I'm currently using this as the lining of foundry furnace, within a steel shell. I used a 2" outer layer at full thickness and, by slicing it into 1" swaths (not necessarily recommended), a 1" inner layer which could be easily replaced if damaged. I sealed exposed surfaces and the abutting surfaces between the three tiers of my furnace (specific to my design, ymmv) with sodium silicate to keep it from shedding, but have chosen not to bother sealing the inner faces until and if it becomes necessary. A utility knife cuts fiber blanket fairly well, but blades dull quickly. Use a well-fitting face mask when working with this material as its microscopic airborne fibers can cause lung damage. Mine is a 3M full face mask, but that might be overkill. I also wore coveralls which I washed after each session, and kept hazardous material outdoors as much as possible.
I recommend using pre-made 1" blanket if you need this thickness. Slicing it the long way produced way more airborne fiber than I would've liked, and I wasn't able to get truly clean cuts (lots of pretty thick, flappy pieces left hanging on the sides, leaving me to wonder whether I should peel them off or leave them attached.
In my limited testing so far, my furnace appears to be extremely efficient at melting aluminum in a steel crucible with my 3/4" propane burner. I may use my remaining fiber blanket to replace the solid refractory in my forge next spring.
The box shipped reasonably quickly, and weighs around 33 pounds. I saw some cheaper versions out there, but I was more comfortable with this product and seller after considerable research.
Bought to line my forge. After a lot of searching trying to find a good deal with the amount I needed I found this. Amazing price fast shipping plenty left over for relining the large 3 burner forge I built. Combined with some kaowool ridgidizer, and a good refractory, which is 100% essential, I would definitely buy again.
does what i want
A+
This insulation is very good is everything I wanted it to be for forging

Description
Ceramic Fiber Blankets are manufactured from spun ceramic fiber and is needled to provide exceptional handling strength for high temperature insulation applications. Blanket is typically offered in three standard grades referred to as commercial, High-Purity, and Zirconia grade. All grades are lightweight and thermally efficient resulting in a material that has the advantage of low heat storage and complete resistance to thermal shock. Blanket is produced in varying dimensions, temperature ratings, and for different applications. Our office also supplies Bio-Soluble blanket which is environmentally friendly. If you don't see a specific blanket listed, please contact us directly and we will be happy to provide a custom quote.
Worked great! I have extra now for future projects! fast delivery!!
Awesome product!!
We got our shipment on time and the product was exactly as it was shown. Perfect!
For any heat application. You can lay this on a pot of molten metal and it wont burn. Excellent insulation for added protection on wood stove or pellet stove installations,
