Our crucibles
The seller of 5L crucible claims "Ze zijn geschikt voor het smelten van metaal tot 1100°C". Silicium Carbide ( SiC) crucibles all over the internet are all rated up to 1500-1600 °C. No reason to believe that ours is any different. As the seller is a art supply store, I suspect this is a non-techie way of saying "Use only for non-ferrous metals". If you are serious about melting cast iron or steel, you probably know what you are doing anyway ;)
How to use crucibles
- Liquid metal is seriously dangerous. Do not YOLO this, it will hurt you.
- Melting Aluminium? No, soda cans are NOT a good source of aluminium.
- They may contain residual moisture, and can explode when dipped in molten metal.
- They are covered in paint and coatings, and create a LOT of slag.
- Do not pack/jam solid metal into the crucible! As it heats it will expand, and can crack the crucible.
- After pouring metal, *always completely* empty the crucible! Clean out as much slag as possible.
- Keep dry, only store back into the samla when completely cooled off
