Care & Glass vs Steel Source: https://phareros.com/learn/materials-ingredients/glass/ · Updated: 2026-07-02 Borosilicate glass is body-safe, non-porous, works with any lube, and is lovely for temperature play. ✓ Body-safe, non-porous ## The essentials - Tempered borosilicate glass — smooth, rigid and surprisingly sturdy. - Feels firm and glides beautifully with a little lube; holds warmth or cool. - Cleans completely with soap and water. - A favourite for firm, targeted sensation and for temperature play. ## Body-safe at a glance | Porosity | Non-porous | |---|---| | Phthalates | None | | Cleaning | Soap & water; boilable | | Sterilizable | Yes | | Lube | Any | **Good to know — porosity, safety & the honest detail** ### Is glass body-safe? Yes. Toy-grade glass is tempered borosilicate — non-porous, compatible with every lube, and it doesn’t absorb anything, so it cleans completely. It’s one of the safest, most hygienic materials there is. ### Can a glass toy break? Quality borosilicate is strong and handles temperature well, but it’s still glass: inspect it for chips or cracks before each use, retire it if you find any, and avoid dropping it on hard surfaces. ### How do you do temperature play safely? Warm it in a bowl of warm water, or cool it in the fridge (never the freezer). Skip boiling-hot or icy extremes, and always test the temperature on your wrist first. ## Glass vs Stainless Steel | | Glass | Stainless Steel | |---|---|---| | Weight | Lighter | Heavier | | Durability | Inspect for chips | Very durable | | Temperature | Holds well | Holds well | | Lube | Any | Any | | Allergen | None | Trace nickel | [Read about Stainless Steel →](https://phareros.com/learn/materials-ingredients/stainless-steel/) ## How to care for Glass 1. Inspect for chips or cracks before every use. 2. Wash with soap and water; 100% glass can be boiled. 3. For temperature play, warm/cool gently and wrist-test first. 4. Store padded and separate so it can’t knock against anything. **For the material nerds ↓** Borosilicate glass adds boron trioxide to silica, which lowers thermal expansion (the Pyrex family) so it resists thermal shock — why it tolerates warming and cooling. Its surface is a smooth, non-porous amorphous solid, and toy glass is annealed/tempered for strength. It’s chemically inert, so no lube or cleaner degrades it.
