I just got a ceramic lap for Christmas and wanted to know how to
it in. Also how to use it, what stones it's good for, and the Do's
Don't's of using it.
Thanks for any help and may you all have a safe, happy, healthy
prosperous new year.
Hi Ron, I think the post below may answer your questions.

First things first: thank you for writing, sorry
I haven't relpied
sooner, here's to a Happy New Year to you, and please express my
your folks on their exemplary choice of son's names! (And, now that
out of the way...)
You're right, I seem to've lucked out:
I've only rarely encountered the
scratching problems others so frequently complain about with their
laps. Like so many others, I'm completely self-taught in all aspects
lapidary arts. Unlike so many others, however, I don't usually use
extraneous lubricants, when polishing on a ceramic lap, and _especially_
with the Falcon (whose surface is much more finely prepared than
offered by Crystalite).
To replicate my process, you must first
adequately prepare the lap
surface to accommodate the polishing process. Perhaps it's here
that so many
faceters go wrong: as they arrive, straight out of the box, most
laps' surfaces are so exceedingly coarse that they're incapable
even the most basic prepolishes, let alone anything resembling a
polish! To remedy this, begin by grinding a 1/2-boule of Synthetic
-- the cheap stuff - readily available from either Rob Kulakofsky
or Jeanne Ridolfi at <www.rockpeddler.com>,
others -- lengthwise, on a 360 mesh lap. What we're after, here,
is a long,
flat facet, which will be used to first smear our compound onto,
burnish it into the surface of the lap. You will not only be using
this as a
tool to prepare your lap this first time around, but also, to retouch
(and your BATT Lap, too) from time to time, just to maintain it/them.
scrub the surface of your lap with a 3M "Dobi" pad and
some dish detergeant
under hot water, to remove any stray oils which might result in
response from the lap's surface, when applying the diamond compound,
we'll deal with next.
Before we even get there, though, it's
important to come to terms with
what this lap is all about, compositionally, because it's a bit
than most of those you've probably come up against, so far. What
ceramic lap "do it's thing" is its "quasi- microcrystalline"
which comes a result of its makeup: aluminum oxide particles (read
mean "Linde C" powder) in a substrate of a hard type of
perhaps?). To put it another way, you might say that it's very hard,
only where it's very hard... and where it's not, it isn't. (Hmmm...
famous sports legend am I beginning to sound like now?) As a result
what we need to do, before we can polish anything, is to reduce
and begin to
polish the overall surface of the lap, so that whichever size of
compound we choose to use, we'll wind up with _that_ compound's
ending up as the _only_ particles in contact with our pre-polished
As with anything else in this life, if we try to scrimp on our crucial
work, we're sure to pay for it later, in scratches!
Okay, so what I do next is to take the
aforementioned Crystalite spray
diamond (also available from either Rob or Jeanne) in its 50,000
(for surface preparation on the Ceramic lap, or for a final polish,
BATT, as needs dictate), and pump 6-10 spray shots of the stuff
surface of the stationery lap from a distance of about 6-8"
above it. Thin
this out with a spritz or two of isopropyl (rubbing) alcohol, from
separate spray bottle. Next, we stand over the machine and smear
compound around with our "recharge burnisher" (that flat-sided,
boule we'd prepared, earlier), so that there are no dry spots to
burnisher and send it flying, once we're at speed. Now, turn on
to about 1/4 of it's top spindle speed and, with the boule aimed
lap nut towards the outer edge, use BOTH HANDS on the burnishing
slowly move it back and forth, from the center to the edge, pressing
downward with an even ~7-10 lbs of force. Expect to invest about
half to 3/4
of an hour of just standing there, slowly sliding back and forth,
hesitate to spray more of either the diamond or alcohol sprays,
You'll know when you're done two ways: first, the lap will begin
like it's nicely prepolished, but with a faintly pitted surface
occasional, minute AlO2 grains have pulled out); secondly, you'll
that the entire surface of the lap feels, under your burnishing
much like the surface of a smooth Formica countertop would, under
fingertip... almost waxy, but smoother.
Once you've attained this surface, you're
nearly home! All that remains
is to rewash/scrub the surface, as we did at the beginning, then
let the lap
dry in your normal dish drain-rack, then remount it onto your machine.
time, however, what we're going to do is to first turn the dry lap
on, up to
~1/3 of its speed, then use a single burst of the diamond
spray from about
a foot above and, quickly, before its alcohol propellant dries,
surface from center to edge (in one pass) with a doubled-over paper
(As I'd said in 2000, I prefer both the Crystalite 100,000 mesh
the Bounty "select-a-size" towels, since they both leave
less debris behind
than several others I'd tried, and are tearable into smaller strips,
conservation purposes. Generally, I'll fold each sheet lengthwise,
into 4-6 doubled swaths of paper towel, and use each until it begins
apart. These miniature facet-cleaning cloths, with occasional
Windex, as needed, to remove the waxy buildup of compound, have
I've ever needed to produce great finishes, year in and year out.)
My only two "caveats" to you,
Doug, are that you first use a light,
oscillating motion, when polishing on Ceramic, and, second, that
you be sure
to re-inspect each facet you're initially excited about from two
directions, before moving on to the next. On some materials (and
Garnet varieties come to mind, here) what at first looks utterly
can often leave you with a very _different_ impression, a few moments
unless you take that one last look-over. Well, that about does it,
Please keep me posted on your progress, and let me know if you run
things that go bump in the (polishing) night...
All my best,

