Heavy Duty Refractory Fire Bricks for Forge 3200F - Pack of 2 Extra High Temperature Insulated | Fire Brick for Masonry, Insulating Kiln, Fire Pit, Wood Stove, Oven, Grill, Melting Metals

I actually won't be using these fire bricks until the Fall. But, based on thier weight and solid construction I'll assume I will not have any complaints.

Update: Contacted seller and they are sending me a replacement brick, wonderful service!Bricks fit description perfects, good for the mini forge I built. Corners chipped off during shipping I assume, overall still usable.

I purchased this bricks for a forge floor, and I've actually never purchased firebricks of such good quality.You'd think that firebricks are all the same, but I'm here to tell you that isn't all true. Most bricks I've purchased have chipped and crumbled as I was working with them, but these big fellas were installed without a scratch on them. Even now that I've been using my forge, they're still perfectly intact.They arrived very well packaged and secure. I will be purchasing more, when I need them.

I'm using these for the floor of my propane forge. They are heavy and holding up well.

After using our new fire pit for almost two months, I can attest for the great quality of the GIRtech Forge High Density Heavy Duty FireBrick 3180 F. Everything is right to the expectations or even better. I would highly recommend this product to anyone!

These bricks have held up very well so far. Have a double burner forge and I’ve seen these bricks glow with a bright yellow glow and still no signs of cracking or breakage.

🔥 Jade Ann Byrne Amazon Review — Beauty Forge EditionProduct: GIRtech Forge Heavy Duty Fire Brick 3200°F (9” x 4.5” x 2.5”)Purchased: October 14, 2023Reviewed: June 22, 2025Used As: Structural support for a marble vanity shelf in a Southern California tract house bathroomHeat Tested? Not in a kiln. In real life.I didn’t buy this brick for a forge. I bought it to hold up a slab of marble in a tiny SoCal tract home vanity, and let me tell you — it’s doing more heavy lifting than half the men I’ve dated.This isn’t just a fireproof, industrial-grade insulation brick — it’s now part of my glam infrastructure. It literally holds the weight of:• A hula girl figurine for emotional stability• Six open serums and a suspiciously sticky retinol vial• An army of acrylic perfume decanters• Glitter, lip plumpers, and at least one uncapped dry-ice-infused tinctureAnd it doesn’t flinch. Doesn’t wobble. Doesn’t chip even when I drop my eyelash curler for the third time that day. It’s been splashed, scrubbed, steamed, cursed at, and serenaded by late-night Taylor Swift karaoke sessions in a fogged-up mirror.Bonus: You know how most fire bricks are dusty and flake? These? Smooth. Dense. Flat enough to support a marble slab without shifting. Basically… minimalist throne material.Final Word:If you need a vanity base that can survive the fires of your transformation, this brick is it.It’s a forge brick, yes — but it’s also the foundation of my femme architecture.

Hard. This brick cannot be broken without intent. Also the fact that fire cannot destroy it makes this a plus.
