Hello, just a quick one on how to use LIT, the light emitting pigment. IMPORTANT only mix up as much as you need. LIT will not store even in an airtight container. Once it mixes with SuperBase the chemical reaction means it will start to go hard. My fave ratio is: 5 parts LIT 2 Parts water 2 Parts Superbase But - you could halve all of those if you want to mix up less :) But feel free to experiment. PS - you can also mix it straight into linseed oil to make and oil paint. If you would like to try out LIT and don't have any, you can get it (along with SuperBase) from http://CultureHustle.com/ Have fun! See you soon, Stuart x
