I worked on a chalkboard some years ago.  I found that the chalk
itself did not really require consolidation as it seemed quite
stable (I think it was around 50 years old) and would be displayed
in a cabinet.  The black paint on the board itself was locally
consolidated where necessary with 5% Plextol.
