Yeah, that is weird...
Here's a copy/paste of the blurb...
CAUTION! Don't Be Tempted to Recycle an Old Crockpot for Pickle.
Updated on Sunday
... For any length of time, at least.
I didn't need this crockie anymore, so I used it to pickle my entire stash of glass rods.
Worked a treat - just needed to turn the bundles so both ends got a cleaning.
I figured that since the pickle would last for ages, I'd just leave it all in there until I needed to do more glass.
That was about six months ago.
This week I discovered a mineral deposit on the desk where I'd stored the pot.
Looking a bit closer, I realised what had happened. The crock was quietly seeping!
Sure enough, there were hairline cracks in the crock which allowed a very slow drip of pickle through the ceramic, and into the bottom of the cooker body. Worse, it was leaking out via the power outlet.
The photos show the damage and the effects. And the last shot is the aftermath of the baking soda reaction while getting it ready for disposal.
That stuff, after all this time, was still extremely potent.
