Which Jesmonite product is recommended to make lightweight jewellery?

What is the setting time of AC100 starter kit?
The setting time can be anything between 50 minutes and 2 hours, depending on temperature in the room.
What is the most appropriate Jesmonite sealer for Jesmonite AC100 surfaces?
Jesmonite Acrylic Sealer is the most appropriate sealer for Jesmonite AC100 surfaces. The Jesmonite Acrylic Sealer is a pure acrylic coating. We recommend applying the Jesmonite Acrylic Sealer onto Jesmonite AC100 surface with a dense foam roller rather than low density foam and traditional paint rollers. The low density foam and traditional paint rollers can leave streaks where the Jesmonite Acrylic Sealer builds up unevenly on the ends of the rollers.
Is there a way to use the Thixotropic to allow for vertical modelling?
The Jesmonite Thixotrope is added to the Jesmonite AC100 mix to thicken the material to a ‘gel-coat’ consistency. This is useful when brushing or spraying materials onto moulds with vertical faces as it prevents the material from slumping. Jesmonite Thixotrope is added to the complete Jesmonite AC100 mixture and is mixed in using the Jesmonite High-Shear Mixing Blade. Add drop by drop until the desired consistency is achieved. Typical inclusion rates by weight are 2g–6g per kg (0.2-0.6%) of complete Jesmonite AC100 mix.
Is it possible to use marble powder instead of part 2 of the Jesmonite AC100?
No. The products are sold as a composite and designed specifically to work together. Jesmonite do not test the liquids with other powders.
Can you sand Jesmonite AC100?
Jesmonite AC100 cured surfaces can be sanded using a variety of sandpaper grades to achieve a range of different surface appearances and textures. Most users will start with a coarse sandpaper and then move onto a fine sandpaper grade for finer finishing. The sanding process can be done by hand or with a power sander.
How do I work out how much Jesmonite AC100 material I need?
