Velasca Water Set
Not to get all Science Fair on you, but borosilicate glass is made up of about 15% boron trioxide, an ingredient that changes the behavior of glass and makes it thermal shock resistant. This allows the glass to resist extreme changes in temperature—it can go straight from a freezer to an oven without cracking and withstand temperatures of up to 932 °F. And so, this glassware can be used for both hot and cold beverages. Imagine serving hot chocolate with this set!
Using borosilicate glass leaves a low carbon footprint as it is made from naturally abundant materials and does not require excessive mining. If handled with care, borosilicate glass will last a lifetime.
