Is a loose gel which liquefies when brushed and stays in place when ¥at rest,? making it useful for developing new techniques. Although it will ¥sit still? on the painting, if you brush back into it you can blend easily because it moves again when you move your brush into it, until such time as it starts to tack up and dry (within a 3 hour session). You can also brush lightly over it wet-on-wet.
