Well, see there. You have brought up something I haven't thought of yet. I'm not educated on cold packing, except that it usually means raw. If it has more meaning than that, I'll have to investigate. I'm pretty sure it was cooked and she never had a "canner" either. I just remember everything they canned was the only way I know how.
On another note. I already made the mistake with Lima, are you male or female?
Cold (I think what I really mean is called HOT pack) pack is the jars are completly immersed in water and boiled..not sure how long but think greater than an hour.
Everything had to be sterile! Rings, jars, lids, spoons, tongs, whatever. Time depended on what was being canned (acidity). Obviously green beans were boiled longer than other foods. You have to know what you are doing, if incorrectly done, food can spoil, you can get food poisoning, etc. Probably one reason Southerners eat vegetables cooked so long. Open the jars and cook long enough to kill the salmonella

. I've done what I think they called cold pack, high acid like tomatoes. Also made homemade jellies, jams, syrups, etc. Never trusted myself enough to try anything low acid/hot pack. My mother was old enough to be my grandmother and I was the baby of the whole family, so I only got in on the tail end of stuff, never really participated or learned very much. But it was not pressure cooking I'm sure.
Female...it would take a very brave and self assured man to use my VN name and have a decked out toy poodle for an avatar

. But in her defense, she offers to fight the pit bull. She's 4.5 pounds of sheer meanness!
