  2. Here in the United States, whenever I find the PYREX with capital letters in the resale or thrift stores I try to buy it because it's made of borosilicate glass. The new pyrex glassware with the lower case letters Is made of cheaper soda lime glass that can't take anywhere near the same thermal shock which is what you need if you're going to be cooking in it.
    It's sad that overseas they still make it out of borosilicate glass, but here we can only get the cheap stuff new.

  3. Are you sure you did your research properly? Because the original Pyrexx with a capital P made by corning ware so the rights to another company who can market Pyrex with a lowercase P, which is not as durable.

  4. I rarely disagree with ATK, but soda glass can take knocks and hard bumps more readily. Borosilicate glass is better with thermal shock. I have a full set of borosilicate in my kitchen for specific uses on the stove but have broken them with little effort at room temperature comparative to today's pyrex glassware. Choose accordingly.

  12. Back in 1962 my gramma dropped her large Pyrex bread bowl. She would use this bowl to make triple batches of bread. When this bowl hit the kitchen floor it shattered into a million pieces. Back then we wore dresses so when the Pyrex shattered it sent splinters flying into our legs. Gramma couldn’t get the splinters out of our legs so we went to the hospital to have them removed. It took over 3 hours to get them out. When we were done they put iodine on our legs. When the Novocain wore off, WOW! It was over a week before our legs felt somewhat better. The splinters they missed took over a year to come to the surface so they could be removed. Gramma went out and bought another Pyrex bread bowl. When I grew up ~ No Pyrex for me!

  15. There's 2 different materials used depending upon whether Pyrex uses capital letters or not. Lower case letters use soda lime glass but the version using capital letters is still boris silicate.
