Hi all, Moose here, Im new to bladesmithing and have been relying on book knowledge and trial and error to learn. Some background. I'm from rural SW Washington with little access to knowledgable smiths out this way.. I tried to set up training classes with local forges up in the city but have been ghosted when I mentioned I was setting up my own forge. (Competition fears I suppose?) Either way my question is this.. I bought this nifty forge on Amazon and it came over stuffed with Koawool I trimmed it a bit to allow access to the doors once I added my Satanite.. but after taking the Koawool out and spraying it with rigidizer the wool collapsed and went from a fluffy 2" to a meager 1" ive been slow curing by putting the forge on my wood stove out in the shop over the past 3 days.. I know Insulsting properties are lost because of that.. is this forge still safe to use? I have caked the inside with Satanite to make the difference up.. as best I can but, I still want to make sure it's safe to use. Any tips? My goal is to use this forge to learn about hammering hot steele then upgrade once I learn the techniques needed to be proficient.. advise is welcomed 😃. Thanks all!
