carragheen moss
A dark purple, branching cartilaginous seaweed
(Chondrus crispus), found on the coasts of
Northern Europe and North America. The moss is
used in the preparation of MARBLING SIZE , about
4 ounces of the moss being sufficient to make 9 or
10 quarts of size. Carragheen moss was first used
in making marbling size sometime after the middle
of the 19th century. The extract of the moss is
also used as a thickening agent and viscosity
stabilizer in some adhesives. (217 , 237 , 335 )
