Paper marbling; the art of floating ink on a liquid in order to create patterns which are then printed.
I used to make Turkish marbled paper like those on old endpapers. Highly coloured and often combed, they answered to names such as non-pareil and peacock. The process was controllable so many similar sheets of paper could be produced.
Nowadays I marble paper the Japanese way to produce suminagashi; non-repeatable, simple and elegant designs on paper.
I teach others how to float ink on water too.
My pieces are held in collections including the following;
The Olga Hirsch Collection, The British Library
The Rosamund B. Loring Collection, Houghton Library, Harvard
The Schmoller Collection, MMU, Manchester.
