Trouble-shooting:

—The first dropping of paint is a test.  If a color sinks to the bottom, add more oxgall.  Dark colors need more oxgall than lighter colors. White gouache has much oxgall in it already.

—Oxgall is bile, from the beef industry.  Oxgall enables the paint molecules to bond.

—If a color has too much oxgall, use only the tip of the stylus to drop the paint onto the caragheenan size.

—Always rinse the freshly marbled paper.

—Clean off the size after each paper.  I clean several times.  The surface of the size gets dry and will crack if not cleaned thoroughly each time.  The paints willl crack if the surface is not clean.

—Designer watercolors have too many additives. They will sink to the bottom.

—You should be able to over-marble your first design after it dries, without applying alum again.
