It usually happens because of internal stress. If you cool a vessel too quickly or hit it with uneven heat, it’s basically a ticking time bomb. That&rsquo;s why we use infrared (IR) heating for annealing. It lets us hit that perfect transition temperature without guessing.</p> <h2 id="why-chasing-01c-actually-matters">Why chasing 0.1°C actually matters</h2> <p>Glass is picky. There is a very narrow window where the <a href="https://goldisgood.com">stress</a> disappears. If your heater swings by just a few degrees, you&rsquo;re back to square one, creating new thermal gradients. We keep our IR elements stable within 0.1°C. Why? Because we want the glass to relax, but we don&rsquo;t want it to actually <em>melt</em> or sag. It&rsquo;s a delicate balance. We&rsquo;re just giving the silicate structure a chance to settle in. Plus, shortwave IR is great because it doesn&rsquo;t just sit on the surface. It sinks deep into the glass wall. This means the core and the skin hit the target temperature at the same time. No more &ldquo;skin effect&rdquo; where the outside looks fine but the inside is still screaming under tension.</p>
