I recently took a Foil class at Kathy Wilcox's studio. She had a guest demonstration by the wonderful Chris Hierholzer. This was the first torch firing of enamels that I have seen. His application and sgraffito of the foil was great to watch. He has a nice article on foil and torch firing on Patsy Croft's website: http://alohilanidesigns.com/working-with-foils/

Here are some photos of his demonstration at Kathy's:

He is setting the gold foil with Klyr Fire

He is fusing the foil to the base enamels

He is sgraffito'ing the foil

This is the piece - sgraffito complete and ready for final firing with clear enamel on top

Final firing...watch the progression of the enamel

Here you could stop the firing and have a "druzy" effect to the jewel

Bringing it to a glossy sheen

Thank you Chris! Thank you Kathy for sharing him with your students :)

Pam - Great photos ...

Enjoyed being in class/meeting you.

Looking forward to more adventures...

Pam-

The progression photos of the final firing are impressive.  Couldn't get those with a kiln firing!
