Installation notes

  1. 1Heavy blocks, handle with rated lifting equipment and protect cast faces
  2. 2Use zircon-based or AZS-compatible bedding mortar at joints
  3. 3Plan controlled furnace heat-up; AZS exudes glassy phase (exudation) on first heat, design joints for it
  4. 4Select VF (void-free) grade where glass quality (stone/blister-free) is critical
