It’s frustrating. One minute everything looks fine, and the next, you&rsquo;ve got a pile of shards. It usually <a href="https://o-yate.com">comes</a> down to internal stress. If the outside of the glass is screaming hot while the core is still shivering, the material just gives up and fractures.</p> <h2 id="the-trap-of-standard-heating">The trap of &ldquo;standard&rdquo; heating</h2> <p>Here is the thing: most off-the-shelf lamps just blast heat evenly across the board. That sounds like a good thing, right? Wrong. Real-world glass isn&rsquo;t a perfect, thin sheet. You&rsquo;re dealing with thick walls and weird geometries. When you use a generic heater, the edges overheat while the center stays cold. We see this all the time in labs.
