  • Good quality, arrived intact.
Color: 2600f Rated Size: 4 Pack
I ordered the medium weight brick as I thought it would fare better in shipping. The bricks were well packed and only had slight damage to some outside corners. The brick is easy to cut and work with regular woodworking tools.

  • Best firebrick I have ever had
Color: 2600f Rated Size: 4 Pack
These bricks are absolutely perfect for electric furnaces. The inside temperature of my furnace was around 800 degrees Fahrenheit while the outside was around 100 degrees Fahrenheit. When placed right these bricks out perform standard fireplace bricks. From experience with these kind of bricks, they can be glowing orange on one side and be in your hand on the other side. ... show more

  • Gonna be a little beat up. Accept that before you buy
Color: 2600f Rated Size: 4 Pack
Mostly intact with a few busted corners and lots of dust in the bubble wrap. After reading the cancer warning sign about the dust it made me a little worried about getting it all cleaned up safely. Be aware that these bricks are very soft. They are going to crumble and the corners after almost certainly going to break in shipping. While mine were very well wrapped they still lost a few corners. Just accept that before you buy them. ... show more

  • Fire Bricks
Color: 2600f Rated Size: 4 Pack
First off I gave these 1 Star for “Light Weight” because they are Fire Bricks which are heavy & should be heavy! They are nicely marked but they are costly. They arrived quickly & were packed very well!
