Tut's gem hints at space impact

The customer insisted it was a tektite, but we listed it on the
document correctly. 

Correctly meaning glass? and to clarify my question a little… I
was referring to faceted moldavite. African in particular. The ones
I’ve seen have not been opaque – neither Czech nor the lighter
variety although I must say that I wasn’t particularly attracted to
the Czech variety so I wouldn’t have looked under a microscope. Based
on your post then, if one of these is faceted, all I could hope to
find would be striations and air bubbles? I’ll have to take another
look when I get to work today. Thanks for the info.

Yeah that’s what I said not Lisa…phoenicians very long time ago
that’s why we call em ancient lol and 4000 year old bottles hand
blown and very cool recent finds…Hey I was a Fine Arts/
Archaeology (palentology) dual major in college so what can I
say…lol

As well as a possible tektite could it be a fugelite formed in a
lightning strike? 

Webster’s; fulgurite: a vitrified crust produced by fusion of sand
or rock by lightening.

The fulgurites I have seen,and the one I own, look like sand and
rock that had been glued together. Did not look like glass in any way
shape or form.

Correctly, meaning moldavite, not tektite. And my post said that
moldavite is transparent yellowish-green, not opaque. Also, I didn’t
say that “all you could hope to find would be gas bubbles and
striations,” but I did mention them as a diagnostic property. Many
faceted moldavites will have no gas bubbles or striations, others
will have them, and more. It can be the same with manmade glass or
other types of natural glass, including the metamorphic ones, like
obsidian. Base whatever you wish on my posts, but please make sure
you base it on what I actually do post.

Appraising a moldavite, rough or faceted, and listing it as “glass”
would be as improper as listing obsidian, monkstone or Swarovski
crystal as “glass.” It would also be as improper and incomplete as
listing an emerald, heliodor, goshenite or morganite simply as
“beryl” would be. Or amethyst, citrine, agate, or even opal simply as
“quartz.”

Um...Judy? I believe you are confusing me with someone elses post.
I never mentioned Phoenicians, only Egyptians. 

Lisa, my reference at this point was not to your post but to the
link you provided on the history of glassmaking, which, I suggest,
does not clear up the mysteries involved here.

I should have added that the references to 4000-year-old glass
bottles and Phoenicians were from the post of Teri who was
“twitching in Pittsburgh.”

That said, apparently Phoenicians did have clear glass...please
see: http://tinyurl.com/kbmo8 and Phoenicians were around since
approximately 3000 BC, http://phoenicia.org/history.html so if you
are insisting that Phoenicians didn't appear until 1100 something
AD, it will be news to them. 

The problem here is only the “date” of the Phoenicians. In the
second of these internet sites, their first paragraph pretty much
agrees with what I said in my post about the origins of the
Phoenicians:

the term "Phoenician" is now normally applied to them in the Iron
Age (beginning about the twelfth century B.C.) onward when the
traits that characterize Phoenician culture evolved: long-distance
seafaring, trade and colonization, and distinctive elements of
their material culture, language, and script. 

If you wish to discuss whether the people known as Phoenicians were
identical with the Syro-Canaanites who may well have moved into the
area around 3000 BC (as your internet sites says), perhaps we should
do that off-line! In any case, my dates for the Phoenicians were all
BC, not AD. I also did not “insist” that the Phoenicians didn’t
appear until 1100 – all I did was report on the writing of a scholar
whose life-work has been the ancient history of that area (Edward
Lipinski, in the Sasson volume).

This brings up another issue – the reliability of internet sites,
which often do not tell you who wrote something, what their
background is, what their evidence is, where and when they got their
from, etc., etc. That’s why I cited the Sasson volume and
the Moorey volume – they provide that kind of Since I
have a background in science, I am always most interested in primary
(not secondary or tertiary) evidence.

In any case, if the person who wrote the next paragraph in your
link:

The Phoenicians, whose lands corresponds to present-day Lebanon
and coastal parts of Israel and Syria, probably arrived in the
region in about 3000 B.C. 

wishes to call the Syro-Canaanites of 3000 BC “Phoenicians,” I can
only say that is their personal preference but not one which
historians of the Ancient Near East would agree with.

As for the nature of “manufacturing,” I disagree with your
generalization on the need for civilizations to grow enough for
demand to develop:

"widespread manufacture" is a rather obfuscating term during this
era, as true "manufacturing" wouldn't have become "widespread"
until civilizations grew enough for demand to develop. Apparently
that was about 1500 BC 

The civilizations of the Fertile Crescent, especially Mesopotamia
and Egypt, had been large and widespread (on and off) for at least
1500 years before 1500 BC. Mesopotamia had mercantile trading
colonies in upper Syria in the fourth millenium BC, and the Sumerians
had factories for manufacturing the textiles they traded for raw
materials, in the third millennium.

