try adding "Modeling paste"- is that what I'm thinking?? i remember
white paste. You could try the flour but it will mold if unused and
I can't promise anything after it's used. I know whatever you add-
flour or other foreign "Live" substance will mold in the jars if
reclosed and left to sit. They will smell really bad. So whatever
you use to thicken, do it right before using. Check out "the
Artist's Materials and technique handbook". You could make an
impasto and add different gels and substances to experiment with.
Sounds like a great exploratory lesson.
