What dies would be used to die stone like the geodes done in Brazil,
and what would the chemical be that carries the die. Lloyd,

This can be a very complicated answer to a very complicated
question. If you are planning to do dyeing at the commercial level,
there are many proprietary procedures used by various companies. I
understand there are a number of books available that provide
on the subject but will have to depend on others in this
regard. You might do a search of the Lapidary Journal
archives…John Sinkankas wrote a number of articles for LJ in 1963
and the book The Agates of North America contains some useful

If, however, you are planning on doing a bit of dyeing on a small
scale, look for a great little book “Gemstone and Chemicals” aka “How
to create color and Inclusions” by the late George W. Fischer, Ph.D
dated 1991. Mr. Fischer was a chemist who spent about 25 years
researching how to color agates and jaspers using inorganic
substances. I have used many of his formulations and found they
really work! The problem you face is that there are a very limited
number of these books available.
