Different minerals will behave differently, so I doubt there is a "one size fits all" type answer.

I suppose in some cases there will be no answer at all.

Not that I will be able to help you more even after knowing details.

However rasool083:, that doesn't mean you shouldn't try to be clearer.  Just to be polite to us and our time, really.  You apparently want to dye stone, instead of paint it.  I suppose that depends more on how porous the stone is, than the paint and solvent.

thanks all,
excuse me for my poor English,
I need to dye the stone (marble or travertine ) that contain CaCO3,
perhaps I must searching about solvent and color with very small molecules size.
Dear billnotgatez thanks for the key words,I will try to google them.

You're likely looking for a dye molecule that is slightly acidic, to really bind to the calcite crystals.  But will it change color when neutralized?  I've said something similar recently -- people have been dying marble since the time of the Ancient Greeks -- all those classical white marble statues were garishly painted.  So this technology should be well known in the business, ask some old timers if they have insights.

Marble was used for printing.

"Lithography" and "marble printing" give search results.

hello,
I studied about stone dyeing. it apply for gemstone http://rocktumbler.com/blog/dyed-gemstones/
I found out that I need a solvent that penetrating into the stone easily and it can carry the pigment or color into it then the solvent will evaporate and the color remain there.
accidently, I test a herbicide (trifluralin) and it was stain the stone deeply and I found out it`s solvent do that and it was Xylene. but not yet perfect .
in the tile industry they using a color for making texture and then penetrating it with " Metasorb " into the tile I dont know the mechanism of it. perhaps it`s wet-ability is very high

which solvents do you suggest me for next my tests ??
