Our refractoiry Cupel trays application is to quickly handle cupels or bullion blocks while keeping their rank order.
Beneath their surface, our cupel trays have two parallel wide grooves to easily and safely handke them with Tray Forks.
Furthermore, cupel trays are also useful to protect the furnace hearth against Litharge (PbO) spills.
Our Cupel Trays are made of silico aluminous refractories that give them a long life. This material and their design also protects them against the conitunous cooling and heating cycles they endure.
However, we recommend spreading Maborite on top of the tray to absorb Litharge spills. Maborite also protects the cupels from sticking to the tray and further protects the furnace hearth from Litharge attacks.
Our range of cupel trays covers the major part of furnace sizes.
