This is a solder pot solder with a great amount of silver base solder metal  (£100+) to cast your miniature and jewellery.

The kit comes also with flux and clamping board to hold your mould close when pouring as well as a small stainless steel ledle.

I've been making moulds from 3D print and then pouring the metal in the rubber mould to achieve copies in metal... But no longer have the time and space for this.
