300 used hard fire brick, 600 used IFB K23, 48 skew bricks
Recovered from a soda kiln, one face has soda glaze build up, but others sides are fine. IFB were an insulating layer on the outside so are not affected. Skew bricks also were not exposed so are clean. Plenty of life left in all.
hard brick $1/each
Skew brick $3/each
