what type of clay to use for a BBQ grill? where to find it?

[Guiltyspark]

I have an old BBQ laying around and was wondering what type of clay i can use to protect it and where to get it?

<sup>Old-N-Rusty suggested a sand and cement mixture that has worked great for me on my rivet forge-
3 parts sand and one part cement (portland cement not concrete) mixed moist and molded to shape.

Hope this helps.</sup>

I did a lot of searching for this too, the stuff I came up with is more like refractory cement, but is supposed to work well (mine's still setting, no cracks or anything!) About 2 parts portland, 2 parts sand, 0.5-1 part dry lime, 1 part clay and 1 part perlite. The clay can be found by getting 100% clay kitty litter or at a masonry supplier if you're lucky. The perlite is almost identical to the stuff that they make firebricks from, but holds less moisture so is better for cementing- this gives it it's insulating qualities. You can get it at garden centres.

First mix everything but the clay thoroughly, moisten, then mix in the clay. Get it just wet enough so it all sticks together and spread away! This stuff is a bit OTT, but you're forge will be both bullet and idiot proof. Something which apparently I require!

look into woodfire clay bodies from a pottery supply house. I have seen them rated at cone 14+
