Zong Cone Bowl — ZongGlass Borosilicate.

The Zong Cone Bowl is a hand-blown borosilicate glass bowl from ZongGlass, made at the Phoenix, Arizona workshop by the same team producing Zong bongs since 1992. Made to order from durable borosilicate glass with a 14mm glass-on-glass joint for a sealed, airtight fit with ZongGlass bongs and compatible setups.

Borosilicate Construction

ZongGlass bowls are made from the same borosilicate glass used across the ZongGlass lineup. Heat-resistant and chemically inert, borosilicate handles the direct flame contact of every session without accumulating stress damage the way soft glass does. The result is a bowl that performs consistently through long-term daily use.

Glass-on-Glass 14mm Joint

The Zong Cone Bowl uses a standard 14mm glass-on-glass joint for a secure, airtight fit. The ground glass seal keeps the vapour path clean and eliminates the airtight failures common with grommet-based connections.

Made by the Original Zong Team Since 1992.

Every Zong Cone Bowl is made to order at the ZongGlass workshop in Phoenix, Arizona. Standard lead time 2–3 weeks; up to 30 days at peak.
