What tool is required to cut Cellular Glass?

• A. Chisel
• B. Hacksaw Blade
• C. Hammer
• D. Pocket knife

Answer: (B)

Cutting cellular glass requires a tool that can make a clean, straight cut without causing chipping in its brittle, closed-cell structure. A hacksaw blade provides the right balance of rigidity and fine teeth to slice through the material smoothly along the chosen line. The fine teeth reduce the chance of tearing and edge damage, giving you a neat kerf. Other tools like a chisel tend to gouge and crush the edges, a hammer can’t cut, and a pocket knife isn’t strong enough to handle the material's hardness and thickness. For best results, use the hacksaw blade in a frame, clamp the piece, and guide the cut slowly along your line.
