Borosilicate glass is a strong, heat-resistant glass, the same type used in laboratory and kitchen glassware. In sex toys it is used for dildos and plugs because it is non-porous, very smooth and easy to keep clean. It can be warmed or cooled in water for temperature play, and it works with any type of lubricant.
Why it matters when buying
Glass toys look fragile, but borosilicate handles knocks and temperature changes far better than ordinary glass. The things to check are that it is solid borosilicate from a known maker and that it has no chips or cracks.
What to look for
- “Borosilicate” named on the listing, not just “glass”
- Check for chips before every use and retire a damaged toy
- Warm or cool it in water, never in a freezer or microwave
- A flared base on any glass toy used anally
