Subject: LapDigest Issue No. 131 - Saturday 4/4/98

I noticed the other day that Alan Silverstein had subscribed
and I welcome him. Alan produced the big file on tumbling
(Tumbling.txt) which is in the Archives, and graciously let
us have a copy. He has now 'updated' the file with more
interesting tumbling information.

We have several papers about sphere making, and I am trying
to put together a whole issue on this one topic. My birthday
wish was answered and we received a complete paper on how the
author makes spheres. If you have anything you can contribute,
please write it up and send it in! Or write me and we can
discuss what you want to write up.

Have a great weekend! Stay safe but above all, have fun!!!

Subject: NEW: Tumbling question

I have been asked if there are any instructions for tumbling
the various types of material by it hardness, i.e., type of
grit to type of harness and time tumbled.

In referring back to the tips and hints received I didn't see
anything on this subject. Anyone with suggestions? A chart
of some type for cross reference would be helpful if there is
such a thing.

Subject: NEW: Red Tigereye?

Recently, over on the Rocks & Fossils mail list, someone
wrote in that they had seen a bead strand of nuggets, and was
told it was red tigereye. Then the question was whether it
was real or dyed. Several people responded.

One person said brown tiger eye, when heated for a while,
turns about a brick-red color. Another said that red does
occur in nature, but most of what you see is ordinary brown
tigereye after it has been baked for about an hour at 400 deg.

Can any of you add anything to this?

Subject: RE: Coloring Agate Slices--Historical German Method


Greetings Hale:

Can't resist saying "Bravo" to the oration on coloring Agate.
It was exciting to see the beginnings of the process I've
enjoyed for the last several years. Even though the
advancements in chemistry have shown us alternative methods,
the classics never die.

Today, thanks again to those who came before, and shared the
knowledge, we can create color as found in nature, and also
it's most prized inclusions. Not only grow moss and dendritic
inclusions, but to an extent control their growth to provide
discernable figures, right into the stone itself.

Todays inclusions are currently limited to Copper and Tin.
Tomorrows are on the drawing board. Red stone with silver
inclusion, Hale?

We live in a world of colors!
