I have been marbling for nearly twenty years (no hobby-full time
profession)...in all types of climates and temps! If your alum solution is
correct, there is no need for SALT! When the temp. is higher than usual, I add
more carrageenan powder to the formula when mixing the batch. I always use
steam distilled water to make the sizing and alum solution...when the size
begins to water down after much use...then it's time for fun and
experimentation. There really is a LIFE beyond pretty patterns! Most of my
best work has come from bad, nasty size...several weeks old! That's when the
Creativity Muse takes over. Sometime consider the technique of marbling as a
"tool" rather than a set of rules and regulations to follow. Life is too short
to worry about every variable in marbling. Think about the 17th century
marblers...they made due with what they had and most probably stumbled across
some lovely new ways to marble!!! -Milena
