Sterling Forge

My son wants to make his own class ring he a blacksmith?

He got a knife in sterling silver butter and nickel silver and white hot in the forge and it would not melt. After 3 hours of continuous white heat (2500 degrees), it would still not melted. What can he do? All metal workers from there?

regular money is fairly inexpensive. Just go to the quarter prior to 1964, dimes, half dollars. 1964, is only 90% of money so I would do a few years earlier. You can find old coins fight for real cheap at almost any which store coins. They usually have a box of them on the counter. He could probably even use foreign coins as they are silver. They should have some too. I have made the method of lost wax casting. What does he want?
