Look what melted instead.

Glass should not melt like that... shattering glass happens because of sudden temperature changes like setting a hot glass bowl on a cold counter. I would look at the microwave but I wouldn't use the microwave because they tend to create hot spots. If using the microwave stir often.
 
I always put a little of my soaping oils with the steric to melt it, but didn't do it to keep the glass pitcher from melting. Thanks for posting this, it helps make us all aware of what could happen.
 
That's really bad, I would contact the manufacturer and complain as if it had melted further down you could have been badly hurt.
 
I quite melting my stearic in the microwave as it just seems to take too long and anything I put it in get so hot. I generally put it in my mini crockpot or over a double boiler. Sorry that happend to you but the just don't make things like they use to thats for sure.
 
Newbie said it was a Pyrex measuring cup, which is glass (what flavor may be under debate, but it's definitely glass, not plastic).
 
Melting point of pyrex glass is about 800C. Regular glass in eg. drinking glasses is about 1500C. There are a few types of glass with what is considered low melting points, about 500C, that are used in residential windows. Nonetheless, those temperatures can not be reached in a household microwave. A glass can shatter in the microwave due to material fatigue but it will not melt. Hence, regardless of how it is labelled and sold, the pitcher on the photo is not glass.
 
I had read somewhere that glass can melt in the microwafe and the producer has a lot of problems because it happens. Contact the factory, it is shoking
 
It's glass, 100%. It is definitely NOT plastic. I could shatter it to prove the point but I'd rather not. Plastic doesn't clink like glass nor feel like glass. Plus they sell it as glass.

I did send a message to Anchor Hocking but I haven't heard anything back after a couple days. Not impressed with that.
 
Well, there is certainly no question about glass or plastic. I put it through the dishwasher and it exploded during the cycle. Now I get to pick small pieces of glass out of the bottom of the dishwasher and out of the drain/filter thing at the bottom. Should be fun.

THere's the spot by the handle where it started to melt, and there are the shattered pieces.

I had a bowl break while it was in my hand but it didn't explode. I just ordered some lab glass borosilicate beakers from American Supply and SUrplus (i think that's the name). I got 2 2000ml ones and some 600ml ones. I thought about the 1000 ml one but I usually make 40 ounce batches and that would be just too much for a 1000 ml beaker. I was actually happy to pay $18 for the huge beakers and the smaller ones were just under $6. Fine with me so I don't have to worry.

I must be blind. I looked on sciplus and didn't see borosilicate beakers but I saw the graduated boro mugs. I went and looked again and found the beakers. http://www.sciplus.com/p/BEAKER-250ML-HEAT-RESISTANT-GLASS-78MM-X-124MM_274

I'd love to get some boiling flasks just so I could feel like a mad scientist.

@ Saponista -

That's a nice site. I noticed the distillation glassware and wondered if you could make your own essential oils with it.
 
Yep, that's the place I ordered from. I had to laugh at your post, Hazel. I had a 1000ml round bottom boiling flask in my cart until the very end, just because it felt good! And they have those long necked round bottom flasks with ground glass stoppers too; that was extremely tempting, but I forced myself to be practical. I just pictured making soap in it and having it accelerate, then not being able to get it out.
