Wow, heat resistant sandals and invisible safety glasses.
That explains why we don't manufacture in Aus any more.
I didn't realise the oil made the sand like concrete.
OK, I was VERY wrong, reading the comments it's not oil they use. I'm more familiar with green sand casting which uses oil to compress and hold the sand together.
I've played with small brass castings (rough) using plaster for a mould and a bit of aluminium when younger but haven't done any sand casting.
I wouldn't want the job of tipping absolutely every bit of steel scrap they could find into the furnace. It didn't look particularly safe.
