Anyone know where I could find rock wool, or iso wool or anything like that? I'm thinking about building a small propane or MAPP forge and I want to see how much I'm going to need to build it.

 

I found some rock wool insulation on home depot's website, but I'm not sure if its the right stuff.

Lumber yards sell it.

McMaster-Carr has it. Search their site for "refractory insulation". They have everything you will ever need...ever. No need to ever leave the house again.

Home Depot. ROXUL is the name. I bought it there a couple years ago when installing a wood stove. I think I have a a small section leftover if you want just a piece and don't need to buy a whole bundle.

found it if you want it. It's 3' long.

I built a ceramic coat and powder coating oven a few years ago. I used rock wool insulation to make the panels. I bought 11lb 3 in thick panels from McNeil in Robbinsville NJ. I was easy to work with and comes in different weights, and thicknesses. McNeil was easy to deal with.

N2BRK: I'll let you know. I shouldn't need anything to large, just enough to insulate like a paint can. All I really need it for is heat treating small pieces of steel.

 

I totally forgot about Mcmaster-Carr. I'll check them out, hopefully I can get everything from there in one shot for cheap.

You can absolutely get everything in one spot. Cheap on the other hand should not be used in the same sentence as McMaster.

McMaster-Carr is the shit. Don't expect discounts or coupons. But expect every small piece of industrial equipment delivered to you the next day if that's what you want. Including smaller-sized Unit Operations (oil/water separators, tanks, mixers, common membranes, etc.) And every standardized mechanical part on the planet.

The one thing they didn't seem to have (I probably didn't look hard enough) was satanite. Its a ceramic super-high temp paint that can operate from -5 to 2400 F. They had similar refractory coatings, but they were realllllllly expensive for my application.

what about header paint from an auto store? VHT Flameproof is good to 2000*F. I'm sure there's better.

Any plumbing supply will have refractory blanket that you can mold to shape and refractory sheets you can cut to size. These are used for the combustion chamber walls of oil fired heaters.

I can look into header paint. The forge shouldn't get any hotter than 2000 any way. Hopefully Advance has it and I won't have to go traipsing all over to find it. I'll hit the local hardware store tomorrow if it isn't a shitty day out. Worst case is I order some Mcmaster, and get a fire brick with it too.

fire brick should be easy to find at hardware stores or definitely at Tractor Supply; look in the fireplace/woodstove section.
