closing the grain
Originally (not long ago) I figured that closing the
grain was the equivalent of smoothing the surface with
finer and finer abrasive. The other day I came across
the idea in jadework where abrasion rips up tiny bits of
crystal below the surface - undercuts I believe they
call it. Now I am beginning to realize that smoothing
has to be done so that it doesn't create damage below
the surface. I suspect that is why diamond pads seem to
work so much better that silicon carbide sandpaper - the
diamonds seem to cut crystals rather than dislodging
them. Just a theory. However, considering the vast time
one can spend polishing, the more you understand the
quicker it will go. Any stone nerds have an opinion?
Late night with a Seattle blues station.

Bill
