Open Day on site – so I used the need to stay in the Art Hut, to be available for visitors, as an opportunity to play with my collection of stones – now trying a Neolithic version of oil paint by mixing crushed stone with beef dripping. This is based on pure speculation that the ready access to cattle fat and silt stone might have been combined.
These ‘oil paint’ samples (bottom row) make a deeper colour than the dry chalk (top row) or when mixed with water (middle row). It will be interesting to see how the ‘oil’ colours dry, and whether beef dripping oxidises like linseed oil.
However the most vivid colour comes from a good ‘chalk’ colour directly on to stone. NB – must consult The Rock Lady about this.
