You score the sheet, you hope for the best, and then you pray you don&rsquo;t see those jagged micro-cracks or a messy corner breakout when you finally make the break. It&rsquo;s frustrating, and it wastes material. That&rsquo;s why we use infrared (IR) preheating. We get the glass warm before the blade even touches it.</p> <h2 id="why-the-heat-matters">Why the heat matters</h2> <p>Think of it as relaxing the material. IR lamps don&rsquo;t just warm the surface; they get deep into the glass and shake up the molecular structure. This lowers the internal tension and makes the glass a bit more &ldquo;giving.&rdquo; When you score preheated glass, the crack actually behaves. It follows a <a href="https://henruite.com">straight</a> line instead of jumping around erratically. The result? A crisp, clean break every time.</p>
