The Eyce Quartz Straw is made from a fused silica noncrystalline (glass) form of silicon dioxide (quartz, sand), creating a highly cross-linked three-dimensional structure. Eyce’s Quartz Straw can be exposed to high temperatures while maintaining optimal concentrate flavor. The perfect upgrade for the Eyce Collector or accessory to convert the Eyce Shorty into a Straw for easy concentrate consumption.
