These have been in my studio for a little while and I haven't cut them open yet, but I have used them before in tubes. Too busy using up my stock of oil-based inks and messing around with gelatine-plate printing which uses acrylic paints. But these are gorgeous inks, made in Wales by Cranfield Inks, a family run business. The Managing Director, Michael Craine sent me a very detailed and informative email which absolutely confirmed to me that I was getting the right inks for the studio. And I have the DVD of artists using them which you can borrow and watch, too.
The colours are dense, intense and translucent which means you can layer them up.
Here is the full list of both etching and relief inks:
Caligo Safe Wash Etching Inks
Caligo Safe Wash Relief Inks
Process Blue (Cyan)
And you can wash them with water and soap which makes cleaning up absolutely painless. And the rags/scrim can be washed and used again rather than putting them in the bin.
Me, I'm itching to use the Napthol Red. What about you?
