My father is on the board of a small historical society which wants to start a
"hall of fame."  The plaques will be outside, though protected somewhat from
the weather by a glass barrier.  I have a vague memory of a process of using
porcelain, firing the words and images onto the surface.  They are sometimes
used in exterior exhibits.  Does anyone know of a company that does this work?

Thanks,
