GPK DELUXE KK-8 KIT
PROPANE FIRED MODULAR KWIK KILN 8 - 8" ROUND x 11" TALL
Smelt Ore Concentrates, Melt Pure Metals, Fire Assay...
Do it all in the new KK8!
Included is a custom USA built precision machined bi-metal brass tipped Propane Burner, 6' hose, needle valve and 30psi regulator, Olympic Analog Pyrometer and (2) 40 gr '1 shot' Clay Crucibles. The KK-8 is constructed of a stainless steel tension-adjustable jacket, surrounding alumina silicate refractory insulation that comprises the interior of the kiln. The refractory insulation has an operating temperature rating of 2300° F. We offer the only sectional kiln that allows for easy removal of the crucible before pouring. The liner of the kiln is constructed in a layered and stacked configuration and is less susceptible to cracking from thermal expansion and contraction, as each layer can expand or contract separately. Another feature of the layered and modular design is that individual sections of the kiln liner can be replaced at a fraction of the cost of replacing the whole liner, in the event of a serious spill or boil over of the crucible.
GOLD PROCESSING KILN
Prospectors, are you tired of the tedious process of separating the fine gold from your black sand concentrates? Or, saving it and watching the pile grow, not knowing quite what to do with it? If only there was an easier way to extract it…
Well now there is - burn it! Yes, you read that right. Keep the nuggets and pickers and smelt the rest! This Microwave Gold Processing Kiln is designed and built especially for you. Whether you are a serious prospector, or a weekend enthusiast, this method is sure to grab your interest – and your gold!
The Microwave Kiln is simpler, less expensive and far less tedious - not to mention, more fun – than other processes, such as spiral panners or fine gold tables. All you need is a 1200 watt microwave, a few tools and you are on your way to smelting your own gold at home!
Much research and experimentation has gone into the design of this kiln, to ensure the best results for separating fine gold from black sand and ore concentrates - and for smelting down old jewelry. The stacked or layered design allows for replacement of damaged pieces, in the event of spills, while the kiln can be rearranged and stacked to different heights, according to the size (height) crucible used.

FOR SENSOR OR INVERTER MICROWAVES
Sensor or Inverter microwaves will only operate at high power for approximately 30 minutes. After 30 minutes or so, the microwave will reduce the power output to 80% and begin to cycle the magnetron on for 20 seconds, then, off for 10 seconds. You cannot reach smelting temperatures operating on lowered power output like that in a reasonable time frame. Simply stopping the microwave and resetting the time and power level will not force the microwave to operate at the full power output mode.
1. Program the microwave timer for 30 minutes. Set the power level to High or 100% and start your microwave.
2. Stop the microwave after 29 minutes and UNPLUG the microwave for 5 seconds; this clears the memory on the controller board.
3. Plug the microwave back in and program the timer for an additional 30 minutes and set the power level to High again
4. Start the microwave and listen for the hum of the magnetron for a few minutes. If the magnetron does not cycle on and off, the microwave is operating at the preferred full power level.
5. Additionally: Elevate the microwave a couple of inches off the surface and place a small fan behind it to dissipate the heat coming from the microwave and help keep the magnetron cooler while operating.
This will allow the microwave to operate at full power for the recommended 60 minutes smelting time and reach the temperatures necessary for successful smelts.
