The Stardent Ivory Super Hard Stone is an extremely hard synthetic Super Hard Stone type 4. This Stone is often used for stumps, dental arches and control models for crown and bridge technology as well as frames. Due to the variable mixing ratio of this gypsum you can control the fluidity according to your needs. The manufactured models will be less likely to splinter and break during sawing and scoring. An extremely low expansion is another characteristic of this gypsum, only 0.08% after 24 hours. Due to the variable mixing ratio, between 18-20 ml water is 100 grams of powder. This will give you a processing time of 8-10 minutes and a binding time of about 17 minutes. Schouten Dental supplies this gypsum in the color ivory in packages of 4.5 kg, 10 kg and 20 kg.
