    I believe a good type of Miller Table will work well to catch a lot of flour gold but I don't have one at this time. As soon as I receive my Blue Bowl I'll see how that works.
    I was thinking about using electricity to help get the gold. But I don't know if that will work.
    I also thought about heating the gold and sand in a small cast iron pot, but I'm afraid the gold will melt and engulf the sand.
    At the present time, I took some flour gold that is mixed with sand and I dried it out. I poured the mixture on a piece of blue paper and now I will pick the gold out as time permits.

    I have an article somewhere from the 60ies that describes making a "long-board" basically a massive miller table that sits at the end of a dredge sluice for cleaning concentrates, an old timer from Trinity County told me about how he cleans his cons right in his dredge sluice by similar action, getting it to sit almost flat with the aid of a two by four, he recommended roughing up the sluice bottom with various grits of sand paper and using a squeegee to work the material around.

    When you get your blue bowl it would be a good idea to wash off any mold release from the plastic but be real careful not to scratch the inside surfaces of the bowl, it needs to be nice and smooth. I like my blue bowl, it does its job though I rarely use it, maybe once every couple years when I have enough sand to bother concentrating, I mostly use a clean up sluice followed by a spiral wheel and delicate finish panning, everything super fine is stockpiled for a winter day. I dry it, screen it all out, remove the magnetic sand with a spin it off magnet then I roast and crush the non magnetics and send it through the blue bowl, works great.

    I am a glassblower and use gold to color my work, different gold bearing regions give different colors due to varying impurities. Fines are difficult to use as it just burns up before it can adhere so I will make a bead out of my fines, to do so I utilize a marble mold made of graphite, you could also use cast iron or better yet a piece of unglazed pottery such as a piece of flower pot. I then mix in with my fine sand and gold some borax with a little water to make a paste, 20 mule team laundry borax is just fine it can be found in the cleaning isle of a grocery store. The borax acts a flux, the stuff can be used in a pinch as a soldering flux and is used by blacksmiths to aid in forge welding. You hit this mix with a mapp gas torch, if you have oxy acetylene it goes a lot faster be careful. The gold all fluxed up with gather together into a bead contained in the glassy remains of the sand and flux, which is crushed up and panned to get the bead. Another great use for borax is for treating athletes foot.

    The carpet I think is a good idea, you can clear a spot and place it right on the bottom, if you want to get real jazzy, use rocks across the carpet to make riffles. Keep in mind with a sluice box you need gradient and stream pressure with the carpet the fines will be constantly moving across the bottom. Think about this a little it's a common sense deal...

    If you decide to use the carpet probably would be a good idea to get some 1/8 X 1/2 flat bar and pop rivet it to the bottom of the carpet with wide head rivets, was thinking a little about this, would stay in place better but you decide, think this setup will catch some fines

    Hello All, I am back.
    Thanks for the email 3cylbill.
    I'm still alive and kicking. I did find a small pc of gold and a bunch of sand full of flour gold. I bought 2 blue bowl separators, first one was new from the USA but the seller shipped it from China. When it was supposed to come from the USA. EBay returned my money and kicked him off of EBay. The second one was a used unit and looks good, but I did not even get a chance to use it yet.
    The wife's car died so we had to buy a new one, ouch! The house needs paint and I am painting it now, just think a 70 year old man on a 24 foot ladder. I hold on with one hand, two feet and my teeth, and their false. So it is taking awhile. Deer season is fast approaching I need to do some scouting.
    So back to gold, I figured out that when my stream is real low and almost dried up I can dig sand and stones with a shovel and put it in a bucket for later.
    What I need now is an honest friend that would look at my tiny pc of gold and some flour gold and make sure I have real gold. I can send it to someone if I knew who.
    Well it is suppose to rain today but the sun is out with no sign of rain, darn, now I guess I gotta start painting again.

    Don't strain your eyes. I tried to crush it but it just flatten out.

    If it doesn't pulverize when you hit it with a hammer, but just gets smooth and flatter, it just might be gold, as long as it has a yellow tint and not grey.
