Made from BOROSILICATE GLASS - the strongest glass commercially available.
Borosilicate glass is a type of glass with the main ingredients of 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. It is also non-porous and Hypo-allergenic. Borosilicate glass was first developed by German glassmaker Otto Schott in the late 19th century. Borosilicate glass is often used for high-quality beverage glassware and kitchenware (e.g: Pyrex®)

We adhere TO A FORMULA provided by Corning, Inc. for annealing our straws under computer controlled conditions. The temperature and ramping rates dictated by this formula are crucial to reducing residual stress in the glass and give it the highest possible levels of resistance to thermal and physical shock. 

Design & technique is crucial!
It is important for the durability of a straw- if glass is fused together in such a way that it creates a fold or groove, it creates a weak point – an invitation for breakage. Fusing technique is also important in the durability of the straw (i.e. adding a dot to the straw.) If both pieces of glass are not hot enough, the result is an inferior joint and susceptible to breakage. Not all designs lend themselves to proper fusing. The time required to do this would dictate that the price of the straw would be higher than it would reasonably sell for.
We take great care during the development of our designs, our production processes, the monitoring of our kilns and quality control procedures making our straws the most durable on the market. This is what defines us as the industry leader.
