Comparison
Silicone vs glass dildo.
Two of the four genuinely body-safe dildo materials. Silicone is forgiving and flexible; glass is rigid, takes temperature beautifully, and is the easiest to clean. Most experienced collectors own at least one of each.
| Spec | Silicone (platinum-cure) | Borosilicate glass |
|---|---|---|
| Flexibility | Flexible, soft skin-feel | Rigid, no give |
| Temperature play | Body temperature only | Excellent — warm in tap water, chill 10 min in fridge |
| Compatible with water lube | YES | YES |
| Compatible with silicone lube | NO — bonds | YES |
| Easy to clean | Soap+water; boilable | Soap+water; dishwasher-safe (top rack) |
| Lifespan | Decades | Decades (drop-resistant but not unbreakable) |
| Best for | First dildo, partner play | Sensation play, temperature, experienced collectors |
| UK price range | ~£25–£100+ | ~£30–£80 |
The verdict
Buy silicone first — it is more forgiving, suits more positions, and is the universal default. Add glass as your second material once you know what shape you like. The two complement each other; they do not replace.
