If you want to cast a solid colour, mix the pigment into the pre-weighed AC100 liquids, blend thoroughly and slowly add the Jesmonite base to the liquids whilst mixing until the mix is smooth, flowing and free from lumps. Alternatively, you can add the pigment to the mixed Jesmonite, experiment by swirling it through to create different effects. You will not need much pigment; the standard addition rate is 2% by weight of total mixed Jesmonite (or 20g/kg) so for these sized casts you will only need a few grams. If you add too much pigment, it will stop the Jesmonite from setting or make the cast object weak and breakable.

​

For simple casts like the enclosed, pour a small amount of the mix into the mould and coat the surface evenly. To avoid any air bubbles on the surface, use a small clean, dry brush to coat the surface evenly and get into the edges of your mould. You can tap the mould too to get rid of surface air bubbles. Then fill up the mould with the remaining mixed Jesmonite, gentle tapping of the mould will help any air bubbles rise to the top surface. Then leave your cast for about 30-40 mins to set. Once you have taken it out of the mould, it will gain its full strength after 24 hours. Jesmonite needs all the moisture to evaporate to gain its strength, if you leave it in the mould it will sweat, may mark, and not dry thoroughly
