    The other item I am attempting to locate is an atomizer. I will make one if I must, but I would prefer to find one instead, if possible.

    Any help would be greatly appreciated.

    Thank you

    Scott you can purchase cast-able refractory from any pottery and ceramic supplier it comes in bags like cement, get the highest temperature refractory used for making kilns.


    Hers how I made my furnace, used an old bladder water tank, cut the top off then a hole near the bottom for the torch entry, mixed up a small batch of refractory then poured the floor first let this cure overnight. Next day inserted a plastic garbage can centred then filled it with sand before filling the outside perimeter of the garbage pail inserted a piece of 4 inch plastic into the torch hole.

    Then poured in more refractory to fill the gap around the garbage pail, once the refractory had cured removed the sand, now the plastic pail was easily removed, to make the lid i cut a hole centre, then coming in from the sides a few more holes large enough to insert spikes. What i now had looked like an inverted ships wheel, anyhow the idea behind the spikes was to hold the refractory firmly in place inside the metal shell.

    You may want to line the furnace with cerwool also known as kaowool before filling it with refractory, its amazing stuff. i can run my furnace for hours and still put a bare hand on the outer shell the cerwool does a good job of keeping the heat inside where it belongs.

    Atomizer, not really sure what your looking for are you trying to make cornflakes or shot from your melt, there is already a good write up on this at the gold forum. You can find the article by searching these posts. Gold Refining Forum.com • Information
