Borosilicate is the standard scientific glass used in nearly every piece in the All Glass collection — it withstands thermal shock, holds clean flavor, and is the material used by AFM Glass, Illadelph, HVY Glass, Cookies SF, and every named heady artist carried at Angies Boutique. Soft glass (soda-lime) is cheaper and used in some import pieces; it cracks more easily under heat changes and is generally not the right material for dab rigs or any piece that contacts heated banger or downstem temperatures. Silicone pipes, like the Eyce Hammer and the Eyce silicone chillums in the /collections/silicone-bongs and related collections, are drop-proof and dishwasher-safe but trade some flavor clarity for indestructibility. For function and flavor on a daily-use piece, borosilicate is the right pick. For durability around drops, travel, or shared rough use, silicone is the smart secondary piece. The All Glass collection at Angies Boutique is overwhelmingly borosilicate; silicone alternatives sit in their own dedicated collections accessible from the main navigation.
