Salt Cake / Spent Flux Salt cake · Dross · Dross

What to check before you buy
- Metal content %: For dross and residues, metal content sets the value. Agree the testing method and the lab, and settle the rate on the agreed result.
- Dimensions / tolerance: Write down the size and the allowed variation, for example thickness, width, diameter or length with plus and minus limits, and agree how they will be measured.
- Moisture / oil: Wet or oily scrap and turnings lose weight on melting and are a safety risk in the furnace. Agree a limit and whether material must be dried or de-oiled.
- Packing: Agree how material is bundled, strapped, palletised or wrapped, and how it is protected from moisture and damage in transit. Poor packing is a common cause of claims.
- Lot check: Ask whether it is white or black dross, the typical metal content, size and how it was cooled and stored. Agree how metal content will be tested and how handling and transport will be done safely, since dross can react with moisture.
