Jesmonite
Jesmonite uses a 2.5 part dry material to 1 part wet materials.
It needs to be sired genitally but thoroughly so that you don't need introduce air but fully mix the materials.
I chose to use the pigments for the Jesmonite, in my case you can add up to 2% of the volume
I used a mould that came as a sample for a coaster and our egg roto-cast.
