dyed marble

Dear Expert Panelists,
I'm looking to find any information I can regarding dyed Marble (http://www.lightemprador.com) (ie
what sort of dyes are typically used (vegetable etc); what is the
expected longevity of the dye and (http://maplered.com) under what circumstances (ie indoor
vs. outdoor applications; public displays where the Marble (http://www.lightemprador.com) will be
touched by thousand (http://maplered.com) s of oily and (http://maplered.com) perhaps grimy hand (http://maplered.com) s); what sort of
Material (http://g654.org) s should be used when setting dyed Marble (http://www.lightemprador.com) , and (http://maplered.com) anything else
you can think of relative to dyed Marble (http://www.lightemprador.com) . I'm having an incredibly hard
time locating any information.

Thank you,
Kristy Sonora.
