USM-4 Heavy Duty Firebricks 4-Pack Fireclay, Chamotte 3000F US Stove 9" x 4-1/2" x 1-1/4" Insulating, Replacement Fire Bricks for Fireplaces, Wood Stoves, Pizza Ovens, Steel Furnaces, Forge

First firebrick to hold up all winter long.

I am starting my first smith shop and these were amazing for the price, with high quality, and perfect size. They take the heat and worked great. I dropped one and it did hardly any damage and looked the same as if I had not dropped it mostly.

Good quality fire brick; I cent the down with a wet saw so they would fit in my furnace. They are holding up to the heat and give my crucible a good solid spot to sit. Unfortunately I found a box of 6 at Menards for like $18; I guess I should have looked around locally a little more.

Just like what I expected.

Very happy with these bricks-

So very pleased with the quality of these bricks. They are what was needed for our stove! We will buy them again!

Does the job!

Nice heavy brick to retain heat. I replaced all the bricks in my blazeking woodstove and these are about twice as heavy as the original ones. The bricks arrived on time and were packaged good enough that none of them were broken, kinda surprised as I live in interior alaska and you never know how it's going to with shipping up here.
