got my omegaclad thermocouples, 24" x 1/8" K type, and melted about an 8" column of salt in the 304ss tube I got from Darren Ellis (4" x 24") Took it up to 1830F, but temp was climbing fairly slowly at that point, and I only need 1550F for the moment, I may mess with stainless or hss later.
Anyway, poured the salt out into another stainless container, cooled it, and busted it out. Here's a few pieces, I'm wondering what the blacks, browns, and grays are. The salt is a 50/50 sodium & calcium chloride mix. The inside of the ss tube was looking a little ugly from melting some salt before, so I'm guessing a lot of the coloration was scale and contaminants on the inner surface. Should I expect anything different when I run a full tube?
The pieces are nice & shiny because the salt soaks up moisture like a Hoover and I'm in bayou country
