Adult supervision always needed with these projects! 🙂

Quick video using alginate to make a mold for a hand cast and an object. I had to use some out of date alginate, just to use it up and thought I would experiment with casting a hand holding an object which was/is a small ball based on a drawing I did a while back.
The video is a bit rough and ready and shows what not to do in parts, for example, pour your alginate powder into water, rather than pour the water into the alginate powder. Find yourself suitable containers to house the alginate in accordance to your project.
Try to release as much air as you can by tapping the mold after pouring the plaster of Paris into the alginate. Go careful when cutting the alginate away from your lifecast to avoid damaging your plaster of Paris cast.
The alginate used in this video is a 3/1 mix, which means 3 parts water to 1 part alginate. The plaster of Paris was mixed to a 50/50 mix, which means 1 part plaster of Paris to 1 part water or 50% water to 50% plaster of Paris.

This video shows how to make a hand lifecast bookend model or prototype to use for a latex mold for casting further casts from concrete. The hand is made with using alginate and you can see how to make a hand lifecast in this video on the Dramamask Evolution channel – video link: https://youtu.be/g5HmOXGA82E
The hand lifecast, casted from plaster of paris, is embedded into a plaster of Paris panel or slab and the book end model is created using the techniques in this video.
The model cast is created to make the shape ready for latex molding and subsequent casts from the latex mold. When the mold is created, future casts will be casted using concrete for a substantial bookend which will be ready for practical use. A video showing the molding and casting process for the book end will be shown in a future video. In this video, the model is made and a painting effect shown ready for the molding process.
