Borosilicate Glass Candle Vessel
As part of the brands commitment to zero plastic in our products and packaging. We wanted to develop a new candle vessel that not only had an elegant glass design but could also be easily recycled and reused after the candle was finished.
By using Borosilicate glass for our new vessels, it has a very low coefficient of thermal expansion, meaning it expands and contracts very little when heated or cooled. This low expansion makes it highly resistant to thermal shock, which is the tendency for materials to crack or break when subjected to rapid temperature changes. Making it ideal for our candle vessels.
Why Borosilicate Glass
Many companies choose to use soda-lime glass for their glass products because it is less expensive and readily available. It accounts for 90% of manufactured glass worldwide and is used for items like drinking glasses and windows. Soda lime glass is susceptible to shock and does not handle extreme changes in heat. It’s chemical composition is 69% silica (silicone dioxide), 15% soda (sodium oxide) and 9% lime (calcium oxide). This is where the name soda-lime glass comes from. It is relatively durable at only normal temperatures.
Borosilicate glass has a much higher proportion of silicon dioxide in comparison to regular soda lime glass (80% vs. 69%), which makes it even less susceptible to fractures or cracking in changes to temperature, making it more durable.
It is completely recyclable and can be reused, contributing to sustainable manufacturing practices.
