Subject: LapDigest News for Issue No 256 - 12/30/1999

The Digest received Christmas greetings sent to all of you

And for those of you going to Quartzsite, they have a web
page at which lists all
scheduled events.

OK The New Year is coming. Please take care during the
Celebrations; appoint a designated driver. Better still,
appoint a designated drinker. Be careful. There are a whole
lot of fools out there!!

The new year is the time to reexamine your life and resolve
to make changes in the coming year. Most of us make vanity
resolutions (e.g.; loose weight, etc.) when we should be
making lifestyle resolutions. I commend to you the ideas in
the letter from Anna Quindlen as bases for your New Year's

I do hope each and every one of you has a great 2000, a
healthy 2000, and a prosperous 2000!

..and a fun 2000!!!


Subject: NEW: Need Help Finding an Address

Hi- just went through my saved back issues of lap
digest and could not find the article on the rock bowl
carving. I remember there was a site recommended to go
with the article and for some reason it no longer is
on my server. So if anybody can remember where the
link or what back issue the rock bowl carving article
was in or even the person who wrote it would get in
touch with me all of the better.

I also do web sites so if anybody wants to trade
material for services hey I would love too work with

The artist's name was Max Krimmel and you can find
him through search engines; the first two URLs I
came across were:
(continued from above)krimmel.html

Neither of these is his own URL, but you can find it
yourself via our new search engine on the website: You will enjoy this and it is not
difficult nor complicated to use! Try it and please tell
me how you liked it! hale

Subject: NEW: Opal Rubs

Last summer, before going to Wildacres, I bought some Opal
rubs from JR Schroeder. Honestly, I had never seen a rub
before, and didn't know what to do with them, but I was
sure our instructor would know, and I would learn something
new. Well, neither he nor anyone in the class he had ever
heard a of an opal rub! So I was on my own.

An opal rub is a stone with opal on one side, looking much
like a seam opal. The opal looks like a paper thin layer of
opal on the stone; it may be on a flat or curvy surface.

The flat surfaced ones obviously may be capped, but what to
do with the wavy ones? I tried flattening one and quickly
ran through the opal layer back onto stone.

Anyone have any experience with rubs? If so, can you answer
a few questions?

.. Exactly what is a 'rub'?
.. How do you work or treat one?
.. On the curved ones, do you ever cover them with a coat
of clear epoxy or other clear resin, or what to do?

It seems that the opal layer is so thin that it needs some
protection of some kind. Is this true?


Subject: NEW: Source of Warm Water for Wet Grinding?

(This question and the first three answers were copied from by agreement of the authors. - hale)

I have a question some readers might be able to help with.
My work shop area for working with rocks does not have
access to a water supply. I just carry water out when I need
it for washing rocks. I have a recirculating pump for my
grinding, sanding, etc., but hate to work in cold water.

What do people use for heating a bucket of water for the

Any help would be appreciated. Thanks beforehand.

I'd be willing to bet that a fish tank heater might work

Joseph George
First, I'm sure you can take a bucket of warm water out with
you to start with. Then - and I have never done this, but
it seems logical!- you know those little coffee heaters that
hang over a cup of cold water and heat it for coffee? One
of those hung over the bucket of warm water would keep it
warm, I'll bet. One problem would be the lowering level of
the water as you start to use it up.... you really need a
'bottom' heater, like an electric iron, turned upside down,
as a platform on which you rest the bucket.

Hope these ideas help!! Water sprays from cabbing in winter
really ARE COLD!!! And the cold becomes painful!


Just a warning (I keep fish) - if you don't keep a fish tank
heater under water it burns out very quickly.

Just a caution - recirculators can pick up grit and chunks
of ground rock and cause scratches. I personally use only
clean water on feed.

Kreigh Tomaszewski
Well now, how warm do you want the water? You can use a
crock pot on the lowest setting. Then have your drippings
go into the pot over and over.
OK, Guys -- do you have any suggestions to add to these?


Subject: NEW: Digging Sites in the Southern States

Will be driving from San Diego, California to Florida soon
and thought members might be able to advise me on rock
related places not to miss en route. Have not been able to
get any books showing digging sites in the states east of
Texas. Any ideas??

Subject: Re: Does Fluorite Fade in Bright Light?

Mary Sharp:

In regards to your fluorite, I am not really that sure
about the sun's exposure on your specimens. I do know
that sunlight will effect amethyst if left in direct
sunlight. And I do know that too much heat generated
while cutting fluorite will take away some color.

Subject: BIO: Dirk Holland


My name is Dirk, and I am 39 y.o. I tumbled my first stones
when I was 8, and first cabbed and mounted a piece of
malachite when I was 17. I've been a rockhound since the
first day I picked up and placed that shiny pebble in my
pocket as a 6 y.o.

Today, I am a US Army helicopter pilot (stationed at Ft.
Hood, TX,) and still manage to grab a few rocks from all of
the places around the world I visit.

I use a Graves 6+1 6" polishing wheel and saw combination to
work my material at home.

I have 3 boys, 9, 5, and 3, to whom I hope to pass on my
cabbing knowledge, experiences and equipment when they are

As I hinted to earlier, I tend to seek out and find most of
my material, and only purchase that which is locally
unobtainable. Having grown up in south eastern Arizona, I am
well versed with the back roads and materials found in AZ,
and therefor have a large(for me) collection of material
(not for sale, sorry).

Not one to brag, but my present cabbing material consists
of turquoise and malachite, Mexican fire agate, hematite,
amethyst, various jaspers and agates, mahogany and snowflake
obsidians, tigereye, peridot, garnet, quartz, various
geodes, lapis lazuli, coral, petrified wood, and of course
numerous fossils and crystal specimens of various minerals.

I also have some material that I have yet to identify, more
on this in another post.
