- My three friends and I (we call ourselves the Marble-ous Four) were
attempting to marble with acrylics for the first time this past
weekend. We did not have very good results. I have been folowing the
string on aluming and the newsprint, but I am also wondering if the age
of the size might effect the marbling results. Our powdered carragheean
(purchased from Colophon) is approximately 5-6 years old. It has been
kept in my house and not in the garage where the temperature may effect
it. What is the shelf life of this product and what would the effect be
if it does become too old? Thanks for any advice you can give me.

- I have successfully used carragheean that is at least 5 years old, maybe
even 8, purchased from Colophon and have never had a problem with it. A
trick I learned from Peggy Skycraft was to make it thicker than you need and
then thin it down with water when you are ready to marble to get just the
right consistency. If you make it too thin to begin with, then you can't
correct it. One problem may not be the carragheean but the pH balance of
your tap water. When all else fails, you could try distilled water, rather
than tap water, to see if your marbling size is better behaved. There are
just so many variables as to what makes marbling work and what doesn't.
Experiment and keep good notes!
