It’s frustrating. Usually, it happens because of &ldquo;cold spots&rdquo; during annealing. When you&rsquo;ve got weird shapes and tight angles, some parts of the glass just don&rsquo;t get the heat they need. That creates internal stress, and eventually, the piece gives up. To fix this, we use long-life infrared heating tubes. Instead of just hoping the air gets hot enough, <a href="https://henruite.com">these</a> tubes push high-density radiant heat directly into the glass, wrapping around those irregular shapes to make sure every single inch hits the right soak temperature.</p>
