Everything Mac Posted January 26, 2016 Share Posted January 26, 2016 Hi all, I'm about to pull the trigger on buying some ceramic blanket to line my forge. However it seems there are two densities available? 96 and 128kg/m3 Which one should I go for? I'd have though the heavier blanket would be better?

Frozenforge Posted January 26, 2016 Share Posted January 26, 2016 The 96kg would have better insulating properties but would be more fragile. I dont think it would make much difference on an average size forge. Quote Link to comment Share on other sites More sharing options...
timgunn1962 Posted January 26, 2016 Share Posted January 26, 2016 The 128 kg/m3 is the better choice. It's 8 lb/cu ft in old money. The 96 kg/m3 is 6 lb/cu ft. There is also a 160 kg/m3 (10 lb/cu ft) blanket available in the 1425 degC / 2600 degF grade, which might be worth paying a bit extra for if you can find it. The higher density stuff is actually the better insulator, according to the spec sheets. http://www.morganthermalceramics.com/sites/default/files/datasheets/cerablanket_cerachem_cerachrome_blanket_english.pdf Quote Link to comment Share on other sites More sharing options...
Everything Mac Posted January 27, 2016 Author Share Posted January 27, 2016 Hi Tim, Fancy seeing you here. I was just looking at your amal burner threads over on BB. I had been building a DIY burner but I think I'll just bite the bullet and get an amal injector bought. I only found one place that sells the 160kg/m3 and that was out of stock. I'll get some 128kg/m3 blanket for now. I don't plan on welding in it for the time being so that should be ok I'd have thought. Cheers All the best Andy Quote Link to comment Share on other sites More sharing options...
