Martin’s demonstration was more colourful than most and anyone coming along unequipped with a large cardboard box might have become quite colourful themselves by the end of the session. Martin started with four pieces of turned wood and coated them all in a base layer of paint. For the marbled piece he used a pale base and for the others a black one. For the marbling paint was dripped into a large plastic bucket containing a small amount of water and the pale surface of the piece then dipped into the water to get the marbled effect, (the colour dispersing in the water providing the randomness of the effect). The spun colours were created by applying a moderate amount of the colours to the centre of the platter and then turning the machine on at about 2,500 rpm. Note the labelled pallet since the colours are apparently all magnolia to start with.