Subject: Cabbing on a flat lap
Date: Fri, 03 Jan 2003 12:11:50 +0000
To: "LapidaryArtsDigest" <firstname.lastname@example.org>
At Christmas I also did a cab on my faceting machine for the first
time. I bought a foam rubber disk
thing to convert my machine for cabbing, although if you spend the
time you could probably find
something around the house that would do the same thing.
I had a slice of aquamarine which I made into a cabochon pendant
for my sister (too thin for faceting,
slightly included but great colour). Because beryl usually
polishes easily I thought it would be a
good choice for my first cab, and it was. I found that for
shaping and grinding it's far, far quicker
and easier to use the flat laps because they grind much quicker
than a soft surface does. I shaped it
by eye, partly on the lap and partly using a dremel-type handpiece
with some dental burrs (my dad is a
retired dentist). I drilled a pendant hole in it using the
dental burr (much more difficult than it
sounds, even for a thin slice) and buffed the inside of the hole
slightly with a toothpick charged
with diamond grit and grease (polishing the inside of the drill-hole
properly turned out to be too
difficult, but I did manage to get rid of most of the 'frosted'
effect). I polished the stone with a
sort of felt-type lap on the foam disk, stuck down with double-sided
tape (otherwise it flaps around),
with Linde A, water and vaseline grease. This was fairly straightforward
but slower than I expected.
You really need to get the surface >completely< smooth and
rounded before the polishing stage. Some
kind of rubber lap impregnated with pre-polish diamond grit would
probably be ideal - does anyone make
them with the hole pre-drilled in the centre? For some reason,
most of the rubber laps I've seen
don't have a hole! Or am I missing something?
In short, with a bit of experimentation I'm sure any faceter could
learn to cab on their machine. The
only difficult bit was the hole-drilling (I think that you would
probably need to buy a proper
bead-drilling attachment such as the ones that Foredom and Dremel
sell for their handpieces) and the
polishing of the drill-hole. However, I'm pretty sure that
with a bit of patience and maybe the right
size of toothpick it would eventually be possible. My drill-hole
was rather big because a dental burr
isn't really the right size for bead-work. Michael Dyber polishes
the insides of his "luminaires"
(basically long drill-holes right through a large gem), so presumably
there is some trick to it. I
suspect it involves having a small rod that is exactly the right
diameter for the tube.
If you are going to do this regularly, I would recommend that you
consider buying some soft-surfaced
laps that are specially designed for cabbing - but then again, I
think cabbing machines start at less
than a hundred dollars so it would probably be a good idea to look
at them instead.

In an earlier issue I remember someone writing about using a microwave
to heat a stone and change its color. Can anyone tell me if this
safe is it, the stones which can be used, how it is done?

For All National and International Masters, Past-Masters and
This post is simply a reminder that in 2003 the USFG will host its
first National and International Faceting Competition. It
the North American Faceting Challenge -- 'NAFC.'
Since the designs
and rules were first published in the 2001 September Issue of
USFG's Newsletter, and since they have not been published since
some of you, who are most capable - skill-wise, may not
know about the competition, and some of you may have forgotten.
"NAFC" is an OPEN Competition. Please note:
The designs and rules
can be downloaded at <http://www.usfacetersguild.org/events.shtml>.
The closing date is June 20th, 2003; the amount of time between
present date and June 20th, 2003 should be enough for all Master
cutters to cut the two required designs -- Fred Van Sant's "Four
Star," and Charles Covill's "Wind Wheel No. 2."
information is needed, please contact me at <email@example.com>.

Date: Thu, 21 Nov 2002 16:29:21 -0800
From: Dan Clayton <firstname.lastname@example.org>
First USFG faceting list design competition.
Design: Hexagon or Hexagon Cushion in Colorless or Colored
Judging: Highest number for total ISO values at 0, 10, 20,30, 40
and 50 degree tilt with five degree head shadow in GemFramx will
win. Example parameters are given below to achieve this configuration.
Online designs must be submitted by January 10, 2003. Design and
cut entries should have the design posted by that date but stone
will take place at the OPLC Hobnob in Tucson in February 2003.
Publication: All entries will be posted on the USFG faceting list
and possibly on the USFG site as well. Designs may be included in
a USFG list CD. Designers maintain copyright to their designs but
must allow posting on the USFG faceting list site. Posting or publishing
elsewhere is not only permitted but encouraged.
Followup: Additional contests may be held for other shapes and
materials if there is sufficient interest and participation.

Values for ISO will be summed and used as ISO total.

by team of four judges selected by Jeff Ford or delegate/s.
all work must be done by one individual. In the
case of a fractional indices or an incomplete design a design
coach will explain how the problem can be fixed and the
entry will be moved to Coached class.
more than one individual from a club, guild or area may work together
as a team. If an individual wishes coaching they may do so
work must be done by the entrant with only suggestions by coach.

enter as your own. I encourage friends, club/guild members to enter
team. Do not hesitate to enter if you need some coaching. We have
mentors who are happy to help you.

gives you permission to use. You enter design with modified angles,

Design and Cut,
design will be posted and ISO Total noted but beauty of the finished
will be the judging criteria. Stones will be judged at the OPLC
Tucson. Individual, Team/Coached and Modified designs will be judged
I hope this format will encourage design and optimization
newcomers to get involved and hopefully develop their skills. All
entries will be posted on the site and may drive some traffic and
I think ISO Total is as good as any single value to evaluate design
performance but we will look to improve criteria in the future.
