Smelting Tungsten

The man took Alex behind the smithy, to a place that was quite separate from all others.

"Where are we going?" Alex asked.

"The furnace for melting this metal is over there in those buildings. You can't just melt it anywhere you want because of how much heat it produces," the man said.

"I see," Alex said. He looked around the snow-filled backyard of the smithy and saw quite a few people working on parts of artifacts that didn't require much physical work. 

The basic furnace-related work was done in the front shop.

They arrived at a location from where Alex could feel intense heat without even entering any of the rooms. "The furnace is here?" Alex asked.

"Yes," the man said. "Scared? I'm not returning your ores even if you want to quit now."

"Oh, it's fine. I don't plan on quitting so easily," Alex said and waited for the man to open the door.
