Chalk

by wickinc

Making chalk:

2:1 Plaster of Paris : Water

You can add food colouring to change the colour of the chalk.

Pour it into a mold and wait for it to dry.

Experimentation is needed to see how long the chalk will take to dry. Also to find out which type of mold works best, if it needs to be lined ect. How thin can we make the mold and how brittle the chalk will be.
