This was our first level 2 class that pigged backed off the information we learned in the intro pendant making class. The focus here was learning about encasing opals in glass and using them in pendants.
This followed the same process as making pendants. The initial pendant glass used this time was a follow borocilicate glass. The end was sealed then heated so the tube slowly filled up with liquid glass. The opal was then dropped in carefully and the glass heated and rotated to prevent air bubbles forming in the tip of the pendant. A contrasting color was added to the back of the pendants to better show off the opal.
This was the handout provided in the class. It gives a quick background on Gilson opals and describes the embedding process with some neat pictures.
Gilson opals are commercially available at Profound Glassworks (http://www.profoundglass.com/store/pc/viewCategories.asp?idCategory=2) and where the class supply was from.
