What do you guys use for a container for cold treatment using dry ice and acetone/kerosene/denatured alcohol?
 
I used to use an aluminum tea pitcher. Doesn't break or dissolve. Any metal bowl or bucket should be okay.
 
My problem is that I would be doing kitchen knives which means total length up to say 17 or 18 inches for a big slicer.
 
Aluminum baking pans come that big but take a lot of slurry to fill up..Ive planned on making a nice tall metal cylindrical container for a long time but have never got around to it..whenever I come across some nice aluminum or stainless pipe ill snatch it up for the purpose.
 
I personally like the kroger brand plastic tubs in the largest sizes and they have a lid so I can leave my alcohol sealed and on the shelf when not in use.

Let use know if you come up with something slick!

I use a welding rod canister, one that's full length with a plastic snap on top.
Since you're treating the cutting edge, or ideally the blade, and the handle doesn't really matter, that's plenty for all the cooking knives I make.
 
I had to go to smart and final to find dry ice locally, while I was there I found a Teflon coated baking tin that was $4. Saved a lot more that $4 worth of grief from the wife. Just know that it will freeze whatever it's sitting on.
 
I use a 1 liter plastic soda bottle with some 1/4 inch holes drilled through it. I set that inside a platic bucket. The dry ice goes around the outside of the liter bottle the rubbing alcohol goes inside.
 
I use an insulated Thermos brand cooler similar to this one.

I use a stainless steel "whole fish pan", AKA a "Fish Poacher". It is 18" long with a rack to lift the blades ... and has a cover. A similar looking item is an autoclave pan. Fish pans cost between $30 and $40 new, but can be found at junk yards and yard sales for as buck.
 
I,m in Lo/Rez camp on this, a cheap walmart cooler.It'll hold for 24 Hrs.Some people like to add a sub-between tempers.
 
I just recently used dry ice for the first time and I used a 50cal ammo can. It works well and seals up nicely too so you can store the acetone in it. Although, I think Stacy mentioned it before, but I leave the lid open for a few days to allow any residual CO2 to leave the acetone before sealing it up.

Made myself two, one larger and one smaller out of U shaped stainless steel, had to weld the sides. I bought the stainless at a scrapyard.

Here is the smaller one
