I'm wanting to build an outdoor fire pit, and I've seen online that regular bricks are not recommended, though I'm having trouble finding fire bricks and/or fire inserts at a reasonable price..
If I create an inner lining (approx. 1inch thick) inside the fire pit with a heat resistant mortar/cement (e.g. Scandia 1kg Air Set Mortar), and be sure to leave air holes around the pit.
Would this allow me to use regular bricks only without needing a fire insert or fire bricks ?
Thank you.
