Seems that a lot of people advocate filling behind the horn with concrete, but does that ever add some weight.

If you want to take the curse off, try 8 parts vermiculite to 1 part portland - ends up about 20 pounds per cubic foot, vs about 150 pounds per cubic foot for conventional mix.

I've been thinking that I might try casting some large horns with it this fall (emphasis on "thinking")
