Review on 🧱 AMACO Insulating FireBrick, 9x4.5x2.5 inches by Tara Ford

They insulate well and are easy to cut with an old carpenter's saw. They're pretty soft, softer than some of the other insulating refractory bricks I got a few years ago. This is not a criticism, just a comment. The bad rating is not due to the product, he would have given it a 5. I downgraded it due to the Revain packaging. The stones were packed in a box with other items and air-filled bags, but there was enough free space for the stones to move and bump into each other in the box, and the edges of all six stones were knocked out. It doesn't look like the shipper was overly rough on the box,
