Hello all.
First post here, so please be kind.

I was talking to someone recently about lost wax casting and they asked what temperature is needed to melt brass and silver. I said between 900 and 1000 Celsius.
They then asked why a torch is used when a kiln can get that hot?
So question is, with a lost wax, could the metal be placed in the sprue, the whole thing put in a kiln so the metal melts and drips into the cavity?

Don't know the answer so just asking.
