Let’s Talk About Glass Annealing Bulbs

If you’ve ever had a piece of glass shatter for no apparent reason, you know the frustration. Usually, it’s internal stress. That’s where our annealing bulbs come in. Their whole job is to get that stress out without shocking the glass into a million pieces. We use high-purity quartz for these. Why? Because the infrared heat needs to actually “sink in” to the borosilicate or quartz you’re working with. If the heat hits unevenly, you’re just waiting for a crack to happen.