Also, the reference to the oldest known glass being from Egypt of
around 2000 BC (from the Bartleby link):

Ancient Glassmaking The place and date of origin of manufactured
glass are not known. The oldest known specimens of glass are from
Egypt (c.2000 B.C.), where the industry was well established c.1500
B.C. 

is simply incorrect. Moorey (1994: p. 190) says: “Since Beck’s [C.
W. Beck, “Glass before 1500 BC,” Ancient Egypt and the East, 1934;
pp. 7-21], fundamental review of the evidence, published in 1934,
there has been remarkably little progress in the study of the
earliest glass reported from the Near East, though the database
slowly increases. Beck was able to list only seventeen objects, not
all of them of certain date, and not one of them a vessel, made
before about 1500 BC in Egypt or the Near East. Although the list may
be lengthened sixty years later, there is still no firm evidence for
vessel production before the middle of the second millennium BC. Most
of the early specimens were, and remain, beads found singly or in
relatively small groups. None of Beck’s examples, nor any of the
subsequent finds, may confidently be dated before the middle of the
third millennium BC. Beck’s main conclusion, that regular glass
production originated in Western Asia rather than in Egypt, has also
stood the test of time…”

Ah well, this is getting convoluted and probably of lesser interest
to the Orchid list! But I always love folks who are interested in
ancient history!

All the best,

Stanley et al,

Professional lapidaries are all (well, mostly) quite aware that he
African material sold as “Moldavite” or tektite glass is actually
re-melted green bottle glass. Every time, all the time, I don’t are
what the “dealer” told you. While there are tektite occurrences in
Africa and all the other continents as well, the material is not
worth cutting as it is opaque or nearly so. Some of the old
Moldavite (from Moldau area) is facetable, but is not impressive due
to heavy flow stucture which inhibits brilliance.

This scam has been going on continuously since before 1967, when I
did graduate school research on tektites. I am a professional cutter,
and never fail to call out a dealer on this scam at the shows, but
they always offer some vague excuse like they “Trust who they got it
from” or “this material is different”, etc. I’ve heard every story
you can imagine.

It is not possible to go on a quest for gem material in Africa
without being offered some of this re-melted pop bottle stuff,
broken up and partially tumbled. It’s everywhere and there’s a
hopeful sucker born every minute.

This is not unlike the “Mt. St. Helen’s Emerald” material, which is
simply a borosilicate, lab made glass, made just like every other
colored glass, and annealed (usually) after manufacture. There is
ZERO ash from Mt St Helen’s in this stuff. I lived there, I know who
made this stuff and who is still making it,and they used to laugh
about how poplar it got back in the early 80’s. No ash, none,
period. It’s been tested to death.

But, watch, there will be vehemnet cries of denial to this post, all
incorrect and misguided and just hopeful or embarassed. BTW, yes, I
cut plenty of it, and told everyone what it was, they did not seem
to care…and I still have plenty of it to satisfy the occasional
person who wants a part of history, but…it is glass, made in
Washington.

Years ago between wars and several wars ago, in Lebanon and Syria
the glass artifacts were called “Roman” glass. This struck me at the
time as pretty weird-- where were the Phoenician glass artifacts?? I
didn’t buy any - not much money.

I see my across the street neighbors are just back yesterday from
their annual vacation in Beirut- haven’t seen them yet.

jesse

Well heck Judy, I was kinda thinking that the Columbia Encyclopedia
seemed a pretty good reference book, even if it was on the dreaded
internet…that was the Bartleby site, and you are right, I do not
know who wrote the Columbia Encyclopedia…but as you are of the
opinion that some other book that you have read is more correct…
("more correct…? is that even possible?), then I will defer to
save further argument. I just hope that you are not trying to tell
me, or even imply, that extra terrestrials aka…little green men,
made all of the little green bits of glass in the Egyptian desert,
because regardless of degrees earned or reference books read, I am
just going to LOL.

Simply because we can’t explain something does not mean that it is
unexplainable, or explainable only by magical mystical, or alien
divinations. It just means we haven’t either discovered or processed
all of the yet.

