Subject: WELCOME to the New Test Group


I want to tell the new testers some of the things the rest of us already

.....first, the test period will extend through Friday June 20. Then I will
be away in the Blue Ridge Mountains at a retreat named Wildacres taking a
week-long course in Intarsia. The list will be down during this period.
If everything is operating OK at that time, then we will open the list for
general enrollment on Sunday, June 29th. I will write letters to the three
mailing lists and to informing them about the opening of
the list.

....please submit questions (and answers) now just as if the list is open.

.....please do not rely to a particular message by hitting "Reply To"; it
will just copy the entire Digest back and this is REALLY wasted space!!!!
Cut-and-paste if you need to copy a letter being replied to...

.....Enjoy, and you can contact me at

Subject: BIO Mark Liccini

Hello fellow test subjects.How do we begin?I am Mark Liccini a dealer in
Rough Gemstones and Crystals.I have lived on and off in Brazil and still go
there every month.I am a facetor,carver and cabachon maker.I have 2
Gemological degress.
I am gemstone treater(irradiations and low temp heating.) and a cobber
taught in Idar Oberstein.
So,I wish this list good luck and for the life of me cannot think of a
starting subject.I was sent,perhaps by mistake a list of all the starting
participants.And never have seen a more diversified list.Maybe we should
discuss what is going to happen to so many new lists.I am considering to
subscribe to digest versions of all because I am now getting so much mail I
am missing orders!.but in the digest it is more difficult to respond to an
individual post and to file a good technical response for the future.

Subject: NEW dumb question

Hi all,

I love rocks, but still don't know near enough about them. I'm curious about
rodocrosite. I've seen this in small logs, sometimes kinda grown together,
like trees grow. Is this a type of petrified wood? It even has concentric
circles like a tree would.

If not, why does it develop like that? I love small slabs with rind around
the edges, and it would help if I knew exactly what might make these cuts.
Thanks for keeping your snickering to yourself. <G>

Subject: NEW: Surface Treatment of Lapidary Objects

In jewelry, surface treatment is a big topic. But I have hardly ever heard
of it in Lapidary. I started wondering about this about 4 months ago and
have done some experimentation since then. There are at least two methods
of treating the surface: mechanical and chemical.

I bought a small 'sand blast' pencil and have been experimenting with
different ways to use this to texture a polished surface, mostly using
plastic masks to create the design. Then I found that the glass craftsmen
- the ones who make the beautiful sculptured glass for doors, also use a
glass etching paste made partially from fluoric(?) acid to etch the glass
surface, so I bought some of that etchant to try on silica materials (and
a lot of our materials are high in silica)

I would like to hear from anyone who is or has been using either chemical
or mechanical methods to treat the surfaces, and swap experiences.

Hello fellow Lapidaries,

First I want to thank Hale for starting this digest. Good luck with it Hale.

Now on to business.

Although I've been faceting for four years, I've had on several occassions
borrowed a cabber and my daughter and I have cut a few cabochons (mostly
quartz) and enjoyed it. After some further instruction, my daughter
demonstrated cabbing at some local club shows, has cut rainbow obsidian,
agates, amethyst, and opal and is much better at it than I am. I am now
saving money for a cabber and hopefully it won't take the year to buy like
my facetor did. If there are any suggestions about cabbers in general I
would greatly appreciate them. I would like to one day cab some opals
(hopefully as well as my daughter does). :)
