Maborite (MgO) Anti-sticking Powder on Trays / Hearths

● Prevents cupels from sticking to hearth
● Increases Tray / Refractory Lining life

Maborite has same composition as cupels
● So Maborite absorbs and retains litharge

● Limits litharge attack to electric elements
● Emissions of noxious PbO vapours notably reduced.

Move many cupels / blocks at once, easing manipulation while keeping rank order. Two parallel wide grooves under Tray allow flat fork (TF) prongs inlet.

Trays also protect furnace hearth from litharge (PbO) spills.

Always spread Maborite powder on tray top to absorb PbO spills.

Maborite prevents cupels from sticking to Tray and increases Tray life. Litharge attack is stopped and emissions of noxious PbO vapours notably reduced.