Wayne:

So R U saying that all (or most) of the moldavite I see at shows is
not moldavite at all, but glass? Wow, I mean, reading your post
that’s obviously what you’re saying, but I’m amazed… what a scam!
I’ve never bought any of it (by & large my customers aren’t “New
Agers”), but since there are some pretty large companies out there
marketing / selling it (don’t know how big they are actually, but
they put out a pretty d-mn big new age catalog–goes by the name of
"Heaven & E _ _ _ _ ") I just assumed that it was natural. You know,
it’s amazing how many hucksters there are in the new age/holistic
market. I’m sure many are sincere, but a heck of a lot of charlatans
(sp?) mixed in.

Doug

Hi Doug,

So R U saying that all (or most) of the moldavite I see at shows is
not moldavite at all, but glass? 

That’s what he’s saying, yes. It’s another example of the whole
‘naming convention’ thing.

Doug,

Czechoslovakian Moldavite does, of course, exist. It’s identity can
be proven by spectroscopic analysis, but not visually. A melted
glass is a melted glass, regardless of whether it was formed by
meteoric impact on Earth, expulsion from the lunar surface by
meteoric impact, or cooked up in a kiln somewhere. Unless one has a
GREAT deal of experience in handling these materials,
differentiation can be difficult. But truckloads of this material in
facetable form (any transparency whatsoever) do not exist. I have
seen some Thai material that is transparent, but it is very dark and
would not facet well, except as a curiosity piece.

True Moldavite (so named because it was first discovered near
Moldau) is believed to be a by-product of the impact even that
formed the gigantic Ries crater in Germany. As such, the melted
glass reflects the chemistry of the original rock in the area, which
is why spectroscopic can be characteristic.

And, yes, most of the Moldavite offered at the “gem shows” over
these many years is simply re-melted green glass. It is a veritable
village industry in parts of Africa and one simply cannot offer to
buy gem material there without being offered little parcels of green
glass melted yesterday from pop bottles. If you cruise the net for
faceting material, you will find many dealers, some of them having
been in business 30 years or more, selling this material. Some even
go so far as to say “This might not be natural” or some such thing.
Yes, there are lots of people selling this material, and the new age
market is ripe for this sort of stuff.

It’s exactly the same deal as the Mt St Helen’s “Emerald”, which is
still being sold in rough and faceted form, with the seller claiming
it is made from the ash from the eruption there in 1980. FGA says
the the composition doesn’t match. GIA says the composition doesn’t
match. If you melt the ash in the presence of oxygen, it turns dense
black. If you melt the ash in the absence of oxygen, it turns opaque
brownish black. If you add an eighth of a teaspoon to pure silica
and potash and melt it, it turns black. If you try to use it as a
glaze on pottery, it turns black. And I KNOW the individual who
makes this tuff and he LAUGHS about it.

Folks can believe what they wish, but…

Wayne

Wow! There are several companies that I know of that sell nearly
nothing but Moldavite, and another, Heaven & Earth, that markets it
pretty hard (or at least used to). Scammers really rub me the wrong
way & get my craw up. If I knew for absolute 100% sure I’d probably
heckle them the next time I see them…

Doug

Doug,

Moldavite is a natural material, happening to be glass; that is, the
Czech Moldavite. The Libyan Desert Glass is also natural material,
happening to be glass, from the Great Sand Sea in Egypt. Both are
considered tektites, eventhough there is mystery surrounding the
origin of Libyan Desert Glass.

Obsidian is a natural material, happening to be glass; originated
from volcanic action.

I think they’re all pretty fabulous in their own right. Get a hold
of a few pieces of each and let personal experience be your guide to
purchasing a good amount. An honest vendor will help in the quest.

Eventhough it’s glass, I’d love to have been the one that discovered
the fact that Tut had jewelry made with the desert glass. Bet it’s
pretty pricey, now!

It’s all relative.

Kay Taylor

Wayne, et al,

And, yes, most of the Moldavite offered at the "gem shows" over
these many years is simply re-melted green glass. 

Does this include the non-facet grade material? I bought a couple
pieces of Moldavite that are semi-translucent with irregular organic
surfaces (sort of botryoidal). Do I have to question the origin of
these specimens as well?

Beth

Hi Doug,

I have seen the material from the company you mentioned many times.
IMO, the material they sell as Moldavite from the clasic locality
is, in fact, just that. They would be more than happy to verify the
facts as I stated, as I’m sure they are as dismayed as the rest of
us at the scammers who operate so freely.

Wayne

Hi Beth,

The material with ablated surfaces is probably tektite material.
Moldavite is properly reserved for the translucent to
semi-transparent tektite material from the region around Moldau,
Czechoslovakia. Kind of reverse-botryoidal, almost like a coarse
sponge that has been parially melted.

There’s plenty of natural tektite material, just that the clear
green stuff is most often just ordinary glass.
