At a glance
- 1 kg capacity — sized for daily retail buy-back and small casting work
- Induction heating reaches pouring temperature in minutes, not tens of minutes
- Set-and-hold temperature control protects karat alloys from overheating
- Runs on a single-phase supply and air cooling — no three-phase install, no water circuit
- Standard crucible size, so replacements are easy to source locally
About the Vortex Vulcan
The Vortex Vulcan — also written Vulcan furnace, or the Vortex Vulcan melting furnace — is sized for the shop that melts every day but rarely melts large. A 1 kg graphite crucible takes buy-back jewellery, casting sprues and bench scrap, and an induction coil brings the charge to pouring temperature in minutes rather than the twenty a resistance furnace would need.
Because induction heats the metal itself, the charge spends less time hot. That means less oxidation, less zinc burned out of karat alloys, and a composition that still matches what you weighed in. The stirring effect of the field mixes added copper and silver evenly, so an alloy comes out consistent rather than layered.
Temperature is set and held rather than judged by eye, and the unit runs on single-phase supply with air cooling — no water circuit to maintain, and no three-phase installation to arrange before it can be switched on.

Vortex Vulcan — questions
Is 1 kg enough capacity for a retail shop?
For most retail counters, yes. A 1 kg furnace comfortably covers customer buy-backs, bench scrap and small casting. Move up a size only if you routinely melt more than a kilogram in a single session.
Does it need three-phase power?
No. The Vortex Vulcan runs on a standard single-phase supply. Tell us the voltage and frequency at your premises when you order and the unit is configured for it; fit a stabiliser sized to the rated draw if your supply dips under load.
Can it melt silver as well as gold?
Yes, along with karat alloys and copper. Keep a separate crucible per metal so contamination is not carried between melts.
What does a replacement crucible cost?
The Vortex Vulcan uses a standard 1 kg graphite crucible, currently $45. Keep a spare on the shelf so a cracked one never costs you a working day.
