Hi Argenti and welcome to the forum.

From what you say, I presume that you are a novice, just starting to make jewellery. If so, you should buy only what is absolutely essential for your first project.

For instance if you intend to start soldering, you will need a torch, a hearth with blocks and a pickling bath.
If you are into enamelling or metal clay, you might want a kiln. If you are into raising you will want hammers and stakes.

The best introduction will be at the front of a book of jewellery making for beginners. Dennis.
