i’ve decided to do my first attempt at coloured lams, i’m at the moment considering (and for the sake of argument) a dark grey/black opaque lam and a smoky transparent grey lam. i’ve been through the archives and think i’ve got my head around it except for one thing. can i buy a white opaque pigment and use that as a base for all my opaque colours and then colour that with coloured transparent tints? e.g. can i make my board the way i described only using a white opaque and a black transparent pigment?
any replies would be appreciated. i enjoy experimenting but i still have to buy the stuff.
cheers for the use of the site, its pretty damn cool
Generally as a rule of thumb the more pigment you add the more opaque it gets.
Test on a piece of scrap foam and use a pencil to write all over it. Cut many 2" square scraps of the SAME cloth that you will be using to lam with. Next get about a dozen small platic cups and pour a little resin into the first cup. Begin adding only a VERY small amount of pigment to it and then lam the test squares over the writing on the blank. This test the transpareny/opaquness of it. Add more pigment to get a richer more opaque color. You can do a few tests per cup becuae of resin/pigment ratio.
Once land a t a decent place, then simply mix the beg batch and mix enough to glass BOTH sides.
