ede Posted October 30, 2016 Share Posted October 30, 2016 I was given a large trash bag full of unused fire blanket by another blacksmith. He got it from a guy who was doing a pizza oven install awhile back and doesn't have any specs on it. While I have some 8# 1" 2600 degree rated fire blanket, I was wondering if it's worthwhile using this oven blanket as an outer layer in my forges and the 2600 on the interior? A quick google search for pizza oven blanket turned up this product which is rated to 2300 degrees: Forno Bravo refractory ceramic fiber insulation blanket is used in all our pizza oven kits and fully assembled home / commercial pizza ovens. Also suitable for furnaces and stoves. Woven ceramic insulating blanket comes in 50 sq. ft. roll, 2’W x 25’L x 1″ thick. Easily cut and shaped for creative pizza oven designs. High efficiency insulating blanket for installation under any refractory or brick oven. Heat resistant to 2300ºF (1280ºC), easy to use, and more efficient than vermiculite by a factor of 2 to 1. Fast and simple installation saves time, space and money. Thanks! Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted October 30, 2016 Share Posted October 30, 2016 I would imagine so, as my forge with 1" is touchable on the outside. I didn't say you wanted to hold your hand on it tho, it dose a good job of heating lunch... Quote Link to comment Share on other sites More sharing options...
Frosty Posted October 31, 2016 Share Posted October 31, 2016 That'll work fine. What do you have for a hard inner liner? Even rigidized and with a good kiln wash ceramic blanket will suffer mechanical damage so having something hard for the inner liner is a good idea. Frosty The Lucky.

Did that match the label on YOUR blanket or was it just a guess as to what you have? Quote Link to comment Share on other sites More sharing options...

Frosty, After lining with the non-pizza oven blanket, I used rigidizer mixed with some food dye and a drop of dish soap to break the surface tension in a spray bottle. Then, I used 30% kaolin and 70% zircopax per what I read here on the forums from several members into a latex paint type consistency. I've noticed that there is some cracking after the coating has been applied, dried and fired. Another member pkrankow recommended a grog that might help with this. One of the guys at the supply house I spoke with suggested aluminum hydrate as a common ingredient as a kiln wash. Has anyone else tried Al(OH)3 in a blacksmithing forge application? Since this is a new forge, I am going to pick up some kiln shelf. I have some Mizzou as well, and would like to try it again some time but next time just for the floor instead of the entire inner circumference. 1 hour ago, Glenn said: You did read the part about for installation under any refractory or brick oven.

Hi Glen, It's just a guess that this is a similar spec'd material as the blanket I received came in a trash bag with no info. The rest is hearsay.
