Granite dust source question

Does anyone know if granite dust/decomposed granite is available locally, either for purchase or collecting?

Thanks!

I think most chicken grit at the farm supply store is granite. It comes in different sizes for chicks/adults. Don't know if it would be fine enough for 'dust'.

June,

I get mine from Fox Farm Supply in Burnsville. They have two grits. I just bought two bags so if you want some - come on buy. I certainly don't need this much. I have fine and coarse. Fine for the chicks and coarse for the hens. 828-467-5020.

Thanks John, I'm super busy at the moment, but next time I'm heading in your direction, I'll give you a call. Is the fine,fine enough to use in a glaze.
When I lived in Oregon I used to just collect decomposed granite myself. In some areas, garden centers or places that sell mulch, sand, etc,sell it but I haven't seen it anywhere around here.

June,

No, it is grit. but could be ball milled.

But Vulcan stone (the black rock on all the roads) is granite. You can go to the end or a driveway that is sloped and find a pile of fines and that works. I have used that. I can bring some from home if you want?

I don't have a ball mill, but I'll take you up on the offer of a bit of your granite dust. I only need enough to do a side by side test of a granite/wood ash glaze that I reconstructed without the granite; but I'd like to do a side by side test for comparison.

Thanks!

June,

Will leave it by the studio door. It is a rice clear container with Vulcan Road Grit 80 M on it.

An English potter who used granite 'dust' in several glazes got his supply from gravestone carvers. Never tried it but should prove a supply of fine dust.

What's your ash + granite glaze, if I may be so bold?

Also, my whole-house water filter supplies some granite granules, though not very fine. Haven't tried these granules in a glaze; they just keep accumulating. hp
