I recently ordered an ebook by Lena Beckeus, who has been experimenting with glass powders on fiber paper. If your work includes fusing glass, I highly recommend this. Here is a link to purchasing her book:
She started a group on Facebook for those who purchase her book as a place to show their new work and learn more from her and others. It's really fun seeing everyone's pieces.
I finally had to try it myself ... although I won't be showing the FB group my pieces yet! I have a limited supply of glass powders, so I tried a couple I had. I like two of the three pieces I made and will slump them in molds next. They are very simple. The top piece is a 6" square and the bottom is 4" x 10". Isn't it interesting how the powder separates into puddles?! Am I going to order a few more new colors? You know I will ...
