Color: 2300f Rated


Size: 1 Single


Features

  • Great insulator with low thermal conductivity and very low weight
  • Easy to shape, cut, and carve with wood working tools
  • Used for kilns, forges, furnaces, knife making, PMC metal clay firing, jewelry casting, or jewelry soldering block
  • Specifications: 2300F rated, weight 2.1lbs., 9" x 4.5" x 2.5, alumina silica refractory ceramic clay brick
  • See Important Safety Information below

Description

The Insulating Fire Brick (IFB) is a type of soft brick made of refractory ceramic material, a blend of alumina and silica, that can withstand extremely high temperature applications and has a low thermal conductivity. This IFB is an excellent insulator and reflects heat well. Insulating Refractory Fire Bricks are light in weight and can be easily cut by handheld hack saw or any other hand tool like chisel or drill. They are ideal for creating custom shapes and cavities. IMPORTANT: Do not confuse this lightweight Insulating Fire Brick (IFB) with the dense Firebrick. Hard Firebricks are much heavier, harder and difficult to shape. Insulating Fire Bricks are softer, much better insulators, and easier to shape. For example a 2300F rated IFB weights only 2 lbs. The same size hard firebrick weights more than 7 lbs. Important Safety Information DANGER All Insulating Fire Bricks have a hazard communication warning label and prop 65 warning for airborne fiber inhalation. Please consult the Safety Data Sheet for more information. HAZARD STATEMENT This product contains crystalline silica, which if inhaled in the form of quartz or cristobalite over a prolonged and repeated period is known to cause cancer. This product does not present a hazard if dust is not created during handling. PRECAUTIONARY STATEMENT Avoid creating airborne dust. Avoid creating airborne dust, by only using hand tools. Frequently clean the work area with HEPA filtered vacuum or wet sweeping to minimize the accumulation of dust. Do not use compressed air for clean-up. Individuals should wear gloves, goggles and an approved respirator if dust is present. SAFETY DATA SHEET Upon request we can provide the full SDS sheet for these products.

You may drill little holes in the brick to keep your jewelry in place while soldering. The fire brick allows you to solder more quickly and efficiently because you can concentrate the heat where you want it. PMC+ and PMC3 Metal Clay Firing: Jewelry makers can use this fire brick as a safe surface for firing metal clay with a butane torch. Kiln for Pottery Making: This insulating firebrick is also great to build larger kilns for pottery makers. If you have a missing or defective kiln brick, you found the perfect replacement brick to fix your oven. Build a Mini Forge: The Lynn Manufacturing Insulating Firebrick is perfect to build a mini forge for knife making. There are many tutorials online on how to use fire bricks to build a mini forge. Read more Structural density is in direct correlation with how brittle or soft the brick is. A 2300 F rated IFB is much softer and brittle than a 3000 F IFB, but the insulation is much better on the 2300 F rated brick. The insulation value after all comes from the porosity in the material. You can see the small voids in the detail pictures. Please choose your brick according to the properties for your desired application.

This product causes CANCER!!

I received these bricks with a strong warning label attached: CAUSES CANCER WHEN INHALING DUST! Nowhere on the order site was there any mention of carcinogenic effects caused by handling these bricks!! I immediately threw them away. I have cancer and I don't need additional exposure to carcinogens!! BEWARE WHEN ORDERING PRODUCTS ON AMAZON!!!

Low quality

I was expecting much better quality for the price. The product arrived in perfect condition. I bought 2 bricks 2600F. Both of them seem of different quality (although they were both market "26"). In one of the bricks, one of the corners pulverized. They are going back. I would not recommend this product.

Very effective!

Holds enough heat for a nice bright yellow on 1095, W2, and some rebar in my little baby home made no weld forge heated by a propane torch. Bottom is the hard fire bricks, sides and top, and the "doors" are this type. Cut some slots into a scrap piece to hold knives upright - that's what's in the middle.

Gonna be a little beat up. Accept that before you buy

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.

Excellent product.

Used this as the floor and door of my mini foundry. Works extremely well. Very easy to cut with a wood hand saw. Follow precautions.. wear a mask.

Excellent product

After all the reviews complaining about the bricks arriving broken or chipped, I didn’t expect much. My package of four 2300° bricks arrived beautifully packaged and in perfect condition. I’m using them along with nycad wire to make hangers for pottery test tiles.

Very poor packaging...

These fire bricks are great for insulating my forge. They do a great job insulating and dispersing heat. The only problem is that they were packaged so poorly, without any protective cushioning, that there were chunks broken off the corners when I opened it up. I can’t even blame the delivery driver, because these bricks are very delicate and the fact they survived at all was kind of amazing considering how they were packed. Be advised that you may need to order 1 or 2 extra so you are not short due to damage done in transport.
