Getting Your IR Lamps to Actually “Talk” to Your Glass

If you’ve spent any time with glass art or scientific blowing, you know that additives are everything. They give you the colors you want, the right refractive index, or that specific thermal expansion you need for a project to actually work. But here’s the catch: those additives are picky. They don’t just soak up heat however they feel like. If your IR lamp is pumping out wavelengths that your glass simply ignores, you’re just wasting electricity. Worse, you end up with uneven heating, which is a one-way ticket to thermal shock and a shattered piece of work.
