What is the best way to melt natural Wolframite?
Just droplet steel into 1k2 C wolframite is better since droplet wont turnback into solid at that point, and vacuum room is much easier for dupe to travel into and pump those wolframite out than spend the whole day reconstruct the room to corner build tungsten. Please show me how to melt tungsten using steam room first.
