Cast iron humidifier

[Bristlecone]

Have a cast humidifier pot and would like to keep it. Problem is, it’s rusting through the outer glaze, pinholes and a bit larger. Any ideas of sealers or inner coatings I can use ?

These should do the trick to seal the bad areas on the inside.

I use a lot of jb weld. Did not know they had a high temp. Thank you amigo.

Would never use extreme heat jb again. It doesn’t grab, it doesn’t have an enamel finish, it’s flat, shrinks and flakes at the edges.
I liked the consistency of the high heat, especially for the bottom. Very liquidy ( if that’s a word ).
Next time, I will use only jb original, although long term results aren’t in yet. It’s cheaper and can withstand a constant 500 dgr.
Our humidifier sits on a trivet. I can’t see it ever reaching over 230 degrees. It gets hot but can be barehanded briefly. Like, real briefly.

Pic 2) is the rusted pot. 3) is after using a wire wheel. 4) is the fancy barbecue motor assembly converted to a humidifier turner. Used it to prevent the epoxy from sagging. We are on cutting edge of technology around here. 5) is the reason I’m trying to repair this , love it. 6) is where it sits

That humidifier is cool. Is it brown enamel? Is it vintage or fairly new? I'd like one similar at some point

It’s about 15 years old. I thought it was porcelain finish but it seems to be an enamel. Money was tight at the time, but paid $130 at the local wood stove store. Couldn’t walk away from it. Got it home and found out it was made in china. 2nd pic is the finished bowel.

This. Is my other one. Wife found it at an antique store 40 years ago. It’s hammered aluminum and will last forever.

Thanks for asking

China, well it's still cool. As is the hammered aluminum kettle. What is the inside of the bowl coated with? Is that the jb weld from above?

Is this one similar?

Bear Humidifier

it says porcelain, but I don't like the matte black

Is yours stamped with a JW on it?

 

[Bristlecone]

Yes, it is stamped John Wright. I never really paid any attention to that. My, you really do your homework.

The first layer on the bottom was the 1000 degree jb weld. But it shrunk and flaked around the outer edge. It didn’t seem trustworthy. I ended up chipping away the perimeter flake and added a full layer of original jb. That coat did not pull away.

The internal sides took 4 tubes of the high heat jb, 550 degree. So, I end up with 3 different epoxies, and 3 different colors. It is somewhat comical. It wasn’t my intention to use 3 varieties. You know how it goes, order 1, then maybe this one is better, so get that one also. Then research and find a mere 50 degree difference with the jb original, so add that into the project. The bowl still has not fully cured.

The Amazon one; I dono. Never seen “flat” porcelain. Might be fun to try and paint it.

Thanks! I had actually been looking at the John Wright pieces for a while. I'm torn between them and something antique / vintage. I do like the bear and there is a moose too. The moose is a little over the top for my liking buy cool none the less. I have a brown Hearthstone Shelburne stove on order and I would either match or contrast that color. Hopefully I can get it installed before the tax credit expires.

Let me know when the jb weld cures up. Interested to see how long it takes. I do have an eye on one that has some rusting inside the bowl, so likely I would try something similar if that works for you.

I let it all cure for 5 days, but it never got the slippery finish. Spent an evening putting it on the stove and removing it when it got warm/hot. It did have water in it.

The bottom buckled up about 1/2”, remember that was the extreme heat JB, so I broke it out and will use original formula JB.

I originally coated the side wall first. Some it dripped to the bottom, before I could get it mounted onto the motored turning system. It has a very solid grip.
