and weight of the piece. 

Torch Firing notes: This colour will exhibit grey oxides if it is hit directly with the flame. 

Sold in a sample pot size (approximately 3 grams, perfect to test the colour or for little projects) or medium pot (approximately 10 grams).

The medium pots are better if you are a regular enamelist and want to have this basic material on hand for all your needs.
