Gold prospecting has the advantage of today's use of ancient gold prospecting tools with the modern day machined tooling dowsing rod aiding in dowsing for gold. In the 1970"s my father and I reverse engineered the physics involved in dowsing and invented the modern light weight ball bearing dowsing rod for applying dowsing physics in locating our old core-drill on the exact center of gold and silver veins that are buried under 200 feet of glacier rock and till, which worked out perfectly for us. These dowsing physics and dowsing techniques are too important to the world for myself to selfishly take to the grave. So I wrote the book to teach the world how to apply physics in dowsing for any sought element, with marketing my book at the lowest price possible so that more people will be able to buy my book and learn how to dowse. My book's name is: The Art of Dowsing - Separating Science from Superstition ($14.95), by Michael Fercik. My book explains all the physics involved in dowsing (the same physics that energizes the alarm on electronic metal detectors), and explains how to build the modern light weight ball bearing dowsing rod, which is the only dowsing rod that accurately gauges what is being dowsed by pitting the energy of gravity against the energizing of the pure one-tenth ounce dowsing rod load that is tapped onto the ELEVATED acetylene welding rod, which free spins on ball bearings. This precisely gauges the dowsing of all edges, exact center, depth buried with angle of deposition, and most important is grading or deciphering the amount of the dowsed element that is contained in the elemental mass being dowsed. Everyone can become a professional dowser by practicing my book's dowsing lessons of buried pipelines and electrical cables, tunnels and voids, precious and base metal placer and load deposits, dowsing for treasure, dowsing for any element, amplified long distance dowsing from a moving vehicle, and dowsing on water from a boat. I hope dowsing enriches your life intellectually and financially.

I think you can cook the borax to dry it out. I have done that with copper sulphate that was in a hydrated state.
@LetsCrushRocksКүн бұрын
That's actually how I make soda ash (sodium carbonate). Just take baking soda (sodium Bi-carbonate) and still it in the oven at 200F for about an hour. I'll look into that for borax, though I seem to recall seeing a video where they said you had to actually get it to melting temperature to reduce it, then pour it out, let it solidify and break it up again. Quite a bit of work!

@8thsinner2 ай бұрын
What you really need is a vacuum set up somehow and one way valve to drop rocks through so the dust flying up gets collected but rocks don't escape either. If you shortened the exposed bolt you would be removing the mass there which is adding to the wobble in the unit, looks good and solid though.
@LetsCrushRocks2 ай бұрын
I've seen others where they have an outlet port that drops into a bucket with a sealed lid. The lid then has another outlet tube leading to a vacuum so the material drops in the bucket but the dust is drawn out of the top. I think I might give something like that a try! Thanks for you thoughts on the wobble. I might look at chopping some of that extra bolt off! Cheers.

You could get the temp that high, but I dont know how even the heat would be. I haven't done anything with pottery before but I would guess it needs to be an even heat. You'd want to elevate the clay in the furnace to make sure the flame isn't hitting it directly at the very least. (I had to Google what "raku" was by the way).

You could adjust the gas flow with the valve and the pressure regulator to help with some temp control. You can also leave the lid off to start with as things are heating up and then put it on later, I do that when I first start up the kiln to drive out any moisture since it since sits in my shed often for months without use.

I don't think I would bother with the outlet port and just load from the top, crush, and then turn it upside down to dump out. The large washer in the middle used to hook on the chains is weak and bends after a while, eventually breaking. I have doubled it up but it still bends. Would recommend replacing it with something thicker. I don't have a drill press so its hard for me to drill large holes through thicker steel. I saw a recent build video by Orophilia that was really good, he makes a nice crusher.

Years ago, someone gave me a small commercial smelter - Foundryette - is the name on it, I cant find very much about it on the internet. It came with a squirrel cage type blower that the propane is plumbed into. They have me a 5 gal bucket full of crucibles as well. Ultimately it is alot like the one you created, except the air induction. I only had to buy a regulator and it works well. If you would like, I can take a pic of the label on it, like I said, it was a commercial made for sale type item. I smelted 8 grams of placer gold into a fair sized button, and due to the borax managed to get rid of any small impurities that might have been mingling with the flakes.
@LetsCrushRocks Жыл бұрын
Very cool! I melted a few grams of placer gold into a small button last year as well. Though I found if it is very clean placer gold, putting some borax in it, sitting it in a cupel and hitting it with a blow torch was much faster at melting it into a bead than in the kiln.

Good point! I will see if I have time in the next few weeks to post an update video with some more shots of it in use and lessons learned. In a nutshell: The burner works excellent and I have had no problems with it. I used the furnace perhaps a half dozen times and it worked well each time, getting to >1100C without turning the burner all the way up. However some of the plaster, particularly where the lid and bottom portion meet, did crumble a bit. I think it may be because I did a poor job mixing the material in small batches instead of one big consistent pour. Because the lid and bottom section did not match up smoothly, some heat and gas were escaping out the sides, which I believe also contributed to it wearing down at that spot. Unfortunately, it sat in my shed for about 8 months unused, including over winter, and seems to have absorbed some moisture. I am in the process of repairing it and will try to include that in an update video.
