Hi
glass beads and some sands can be died using the ink from pens designed to write on (window) glass

Subject: Re: Where to purchase sand for analog modeling - USA
Dear all,
I am a research assistant at METU, Turkey. I am trying to prepare
sandbox model for classes. It will be expensive if I order sands from
the mentioned web site. I have collected quartz rich clean beach
sand. What i am planning is first sieve and dye them to have different
sized and colored sands so that I can physically separate them after
using. Does anyone tried dying the sands? I am not sure about the type
of dye I should use.
I considered the physical effects of the grain size difference and dye
on the model as minimal.
If you have further suggestions, they will be greatly appreciated.
Regards,
Mustafa
