Can you melt silver with a butane torch?
You’ll need a brick and a blowtorch. We use butane to refill the torch (sold in supermarkets refills for lighters or torches). In the case of silver jewelry debris to melt to make a nugget, just make a small pile with silver debris in the middle of the brick, then heat with the torch.
What can I use to melt silver in?
Secure a furnace or a blow torch. The furnace or torch is what you’ll be using to heat your silver to its melting point. As such, the furnace or blow torch are critical items in melting silver. Depending on the amount of melting you’ll be doing, you can choose between a furnace or torch.
What does borax do when melting silver?
There are two purposes in adding borax to molten silver. First, the borax melts and forms a glassy layer over the molten metal, protecting it from oxidization. Second, metal oxides are highly soluble in molten glass, so the molten borax removes any oxides that are already there.
Is it illegal to melt silver coins?
It is legal to melt silver or gold coins in the US. The reason behind this decision is most likely to do with there not being any silver or gold coins in circulation.

Called collectible or numismatic coins, these are coins collectors will pay extra for due to their rarity or age. Melting them down would be a waste of money.
What torch will melt silver?
A propane torch such as a Sievert can put out a fair amount of heat – certainly enough for casting ingots, although it’s better in a brazing hearth to keep the heat contained. The Sievert has bee a long time favourite with the jewellery trade and more recently the EZtorch, which has an adjustable air intake.

What is a crucible for silver?
Fire Assaying Crucibles are mainly used for smelting gold ore concentrates and black sands when using a flux. These crucibles provide a cost effective solution when refining these materials. They are a great choice for torch and kiln jewelry casting, or melting gold, silver, copper, and other metals.
Can gold melt?
Gold melts at 1940 F, so the process of melting the metal entails applying intense heat to change the chemical and physical composition. You will also need to eliminate impurities and coalesce fine gold particles before melting your metal to ensure the best outcome.

Can you melt silver without flux?
Boric acid in a well borax glazed container can remove the metal oxides from the silver/metal without affecting its purity. Mix the borax and soda, pour it into the crucible while the silver is torched. Keep torching the silver/metal until the borax melts it, and then pour it into the mold.
