HOW TO TELL IF PYREX IS BOROSILICATE
You can tell if pyrex is borosilicate by following the steps below:
Calculate the density manually.
- Calculate the dish’s length, height, and width.
- To calculate your volume in cubic centimeters, multiply all three measures together.
- To determine the mass, weigh your dish.
- Calculate your density by dividing your mass by your volume.
You most likely have borosilicate glass if, after calculation, the density of the glass is 2.23 or near to it. However, soda-lime is present if the glass has a density of 2.52.
Looking closely at the color is another way to determine whether pyrex is made of borosilicate. It is soda lime if you see a bluish-green hue. There is no color in borosilicate.
BOROSILICATE GLASS VS PYREX
Pyrex and borosilicate are often used interchangeably. However, they do share some qualities and characteristics. Borosilicate glass vs pyrex–
Initially made with borosilicate, soda-lime glass is now used to make pyrex. A mixture of silica and boric oxide is used to create the low-melting glass known as borosilicate.
Borosilicate and pyrex are subsets of each other in terms of thermic properties and low thermal expansion. In addition, they are used in cooking.
While borosilicate has a greater melting point than pyrex, both materials are safe as long as the temperature is not surpassed. Pyrex can withstand higher temperatures.
Boron is more resistant to thermal shock than pyrex, which no longer possesses this characteristic.
