Have an All American 915 canner. This is a made in Wisconsin, all aluminum – milled out of a solid block of aluminum – canner. No gaskets. Heavy as hell, takes forever to cool. and there is no way, no matter how bad it gets, that this canner will explode. okay, put explosives in it . . . the walls are thick and the lid is clamped down with 6 separate screw down clamps. Has a pressure gauge as well as a “jiggler” set for 5 – 10 – 15 lbs.
And mine has been leaking steam through the lid.
and it seems the answer, which I still have to check out, is simple!
FIRST – a PHONE CALL from the customer service rep at the Wisconsin Foundry. Yes, an real live American, from Wisconsin, on the phone, rather than an e-mail. Tells you how bad things are that such a call totally makes my day!!
So it seems that Vaseline is OUT as a lubricant for these canners and Olive Oil is in. a couple of reasons for that, and one is that the Vaseline will stick to the surface and harden giving an uneven sealing surface. A red scotchbrite pad is the recommended cure for that. Be sure to NOT sand down the sealing surface unevenly – then nothing will help – this is just to clean it up. Then Olive Oil. will have to buy a cheap bottle for just this purpose.
Not that I’ve been without a canner, but there is something about that 915 that’s special!
