You can&rsquo;t just blast it. If you do, you&rsquo;re asking for internal stress and cracks the second you start scoring. The secret isn&rsquo;t the total wattage—it&rsquo;s about where that heat actually goes.</p> <h2 id="shaping-the-heat">Shaping the Heat</h2> <p>Most heaters just give you a flat, uniform spread of heat. That works for basic stuff, but if you&rsquo;re in R&amp;D or messing around with new materials, it&rsquo;s just not enough. We do things differently. We map out the power density across the heater to create specific &ldquo;hot zones.&rdquo; By tweaking the winding density or how the voltage drops across certain sections, we can pinpoint exactly where the glass hits its transition temperature. It gives you the freedom to play around. You can test how different thermal gradients change the way your material fractures without guessing.</p>
