TnAndy just posted a post on canning grape juice with some old canning lids. While the experiment is still in progress, I would love to hear other members success and "failures" with long term storage items. I know some things, hand tools, saws, axes, knives, are useful for 100's of years, but the gasoline formulation that I used to store, pre alcohol, for 5 years or more in a cool dry place, won't last longer than a year or so with Stabile for an additive and I don't really know how long it would last with Pri G. BTPost tells of burning WW2 diesel that was stored in 55 gal drums. That was the old formula, no alcohol, straight run from the refinery. What has experience been with new diesel in contrast? Looks like temp has a lot do do with keeping it usable as well as preventing oxygen from interacting with it. In the real world what has peoples experience been with successful crops from seeds stored for an extended time. did the ones put up for long term storage do better, ones stored in the freezer. Most of the data I see is spread all over the net and tends to either be done by someone selling something or a scientific study based on food found stored in some ones basement. I have fired WW1 Turkish ammo up until about 1990. If stored properly, at least that was my guess, as some lots worked really well and some did not. I still fire WW2 US, German, and Russian ammo with good results and if SHTF would feel safe using it. Given its corrosive, you have to clean at once to protect your firearm. I fired my great grand fathers civil war musket with caps and cartridges from the end of the war or so. Still worked fine in the 1940's. Have 20 plus year old powder that I use in reduced loads for target practice in center fire weapons and they still work fine for that. Don't know if I would trust my life on it however. Chickens have loved 25 year old stored grain and 10 year old nuts packed in sealed pouch with oxygen absorber and it doesn't seem to bother them. Have oil based paint stored in a full sealed can that I used that never froze or got hot that was usable 20 plus years later. New Latex seems to go bad in about 3 years, but it might be my storage. I have burned lamp oil from a full sealed glass bottle that was stored in the basement for 30 years and it was fine, however as other lamp oil or kerosene, in a couple years in the lamp it will go bad or at least discolor. Easy to see in glass lamp, but not so easy in a railroad or barn lamp made of tin. Wool blankets, shirts etc would seem to last 100's of years, leather shoes, rubber boots, aritic shoe packs, etc, haven't worked out well for me, leather seems to do better if treated every couple years and rubber just seems to get hard and brittle what ever I try. Has anyone else had long term foot ware, 20 years or so success, I haven't. How long do the rubber seals for the pressure canner last in the real world, both in use and in storage. Once they are gone you have a very expensive heavy pot instead of a pressure cooker.
