Hi, I am very new to Resin. I would like to create some glass art. I wish to take a sheet of 5mm glass (say 30″ x 40″) and use various colours of resin to make a random design. I want to have 3- 4 colours and pour them separately on to the glass in random places then using a hairdryer mix the colours. Please can someone tell me the most suitbale resin (and i presume hardener) i would need for this and is it just as simple as adding the colours (is it powder) to the clear resins? kind regards Jamie
