For the next entry in our series on Tools of the Trade we’ll look at the jewellery torch.
A jeweller’s torch is a key tool for any metalsmith or bench jeweller who works on creating and repairing jewellery. They are specifically designed for soldering and working with precious metals. A torch is an essential part of our work – they get used in our workshops on a daily basis.
How a Jewellery Torch Works
The fuel used for torches could be propane, acetylene, butane or natural gas. The different gases are used under different circumstances depending on the type of metal being worked and the setup of the workshop.
Whichever gas is being used is typically combined with oxygen to create a hotter, more powerful flame. This is why you can see that there are two lines leading into the torch and two knobs to control the flow of each. One is for the oxygen, and the other is for the gas.
The flames that are produced are hot enough to melt silver (melting point = 962°C), gold (1064°C) – even platinum (1768°C)!
