- Dec 26, 2004my only problem with acrylics is that I have not been able to get good Stormonts or French Shells. I have mixed the base with watercolor too, same problem. I prefer the watercolors any day, except for the alum need.

That's why acrylics are favoured by many craftsmen and artists. Good acrylics simply can
take a load off your shoulder.
Pure acrylic dispersion is a powerful binder. If a pigment is stubbornly refusing to adhere
to the paper and stay there even if, say, a bookbinder applies glue or paste, i. e.
something containing water, you can trick your pigment into docileness by adding a dollop
of acrylic dispersion.
Several chemists whom I trust have assured me that adding acrylics is okay even as seen
from the archival point of view. Nevertheless I restrict its use to the rare cases when
nothing else helps as I want to stick as near as possible to the materials of old. Besides, it
takes ages to clean the brushes, and as paste is a binder in itself, the need for an
additional binder crops up about once in a year in paste paper-making.
Kremer Germany has a wide range of acrylic dispersions for many purposes. I seem to
remember that the range is smaller at Kremer USA, try their website www.kremer<http://www.kremer/>-
pigmente.com if you're interested. They are very generous in providing additional
information. Dr. Kremer himself is a brilliant chemist, specializing in, of course, paints
