All the glass I use is lead free, food safe and made in Oregon. I use different techniques and make most of my own molds. Raking is one of the more dangerous techniques I use. It involves layering glass in the kiln and firing it 400 degrees hotter than regular fusing. When the glass has melted all together I then open the kiln and manipulate the molten glass. It is dangerous and time-consuming, but worth the results. Find out more online at http://www.artthoujuliet.com.
