marbling combs
Instruments, generally with wire teeth, used for
combing marbling colors while on the surface of
the size. They are usually of two basic types:
those with relatively short teeth, used for
combing on the surface of the size (and sometimes
called "top combs" because the teeth are allowed
to touch the floating colors); and those with
relatively long teeth, which touch the bottom of
the trough while the comb is being drawn (and
sometimes called "bottom combs"). In the
production of comb patterns, four combs with
variously spaced teeth are used; the most common
are: four teeth to the inch, two to the inch, and
double combs. in which the spacing of the teeth is
alternately wide and narrow. (335 , 369 )
