Re: Resinotype: Melting rosin + pigment mixture -> question
Loris, Please allow the interjection. I now have a lump of Lamp Black + Rosin + Alcohol mixed, believe it or not, at about the same time as you suggested using Alcohol, yesterday. It reminds me of when I tried Bromoil some years ago. That Bromoil ink, which I still have, still resembles chewing gum in texture and I really do not know what to do with it. All suggestions OFF LIST, please.

A question comes to my mind (after reading about rosin/colophony in wikipedia): Do we need strictly heat the rosin + pigment mixture for grinding? Wikipedia article says rosin is soluble in alcohol; can't we just dissolve the rosin in alcohol, add the pigment, grind and then wait for the - irrelevant - alcohol evaporates?
