Frequently Asked Questions About Cannabis Accessories

What size bong should I buy?

The best size depends on your experience level and preference. 12"–14" bongs are great for beginners and casual users β€” compact, easy to clean, and portable. 16"–18" bongs offer longer smoke paths for cooler, smoother hits and are popular with experienced users. Browse our full bong collection to compare sizes.

What is borosilicate glass and why does it matter?

Borosilicate glass is a premium, laboratory-grade glass that contains boron trioxide, making it highly resistant to thermal shock and breakage. Unlike cheap soda-lime glass, borosilicate won't crack from heat or sudden temperature changes. All Castle Glassworks pieces are crafted from borosilicate glass for maximum durability and a cleaner, purer flavour.

What's the best cannabis accessory for beginners?

For beginners, we recommend starting with a 12" beaker bong for a classic, easy-to-use experience, or a quality 4-piece grinder as a foundational accessory. Browse our Beginners Collection for beginner-friendly options.

What is an ash catcher and do I need one?

An ash catcher is an add-on glass accessory that attaches between your bong bowl and the joint. It catches ash and debris before they enter your bong, keeping it cleaner for longer. If you use your bong frequently, an ash catcher is one of the most worthwhile upgrades you can make.
