Common Questions

Does silicone leach chemicals when heated?

Food-grade silicone (100% silicone, no fillers) is safe at normal smoking temperatures. Avoid unknown brands or products with strong chemical smell.

Can I use a glass ashtray for dabbing?

Yes, glass is heat resistant enough for dab tools and hot nails. Silicone can be damaged by direct torch flame.

How do I remove permanent stains from silicone?

Try baking soda paste, hydrogen peroxide soak, or denture cleaning tablets. Some discoloration may be permanent.

Is thick or thin glass better?

Thicker glass (3mm+) is more durable and stable. Thin glass breaks easier but weighs less.

The Verdict

For most home smokers: Glass is the better long-term investment. It looks better, cleans easier, and lasts forever with normal care.

For mobile smokers: Silicone is the practical choice. You can toss it in a bag, drop it without worry, and not stress about accidents.

Ideal solution: Own both. Use glass at home for the aesthetic appeal, keep silicone for travel and outdoor sessions.
