Pure copper is one of the most commonly used base metals for kiln-fired enamel work.

In humid or outdoor environments, it may eventually develop a green patina (verdigris). To preserve the bright copper finish, apply a clear lacquer or wax coating after cleaning. For indoor decorative use, untreated copper develops an attractive aged appearance naturally.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eCan I cut or drill these discs to a custom shape?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes. Pure copper cuts cleanly with tin snips (thinner gauges), a jigsaw with a metal blade, or an angle grinder with a cutting disc. Drilling is straightforward with standard HSS drill bits — use cutting oil and moderate speed to avoid work-hardening. For precise circles or holes, a hole saw or step drill bit works well.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eAre these discs compatible with soldering and brazing?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes. Pure copper accepts both soft solder (tin-lead or lead-free) and silver brazing alloys readily. Clean the surface with flux before soldering. For torch brazing, use a silver-bearing brazing rod with appropriate flux. Copper's high thermal conductivity means you may need a larger torch tip or longer heat-up time for thicker discs (2.0mm+).\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow many pieces do I get per order?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003ePack quantity varies by variant — options include 1 Pcs, 2 Pcs, 3 Pcs, and 5 Pcs.
