colour on marble

Quoted text begins.my question is:
how do I put colour on the stone?
End of quote.

Oscar,

There is a product called "Lithochrome" that is used in the monument
industry to paint stone, bricks etc. It can be gotten in a wide range of
colors, either in spray cans or liquid ,for airbrush application, from a
monument supply company. I know that you could get it from Granite City
supply Co. in Barre Vermont.

This paint is made for use on stone, indoor and out, and as far as I know
its the best you can get. But the salesmen I know, always tell their
customers that in 7 to 10 years the paint will need to be retouched because
some flaking will occur on outdoor stones. If your sculpture is indoors then
it should be good for a very long time. I think that anything applied to
stone will never last forever, so you have to expect that eventually someone
will have to repair the paint.

Painting stone is nothing new, it was commonly done in ancient Egypt, Greece
and others. Of course the sculpture that has survived to the present is free
of paint for the most part, because the paint fell off a long time ago.

Hope this helps.
