Zirconia exhibits the same scratch resistance as Alumina ceramics, but Zirconia will not shatter if dropped. The zirconia itself is colored so the color will not rub off. They are trusted by many dentists to create false teeth. So this means that it is hypoallergenic and safe and will not leach toxins over time. Zirconia is stronger than metal or alumina ceramic so we can increase the threading on our cartridges to ensure a tighter seal. Zirconia as a material also has a very low thermal conductivity so people using them to smoke will not be burnt.
