Im not sure whether to post this here or in UDS builds but since its about bricks i thought about posting here... anyways ive built a UDS but want to use fire bricks to insulate the bottom. I have access to used free chimney bricks that i was thinking i could use instead. Im just wondering if chimney bricks are the same as fire bricks. or if they are different can i still use them safely. i dont want chemicals from the bricks going into my food.
can anyone help me out?
