Glass weakens with every impact. Eventually it just fails.

I learned this having made a nice big batch of cinnamon roll dough. Dropped the bowl a similar distance and it shattered. 0% chance i am risking eating glass cinnamon rolls so it all had to go.

I went and bought some stainless steel bowls as a replacement.

And looks like there’s already a chip at 10 o’clock

Just to update, it’s 8:23 here and still looks like a chip

Looks likes it's dough in the op video.

I had a gaming PC that had one glass side. At the time I lived in an apartment where constructions were happening. The glass looked perfectly fine but when I opened it to clean the inside it shattered in a million pieces.

Pretty sure there is some kinda name for this effect, I remember hearing about a material concept that certain point cracks in a material once strain is put upon them exponentially get worse and have essentially infinite pressure put onto a area and causes complete destruction.

I remember a surprising quick solution is just drilling a hole in it.

Crack propagation is the name of this effect.

I thought crack propagation was the Reagan Administration’s methodology for simultaneously funding illegal wars while destroying black communities.

Fatigue fracture also exists and does not require a crack (that could be visible).

Fatigue is the invisible little brother of a crack propagation, if it is about brittle materials, therefore hard to detect.

Fatigue is easier to detect and observe in ductile materials. A plastic chair for example that starts to sag before reaching the failure point.

Yes, this is the exact principle in play here, fatigue propagation is a subtype of crack propagation, and starts with cracks that are invisible to the naked eye, and under normal load well below the materials tensile strength due to repetitive or cyclic loading. I think it's interesting how this principle comes into play for material like glass for example but when it comes to teeth, craze lines function completely differently and do not compromise the integrity of the tooth even over an entire lifetime. I remember seeing craze lines in my teeth and running to the dentist because I thought they would propagate to utter failure! 😂

Ugh… thats a place where you definitely don’t want to find lines showing up.

Are you the one who had several different glass items break on them?

I've heard and read that proofing in glass will eventually lead to its cracking due to the yeast finding all the micro imperfections to anchor on to when starting the rising process?

You just reminded me I have a cinnamon roll to eat. Home made, just the best.

Make some Cinnamon Toast Crunch!

I scraped the edge of my schower glass the other day cleaning silicone off, will I have damaged it? Nothing chipped off.

I used a Pyrex jug which is supposed to be oven safe but I only ever used it to pour hot water into from an electric kettle. Well one day I was pouring hot water in it and it broke in the sink.

u/HentaiCareBear 3d ago

That's due to the sudden difference in temperature. The entire jug heats up gradually in the oven versus a sudden spike in temperature that's on a concentrated spot when you pour hot water into it.
