Hard to find new Cast Iron Pressure Cookers for use with Caustic Soda. Aluminum pressure cookers are a no go, but most Autoclaves are Stainless Steel. Anyone Have Experience using them with Lye?
Better yet, if you have one to sell new/used, and have personally tested it with caustic soda, at 250F+ then will buy from you at 500usd for cast iron or 1k usd for all stainless.

what are you doing exactly? can you not put the caustic soda within another suitable container in a PC with water in it?

Thanks, your double walled solution will work but will require a bit of welding work. Although seems wise to replace the smaller cast iron after x uses just like graphite crucibles instead of the stainless.

What are you doing with lye in a pressure cooker?
Earlier today I read that lye is very corrosive to SS at boiling temperatures, so that's not a good idea. I would guess similar for cast iron but not sure.

I was thinking of plastic or maybe glass containers.
If you gave more info you might get more help.
