2-4 Material Matters for Coffee Brewing Equipment!

You probably own some coffee brewing equipment at home and brew with them everyday, but how well do you know about the different materials found in these gadgets? Some common materials are glass, stainless steel/metal, and plastic, which are also found in Ovalware's Cold Brew Makers. Here are two quick questions about some of these materials:
1. Do you know the difference between borosilicate glass and other glass? Why do we choose this particular glass to make our Cold Brew Maker?
2. Do you know the different stainless steel grade, for example, the 18/8 304 that we make our Cold Brew Maker with?
If you have no idea what we are talking about here, no worries, just read on.

 

BOROSILICATE GLASS

This particular kind of glass contains 15% of boron trioxide, an ingrident that alters glass behavior by making it thermal shock resistant at a maximum of 170°C (about 340° Fahrenheit.) Traditionally used in high-end restaurants, laboratories, and wineries for its purity and durability, borosilicate glass allows you to pour boiling hot water into The Cold Brew maker without worrying about shattering or cracking.
Through superior resistance against chemicals and acid degradation - there’s no more need to worry about harmful chemicals and unwanted metallic or plastic tastes seeping into your brew. Just FYI, this is also the type of glass for storing nuclear waste, and tends to last a lifetime.
It is also dishwasher safe, allowing you easy and convenient cleaning.

 

18/8 (306) STAINLESS STEEL

'Stainless' steel (s/s) isn't completely stainless, but only stain less easily compare to other type of metal. Stainless steel contains at least 10.5% chromium, and the percentage increases with different grades.
Ovalware chose 18/8 304 grade s/s, containing 18% chromium and 8% nickel, to make most of the brand's coffee equipment, giving the products beautiful and clean finishes, and is easy to clean. The 304 s/s can withstand corrosion from most oxidizing acids, making it an ideal and common material option for kitchen appliances.

---------------------------------
