More time with the Splashart machine today.
Had a go with the food colouring in the bottom glass container. To be honest I'm not happy with the result.....
...... things seem to work better with the colouring in the reservoir, which I don't like doing. I had a blocked valve last week after adding a red colour. I t seems after a while the pigments in the colour began to solidify for some reason. It took ages to clear the blockage.
