No they won’t. They are made out of borosilicate glass, the same type of glass used for glass cookware, which is much stronger then soda-lime glass that is typically used to make glass bottles and drinking glasses. They are also annealed in a kiln, which strengthens the glass.

Unfortunately no, they are not unbreakable. They are made out of glass and can be broken with enough force, like dropping on rock or concrete. They can also chip if dropped on a granite or tile counter. Extreme temperature changes can also break them, such as going from being in boiling water to cold water, or from the freezer into hot water.

The word 'Pyrex', although a current brand, has become a generic name for borosilicate glass that is resistant to heat, chemicals, and electricity. It is used to make quality glass ovenware, and microwave safe glass. All of our items are made out of Borosilicate glass, the same type of glass as Pyrex.

At this point in time we do not take custom orders. We do however have more variations then are listed on the website at any given time. If you are looking for a specific color, design, or feature, and you don’t see the combination you want, please let us know. We will check our current inventory and let you know if we have anything that is closer to what you are looking for.

We recommend using soap and warm water. Make sure to completely rinse off the soap so it doesn’t irritate you the next time you use it. You can also wipe it down with rubbing alcohol, and rinse with water. Or you can put it in the top rack of your dishwasher (run it without detergent, or rinse it afterwards to ensure no detergent residue is left on it.).
