Product Overview
A seventy-five pound bag of conductive refractory. It has similar characteristics to dense fireclay bricks.
This item would normally be used for caps or other items which are supposed to store and slowly radiate heat. We use it to cast our Barrel caps and barrel supports (4" and 6").
From a shipping cost standpoint, it only makes sense to order this from us if you are ordering something else which comes on a pallet.
