I just asked a friend who worked for them for some years, and he said
that they actually used boiled carragheen moss for size, but they did
use oil colors and oil-based printing inks.
Natural Carragheen moss contains three distinct types of gels,
designated by a different Greek letter; Kappa, Iota, and Lambda.
Kappa and Iota are less soluble and tend to form very viscous, even
solid gels. The powdered carragheenan extract that is generally sold
for marbling here in the US is refined lambda, which is a very fine
gel that never really solidifies.

they wereusing? Much as MC HPMC and HMC have various kinds and grades,
so does CMC. There is a kind made that is so viscous, it is used as a
buildingmaterial and in architectural restoration. While I've never
used it for any method of marbling, I do know paperconservators who
use certain types of Sodium CMC in very low solutionsas as an
have the impression that it is a lot more viscous and also also
morepolar, which may limit the paint that is used to oil. In fact,
Ithink that Asco marbling, a kind of oil-color method developed
byartists at the Ascona School in Switzerland, is made on such a
viscoussizing. If you try it out, let us know how it goes! Jake
