Got someone interested and is having trouble.

    It used to be sold for only around $2 a bag, as Kleen Sweep; but I think they've now added oil to it and are selling it for a great deal more.
    Rice hull ash is around 94% or so of pure, fine silica, so you could use something like amorphous silica as a replacement for most of it and fill it in with the other oxides in small amounts. A glaze chemistry program should be able to get you close enough to the formula.
    I think one possible test is to replace 94-95% of it with the amorphous silica and the rest with wood ash. That would give some of the trace minerals and some carbon, which the rice hull ash has.

    Mackenzie Smith bought a bunch for the spring concentration. Susan Feagin might have his source.

    Hey John,

    I purchased a 50 pound bag from Industrial Minerals in Sacramento a few years ago. I would be willing to ship 10 pounds or so if that would help. I have more than I will need.

    Best,

    Craig

    Craig,

    That is nice of you, but I have enough for myself, I was trying to find a reliable source for Joe at The Clay Art Center in Tacoma.

    I will have him look a the posts and hopefully he will get back to you.

    Thanks,

    John
