No, and neither can any other cutting method. Tempered glass is heat-treated to create internal stress that makes it stronger, but that same stress means cutting it causes it to shatter into small pieces immediately. This is true for waterjet, laser, saw, or any other process—it’s a property of the glass itself, not a limitation of the cutting method. If your project requires tempered glass in a custom shape, the glass must be cut to shape first, then tempered afterward. That’s standard across the industry. For non-tempered glass types—annealed, laminated, low-iron, mirrors, specialty glass—we handle them all without issue.
