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.
