Sustainable Glass Drinking Straws – FAQ

FAQ on the Care and Feeding of Glass Straws
Q: What is borosilicate glass?
A: Borosilicate glass is a specific type of glass, the same glass you may know as Pyrex, which was created by Corning. Borosilicate glass, or “boro” for short, is made with the silica and boron oxide. Borosilicate glass is most well known for having very low thermal expansion, making it resistant to thermal shock, more so than any other common glass. What that means is, it doesn’t break easily, which is why it is used in glass cookware that goes in the oven, microwave, and dishwasher. It is also a non-porous and Hypo-allergenic material, which is why it is so safe for food use. Borosilicate glassware has increased durability and has microwave and dishwasher compatibility over other types of glass.

Q: Can you make a special size straw for me? I have this favorite tumbler I use…
A: Yep! I can. I can tailor make a straw to your desired length, width, or even thickness of the straw wall. Please email me at with your specifications and I will contact you.

Q: Will my straw ever break if I put it in the dishwasher?
A: Nope, unless you are throwing it in there with hurrican force! Straws will easily withstand dishwasher and even microwave use, just like Pyrex cookware and dishware. We recommend sanitizing your straws in the dishwasher to help keep it clean. This sort of use and cleaning is normal use, and your straw will not break under normal, everyday use.

Q: What if my straw gets a crack, or chips?
A: If you ever notice any chipping, cracking or breaking, stop using the straw! If it is dropped there is a possibility of chipping or breaking. It is, after all, glass, even if it is some of the strongest glass on the planet. Email us at: to let me know. If I cannot repair it to original condition when you return it to us, I will gladly replace it free of charge, including shipping. I guarantee the life of your straw as long as I am working in glass; if it breaks, I will gladly replace it for you.

Q: How do I get a refund if I am not satisfied with my glass straws?
A: Email us at: if you are not satisfied with your straw. We will issue you a refund for the total amount of your purchase (excluding shipping).

Q: My straws have become opaque and dingy looking, what can I do?
A: Think of your straws like other glasses in your dishwasher. Over time they can become more opaque due to the minerals in your water supply. If your glass drinking straws become “cloudy” from hard water conditions in the dishwasher, simply soak in distilled white vinegar. Another tip for cleaning is to rinse them right after use, keeping them crystal clear and clean. If that doesn’t work, use a pipe cleaner or a baby bottle brush to help clean out the inside.

Q: Can my child use your straws?
A: I recommend glass straw use only for kids 6 years of age and older. They are fun and pretty, but I would hate to have your child accidentally chomp down hard and hurt their teeth, or their mouth, even if the straw didn’t crack! Use good sense and teach your children about how to use this straw. Then they too can contribute to creating a cleaner, greener, healthier world! Not to mention being the hit of the lunchroom with their cool straw!

Q: Do you wholesale?
A: Of course! The more folks use glass straws, the less plastic straws are “needed” to be made! Email me at for wholesale pricing.
