Glass annealing schedule
WebAnnealing allows the glass to stabilize and adds strength to your finished project. • Ideal annealing temperatures are 900° F for 90 COE and 950° F for 96 COE glass. • 30 minutes is usually sufficient for small projects but you may choose longer annealing times for larger pieces. • When in doubt, anneal longer; you cannot over anneal.
