Orcoroc tempered glass anomaly!!
Don't know where, exactly, to post this - but some may consider arcoroc French glassware collectible, so I'll try here first.
Ok... I "had" a set of 4 glass mugs, got them at GW years ago. Tempered glass, clear w/no color or tint. Into one, I'd put unpolished rock stones from DH's kit. (They've been kept there for several months, in a cupboard). Decided to rinse any dust off, before putting them into polisher. They were rinsed w/water, then DH put a bit of dishwasher detergent in & swished. ALWAYS with room temp water!
This morning, around 10:00 am, he drained all water out & set mug to side on counter. About an hour ago - it SHATTERED, nobody within 7 feet of it! Completely freaked us out - I was upstairs & heard it.
More weird... It kept "popping", for at least 20 minutes - little chunks of glass jumping around like jumping beans!
Most weird... While we stood there watching, in dumbfounded shock, talking about possible causes, I asked DH "um, you don't suppose this is supernatural, do you?"... He said "No, there's got to be a logical explanation!". (He's my lovable Spock, lol). Then, he reached over, picked up a piece of glass & instantly dropped it! It shocked him, as in "electrically"!
I actually took video with my phone, & think I caught a pop & piece of glass moving. Here is a photo I took a few minutes ago - around 9:45 - I heard another "pop-crackle" as I took it.
I put one of the other mugs behind the rubble, to show what it was before.
Anyone able to explain this? NO temperature change, no activity around it for hours - help! I'll post elsewhere, if I get a rational explanation I'll share it, here.
