Experimenting with the larger ‘droplet’ by trying resin pigments. Having been told that the colour bleeds into the clear cast resin during curing, but wanting the swirling effect of marbles, I tentatively used the the special resin pigments, but also tried using water based ink to see what would happen.
The inks didn’t work (kind of expected). To my surprise the resin pigment worked brilliantly and just as I’d wanted it to. I’d mixed the pigment with a small amount of resin prior to putting it in the casting and can only assume the advice previously given was as a result of the person stirring the neat pigment directly into the casting. If I’d known that I’d not have attempted to use water based inks.
Still, great fun experimenting.
Unfortunately I think I may have over done the catalyst as the cast has a crack in it. It did start to cure far too quickly in my opinion and did become rather hot. Much more so than the previous, but granted smaller, resin cast I had produced. It may have also been a reaction to the water based inks injected into the resin as well.
The inks provided me with an interesting chemical reaction and a slightly humourous one at that!
Nevertheless, a valuable learning curve.
