No <a href="https://goldisgood.com">major</a> drop, no obvious crack, just a sudden shatter during a routine temperature shift. It&rsquo;s frustrating. And usually, it happens because the glass has &ldquo;frozen-in&rdquo; tension. Basically, if the glass cools too fast or unevenly during manufacturing, it stays stressed. It&rsquo;s like a coiled spring waiting for one tiny bump to let go. We fix this with infrared (IR) heating that stays steady within 0.1°C.</p>
