If I was just starting out and didn't have any other torch AND I had the other stuff on hand, maybe. If I had to go out and buy everything, I would still go for the oxy/gas setup, and probably use propane. When I bought mine, the kit, with hoses and tips was $98 on sale. It was a light to medium duty kit. I added better back flow preventers that cost about $35 at the time. I also bought a propane tip for it that was $29. I bought a 5 foot tall bottle of oxygen that was about to run out on the inspection date for $40. I only use it for gold, so it is still roughly half full. All of this was around 10 years ago. Roughly $200 in total. I was gifted a $2 clay melting dish that I very carefully heated and glazed. I melted gold in that dish, or parts of it, for two years. That torch can still be used for cutting steel or scrapping metals. I can weld better than fair with it as well.
It has sat out in the weather this entire time, and still does till this day, (I do keep the torch head in the dry)? Try that with a microwave 😁.
My point is when looking for tools to use in refining, look for those that will take a beating, has multiple uses, and is cheap and accessible.
One can always replace them with better tomorrow without breaking today's bank account.
From day one, refining for me had to be able to show me that there was a possible profit in it, even as a hobby, (like I needed another hobby).
I still run on the basic tools and methods and have had a lot of fun at it. I have experimented with many of the "make do" methods and a few were successful, many weren't. I don't doubt that a microwave could work, I just can't justify setting it up if there are any other options.
 
Believe what you may but I used a Potatoe to prosses some amalgam 40 years ago that gold is still scattered in the yard. A proper retort is the way to go with amalgam. And a microwave oven I'm still reading.

I do not think there was a microwave oven included in the Amalgam process.
If you search 4Metals posts he has described it before.
And I concur, retort is the way to go when Mercury is involved.

Correct but I think @Southfork realizes that. How the lowly potato was introduced into a thread about melting gold in a microwave I do not know. Melting gold in a potato is via torch in a hollowed out spud. This is done using the potato as a crucible. Using the potato to absorb the mercury from amalgam is a different process, one which Southfork realized long ago has some shortcomings. I have witnessed it being effective, but I hold out for more modern technology. Plus it leaves the potatoes available for dinner. A retort is the only way I would approach mercury in scrap be it dental amalgam fillings or amalgamated black sands.

And the microwave....... I've decided, but the jury is still out for others.

The potato idea was mentioned by SGBog here: https://goldrefiningforum.com/threads/microwave-gold-smelter.8483/post-298905
I asked if anyone else had tried it since SGBog is no longer active. I referred to potatoes being used as crucibles to demonstrate their insulative properties, indicating that their use as a crucible in a microwave may have some merit. Of course it's not going to be the best way to melt gold, or the best thing to do with a potato. I was just intrigued to find out if it were possible. It seems I will have to find out for myself :LOL:

By the way, the other videos by My Adventure are worth checking out, he has a very interesting panning technique for microscopic gold.
 
Microwaved smelting in potato for 10min no sparks because I put the top back on the potato. No metal exposed no sparks. this was part of the discussion I read and was just thinking about what happened when heating a sealed Potatoe regardless of its use. My Potatoe exploded on coals in a campfire. Good luck I'm waiting on ore samples cooling in the gas furnace contained in a crucible no potatoes.

The key is having a working microwave that you are getting rid of so no cash outlay. The concept is good for assay size fusions and small melts as demonstrated in many Youtube video's in this thread, all you need is the firebrick inserts. The down side is one assay fusion at a time. I am spoiled as I always used kilns like these where the smallest one can handle 4, 30 gram crucibles.

I have a large 220-volt kiln that was given to me have never tested it's super heavy lined with fire brick. I was thinking about heating it with propane if we ever hit the motherload.
