    This is awesome. I was visualising something similar but could not quite see the finer details. I thank you for filling in the blanks for me. The square wooden outer is clever. A couple of thoughts. I know carabiners are cheap, although not a buck in my country, but I would probably buy a pack of Hard Facing welding rods, which is a super hard material that you build up on wear parts. Then give it some more weld every so often as required. Then instead of the large metal tube you purchased, I was imagining using an old car brake drum. Or weld up a 10+ sided polygon from smaller bits of flat bar so that the rocks bounce more which should pulverise them even faster. And for sound dampening, I wonder if glueing the large tube in place with silicone instead of epoxy, being somewhat flexible there will be less conduction of vibrations for the neighbours on a quiet tranquil Saturday morning! Maybe a strip of rubber glued to the base and side. To make it much less of a drum.

    Friend! Im not sure to what degree of chemistry you're practicing! But I would really recommend that you line the interior of your fume hood with some sheet metal! This will be a wise investment seeing how at times solutions can burp out their corrosive or flammable components, shielding the interior would save you countless time and perhaps cost from damage and cleanups are so much easier with a metal skin! Plus its way safer then flammable plywood, so you'll have piece of mind. Nitrogen dioxide has such a tendency to make cellulose materials barbecue into carbon, and lets also keep in mind those pesky but beautiful halogens that love to take nibbles out of anything within a foot from them😂 just trying to advise you! My first DIY hood had gotten so contaminated in my Fischer price days, i had to tear it down because the plywood acted as a sponge. And days after an experiment the smells would linger on, i started thinking that this could be counterintuitive and wind up costing much more than I was able to budget! Take care

    • @orophilia

    I worked as an assay chemist in a gold refinery long ago. Your comparing of the color and translucency of the solution after the stannous test was new to me. What we would do instead is cook a tiny crucible on a Bunsen burner. Let it cool and get its weight. Then we would precipitate our AR with Au solution with sodium sulphite. Testing only a drop at time to see that all gold dropped out of solution. Then we would filter the Au precipitate out using ashless filter paper and fold up the paper with Au and put it in the crucible we just found the weight of. Then we should burn the paper in the crucible till only the gold was left. Then let it cool and weigh again. The difference in weight is the amount of gold that was in the solution. If the amount of gold is only a stain then you will need a very sensitive scale. So your visual test may have some benefits in trace amount analysis. But be aware the purple color comes from colloidal gold in suspension. Over time that colloidal gold will sink to the bottom of the test tube changing the translucency of the solution. ❤❤❤❤ Very exciting things you are doing. Thank you for your video.

    As a Geochemist with 33 years of experience in the field, I have to say I like your procedural processes, keeping track of everything. Now I'll give you two bits of advice. The moment you introduce the word "pan" into the concentration process, you are shooting yourself in the foot when it comes to fine gold and second, bismuth requires lower temps in the cupellation oven which creates other issues with the digestion of the various oxides. There is a reason that every ISO qualified assay lab in the world uses lead as a collector metal. Best of luck from a new subscriber! *Edit You have got to get yourself a riffle splitter. All that mixing and dividing with a sheet of brass...Just shovel it in. They are hard to find. Mine are hand made.

      Hi Rockbutcher. Yes, at the moment I've abandoned Bismuth because I can't get it to work reliably at any cupellation temperature. I agree with you about panning; I can't get consistent results to the accuracy that I'm looking for. Thanks for the comments, very useful.

      @@orophilia Thanks. The QA/QC thing is a rabbit hole that will swallow you whole. I've been down it several times and every time the result is, "Trust your lab." LOL That stuff from Jason looks to be mostly fine gold, so a statistical split of say a 1kg sample to a 30 or 50g charge should give you a pretty accurate result. Three runs of the same mass of the same sample will tighten up your result. My problem is that a lot of the lode gold that I'm involved with can be quite coarse, which means that even when split well, the fraction that gets pulverised and fired may not contain the one or two 'nuggets' that are present in the sample. Then we have to re-split the crush and re-pulverise another until we get a result. This is why I have no hair left!🤣

      @@rockbutcher It took me at least a year to really understand the nugget effect. Yes, it will drive you crazy chasing phantoms.

    I have ultra fine gold to sell to you for your bump table testing, or if you have a bump table to trade for some fine gold?

      Thanks, but I now have enough fine gold for testing.
