Even if it is only cracked internally, you no longer should use it as it could shatter.

I know. I no longer use it for that reason. I might turn it into boiling chips to get some more use out of it though.

Well I am currently at hospital waiting room with a few bits of beaker in my hand. Not too serious but a bit painful at the moment. Might need stitches. Certainly needs cleaning.

Full story of my stupidity later...

A couple of weeks ago I broke a thermometer well that I had forgotten on my bed after unpacking.

This weekend I did it again !
There was only a slight improvement with my procedure as I waited until morning to break the thing that somehow managed to stay with me all night.

Now I have 2 thermometer wells that I can repurpose...

That's a good possibility. In both cases I can seal in place some PTFE or VITON tubing to collect or bubble gas.

Well, the top front burner on my electric stove, is now shot.

Was I rash, in utilizing it as the heat source, for an impromptu furnace?

I was drilling holes, in what appeared to be 10lb cast iron weight disks. I have lots of extras.

Making ring stands I was.

Drilled my holes in one plate, tapped the holes, and put together a very stable ring stand.

Next plate, just wouldn't drill out. Too hard. At least, I think that is the problem.

Reasoning that the crap iron/steel must have been incidentally hardened by quenching, I decided to anneal the plate. Thereby making it drill-able.

Just put it on the front stove element, covered it with an overturned frying pan, and cranked up the heat.

After a bit, the plate acquired a sort of dull red glow, at which point there was a small explosion and a micro-fire at the base of the heating element.

I figured the "pop" might be just some cooking oil vapor "dieseling". No big deal. But, now my front stove element has become retarded.

Not heating properly anymore. Oh, well.
