I've had jars bottom out on me like that a couple times. Fortunately it was in a hot water bath both times so it all just dumped into the water. I stopped doing hot water baths after that second time. Then I stopped using lye altogether and went to the drytek.

A story of one my many fails:
I had a jar of spice infused solvent evaporating in front of a fan. Full extraction, probably 1.5-2 grams worth. I wanted to speed it up so I set the jar kinda on it's edge and made sure it was well supported so it wouldn't roll around or spill. Well, I accidentally bumped the table and watched as the jar tipped rolled and dumped my whole extraction into my cork yoga block which was conveniently sitting right below the table. I was bemoaning my fate in chat about it and House was like, just think of it this way, every time you do yoga now you'll reach for your block and know hyperspace is right there with yoyu. Now every time I'm doing yoga and reach for my block I crack a little smile an remember what is sitting right behind the veil.

Don’t forget:

The famed professional chemist, Albert Hoffman, while working with as of yet unknown molecules innhislab, was careless enough to accidentally ingest a biologically active quantity of one of these molecules.

Even the pros mess up.
