Making oil paint using charcoal

For my Christmas present Tom kindly experimented with trying to make oil paint using an ironstone nodule, with a degree of success. We then played around today using charcoal from the fire and refined the methods to successfully make our own oil paint....now to diversify the colour range!

The piece of wood from last night's fire and using the pestle and mortar to pond it to a fine powder.

Grinding a piece of spare glass with sandpaper before placing the powder and adding cold pressed linseed oil - the mixture was then well and truly mixed and ground by using a muller - or in this case a flat-bottomed glass.

The oil paint was then put into tubes for later use. 

Using the charcoal paint - I added it to a little cold wax medium to make a less concentrated paint. 

For Christmas Tom had given me a small sample of ironstone paint which I also added to a small amount of cold wax medium....and below.
