Carborundum

Carborundum
Using carborundum powder to add areas of tone, texture or very strong colour is exciting.  The powder comes in three grades; fine, medium and coarse.  By mixing the grit with PVA wood glue a surface is created which holds a lot of ink. 

Use it by painting the surface of your plate with wood glue and sprinkling the grit on like pepper and shaking off the surplus.  Or make a mix in a jar of wood glue, grit and a little dark acrylic paint so that you can see the mix more easily when painting it on to metal.  Even if used very sparingly you will be surprised at the amount of ink that is held.

I like to use lots of carborundum and glue mix painted directly on to a thoroughly degreased aluminium plate so that I can achieve strong blocks of inked areas.  I then register this with another plate of aluminium with perhaps a combination of more carborundum and some drypoint drawing.
