Subject: LapDigest News for Issue No. 39 Fri Sat 8/1/97
I have no new lapidary items to post today, as none were sent in. So
it is RECYCLE time again. I went back into the Archives, and looked at
the old queries which did not get answered, and am reposting them once
The thing is this: no queries from you, no answers from you means no Digest
to you. A Digest can only be sent when there are some messages to send.
Bill Cordua, Professor of Geology at the University of Wisconsin - Riverview
has written a paper for the Digest on hardness of lapidary materials -
how to define hardness and measure it, and what it means. This paper is
of such length that it will be published as a whole issue. Please send
in - starting now - any questions you have about hardness, specific gravity
or any of the other measures which characterize the materials we use.
We will try to put together a couple of issues just on material characteristics.
One member of the list has a housekeeping problem for which we have tried
to find a solution. When he prints out a Digest, he gets partial sentences
and cut-off sentences. He has tried saving the Digest to a file and printing
the file, but the same problem recurs. DOES ANYONE ELSE HAVE THIS PROBLEM?
Another member said that the text runs off the screen and she has to
scroll to see the ends of each line.
We have checked our software with the software developer. The software
does not do anything with messages except take them in and sends them
out. It does not reformat messages. The format of a message depends on
the format given the message by the sender's software, except for the
Digest News section, which I write. I try to give all sentences in that
section hard returns.
IF ANY OF YOU HAVE A SIMILAR PROBLEM, PLEASE WRITE DESCRIBING THE PROBLEM,
THE OF TYPE MACHINE YOU HAVE AND THE SOFTWARE YOU USE TO RECEIVE MAIL
AND TO PRINT OUT MAIL FILES. THANKS.
And a note to everyone in the midwest. There will be a gala celebration
honoring Betty Scheffler, and celebrating the Scheffler Geode mine (it
is being closed to make room for a highway) on September 20th at the mine
at Alexandria, MO. (For those not familiar with this mine, it is almost
at the junction of Iowa, Missouri and Illinois.) Anyone desiring full
information may send me an e-mail letter and I will send you the full

Subject: RENEW: Vibrating Lap Grit (was 27-2)
Does anyone have a secret for making the slurry thicker for a vibratory
lap? My 80 grit and 220 grit stay fine in the pan. The 400 and 600 grit
are both light and want to vibrate out of the pan. Any ideas?
Subject: RENEW: Orienting Cat's Eye Aquamarine (was 31-2)
I picked up some cat's eye aquamarine a while back but I'm having some
trouble orienting the stones. I've got a polariscope but that's only
giving the center axis. How can you tell which direction the grains run
on transparent rough? I would appreciate any insights.
Subject: RENEW: Carving Mexican Opal (was 24-4)
<<In her post on the change in opal colors, in Issue #23, Carol
Bova asked, almost as a by-the-way question: "In the meantime, does
anyone haqve any advice to give on free form carving of Mexican opal?">>
Subject: RENEW: Polishing A Star Ruby (was 23-3)
I'd like to know what is used for a final polish on a star ruby.
Also thanks for the help on the opals.
Subject: RENEW: Cutting/Orienting Rainbow Obsidian (Was 20-2)
I have a large chunk of Rainbow Obsidian rough. I have been told that
there is a special technique to cutting Rainbow Obsidian to produce a
heart shaped rainbow instead of a a circular rainbow. It was explained
to me once but I have forgotten the directions. Can anyone help with this.

Subject: RENEW: Tiger-Eye Treatment (was 13-1)
I've seen nice catseyes produced from tiger-eye. I understand they use
acid to lighten the tigereye to the light honey color. Oxalic acid might
be the acid. Is someone familiar with the exact process?
Subject: RENEW: Polishing Intarsia (was 3-3)
Is there an easy way to polish intarsia made out of material with
wildly different hardnesses ? I made one with a center of ruby,
surrounded by opal, a border of azurite and the remainder of the
stone is agate. It cuts fine, but polishing haa ! Between the
undercutting and the small scratches on the opal my piece kept
getting thinner and thinner. I am going to a class in 2 weeks on
Intarsia but I am not real sure I'd want to show this one to him.
I'm sure I'd be Example of what not to do # 1.

Subject: BIO Albert Alberth
I am a Sapphire miner from the Central Queensland Gemfields of Australia.
Apart from my faceting interest, I am concentrating at the moment on the
cabbing of our local black star sapphires as well as the carving of our
lower grades material. I have been mining and heat treating sapphires
commercially for the last 25 years and gemcutting for over 15years. Only
recently have I been dealing and trading sapphires.
I am looking forward to reading + participating to this list.
