Fimo clay can be baked on glass or aluminium baking trays but can also be formed around glass objects; such as votive candle holders, glass tiles, vases and other decorative items. Whether you are baking fimo clay items onto glass or you are just using a glass pan to bake items, you need to follow the proper process to achieve the best final result for your fimo projects.
Hand-form your fimo clay into whatever shape you like. If you are covering a glass item with the clay, form the fimo clay around the item, pinching it tightly over rims and lips on vases, glasses or candle holders. This will keep the baked clay on the glass.
Preheat a conventional oven to 129 degrees Celsius and place your finished fimo pieces onto an aluminium or oven-safe glass baking dish.
Bake the clay pieces for 20 minutes and allow them to cool for another 20 minutes. Check the clay's hardness and continue baking for 10 more minutes if needed.
Embed glass, wooden or metallic beads into the surface of the fimo clay in a decorative pattern.
