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.
Agrilectric is burning rice hulls and they say they're selling the ash. I didn't find any cost info.
Here's their web page.

I found at formula for rice husk ash in my notes, if anyone wants it.
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.

Let me know.

Thanks for the reply.
It is very nice of you to take the time to write.
I got some of the stuff from McKenzie but Joe Brecha was wondering about a bulk source for his supply business in Tacoma Washington.
I will pass it on.

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
