So, it looks like I'll be canning...where can I find the supplies to can?

Be aware that all the salt in Argentina has Iodine added by law. Not ideal for pickling.

Yet they do produce pickles and canned goods in Argentina with this known (known to the rest of the world) lack of quality in the taste of preserved foods.

Some quick research, you are referring to the 1967 law Ley Nac. N° 17.259 link argentina.gob.ar

2021 resolution might aim to address this issue. I do not understand if this is now in effect or it is a proposal. One of the articles states something like this: "if it does not have iodine, whether for human consumption or not, then it must be labeled for industrial use".
- here is a news article summary translation The Government modified the quality standards for table salt

You can buy "Sal Rosada Del Himalaya" on ML where the vendor claims it's not iodized. It's what I use, but I don't know more than that.

Can be purchased at any forrajeria farm supply/animal feed/pet feed store. Any bazar home and kitchen supply, or most ferreteria hardware store. Now there are many brewing supply stores where more specialized things can be found.

Unfortunately there is no standardized system of ring/band and BPA-free seal system from USA brands like Ball in USA. Jars are easily reused, though best practice is to always buy fresh lids. I like the wide mouth jars 660ml which is the same some grocery products are sold in, but also new at the forrajeria, etc...

Tall cheap aluminum pots Olla Aluminio Gastronomica 30lts or more for water bath. Search Mercadolibre to get an idea on best height and width.

I still cannot find good tongs which are specially designed for lifting heavy jars from the boiling water.

These jars are like the ones in the us, the lids have 2 parts. magnetics wands don't exist here. They are not cheap.
