Slowing down the drying time of glazes in acrylic
A question from the email bag - Mario asks: I'm interested in glazing, and I've been experimenting with this technique. But I'm running into some problems. I remember that at the workshop you mentioned that if we have any questions, we could e-mail you. For that reason, I'm taking the liberty of coming to you for help. Perhaps you will have the answers to my questions, but if not, maybe you can recommend a website with information or forward my questions to someone that might be able to help.
I'm using GOLDEN paint and acrylic glazing liquid. I'm painting on Arches, 140 lb. hot press paper. I start the art piece by applying an under painting of Van Dyke Brown. After I place one color over another to create a third; for example, blue over yellow to obtain green. Sometimes when applying the under painting and when applying the second color (blue) over the first (yellow) I'm getting hard edges, which are not allowing me to create smooth transitions. How can I reduce the risk of hard edges? Do you think the hot weather of Sacramento is making the paint dry too quickly? Can I use a retarder with the glazing liquid to extend the fluidity of the paint?"
Thanks for your question Mario.
