"Are glass straws safe?" We get asked this question a lot so it's about time we make a blog post about it.
Alright, let's start with what type of glass Seastraws are made from. The material is called Borosilicate glass and it's commonly used in oven-safe dishwares because of it's non-toxic and strong structure.
Most glass straws are made from borosilicate glass but what sets them apart is the thickness. If you buy cheap glass straws (from for example eBay) you will most likely receive glass straws with a thinner wall. Glass straws with thinner walls are more likely to break (I guess you don't need to be a genius to figure that one out).
We use a thicker glass for Seastraws to make them as strong as possible without being too "bulky". Compare it to your drinking glasses at home; Some of them seem to last forever while others constantly break. Seastraws are the ones that last longer!
To answer the question:
Are glass straws safe?
Yes and no. It all depends on what glass straw you choose. If you choose the cheaper ones you will have to take in consideration that they might break more easily. However, I've never heard of anyone breaking a glass straw with their teeth (yes, people have asked us this).
If you're comfortable drinking water out of a glass cup, you will most definitely feel comfortable sipping out of a glass straw. End of story!
