The standard one time use is silica and plaster, I've used other silicates like diatomaceous earth with some success.

The best success boost has come from being able to back up a mold with a "container". Either by pouring your mold in a steel box or can, or banding thin sheet around it.

I haven't cast with the bomma yet, but most of the time with cullet you will end up seeing the ghost of every piece. You can sometimes get around it if you do the flower pot method.
