Gah! You beat me to it! I was planning on visiting him tomorrow. Good for you!

Where exactly in WA? Goldendale?

I let the forge come up to temperature last night and heated a RR spike in it. Got up to a low yellow heat! Probably could have gotten it hotter still. Superwool is holding up so far. Meeco's cement works, but isn't the best. Will probably have to scrape it out and apply something else sooner than later. I came up with a solution for tuning the Frosty T-burner I built, that kind of came about by accident. I purchased the wrong brass fitting to hold the MIG tip, and the opening was too large for the 1/4-28 thread on the top. So I came up with the idea of threading the length of the tip and the inside of the fitting, allowing me to thread it in/out. (Threading a copper MIG tip with a die is a PITA, but can be done!) Little bit of TEF paste to hold and seal it. Worked great!

So, I've got my forge together and given it a couple of quick firings to check it out. I haven't let it come up to full temperature yet, and haven't tried to heat any steel. Here's a short video clip. 20170416_215855.mp4

Thanks Frosty! ITC must have changed the MSDS. Under the Composition heading it now reads "Non-toxic ceramic components; Proprietary formulation". I haven't committed to a refractory for the flame face yet. There's so many choices. I have been considering Meeco's Red Devil furnace cement, as it's rated to 3000°F, as it's cheap, readily available and it some folks have reported that it works. Here's a picture of what I've got going so far. I left part of the handle flange attached to the tank. I figured I could place half a fire brick there as a porch.

First time post. I've been poking through the forum, and I've seen differing information and opinions regarding Superwool. I know Wayne Coe on his website says he's had low demand for it, and that it has a lower constant operating temperature than kaowool. But I've also seen others that love it and say it has a higher temp rating than kaowool. I thought I'd start a thread dedicated to it to collate all the opinions and information. I'm slowly aquiring materials and components to build my first forge from a 20lb propane tank with Frosty's T-burner. The reason I'm asking specifically about the Superwool is I found a potter's supply store in Portland, OR that sells 8# Superwool at about $10 a YARD (by 24" wide)! This is WAY more affordable than any source of kaowool that I've found (besides getting it for free, but I've been having trouble finding a source here.) I picked up 2 yards of it today, because I figured "Hey, $20?!? Why not? If it burns up, I'm not out too much." Also got 2 lbs of zircopax and a pound of kaolin EPK to try out Frosty's ITC-alike. Once I get my forge up and running, I'll post my opinion of the Superwool, but I'm interested to hear everyone else's experiences with and opinions on it.
