Pyrex is not Damon Proof Certified

[Nomad74]

Working a urine job today. I dip my measuring cup into my 150 degree osr bucket and hear a "Pop". Lifted out my Pyrex cup and sure enough it had cracked.

I always thought Pyrex was supposed to be able to handle heat. Guess not. Thermal shock.

Not Damon Proof.

How hot is $150 degree?

150° is hot enough for your DAP.

Send them a pic. Maybe they will give you a contract to test their cups and certify them.

Hell, I couldn't even get the Excellent Supply guy to send me a test sprayer. Vendors fear me.

I fixed the typos. I was waterclawing while posting.

Pyrex is now made in China. It is garbage.

Go find a REAL Pyrex cup made in the USA, perhaps at a thrift store. It will not pop.

Damon would leave it on the bumper so it could shatter on the pavement at 70mph.
