Re: [meteorite-list] Point of Diminishing returns (Slice thickness)?

2011-03-08 Thread al mitt

Greetings,

Interesting discussion on meteorite thickness, weight, value and slices etc. 
and so on. My problem with cutting slices too thin are many. While you get a 
great looking slice with good surface area there are trade offs. Number one 
is there is more breakage when trying to cut ultra thin slices. Breakage 
should cause the price of the material to rise, if you have a truly limited 
amount of that material in the first place.


Two. Thin slices that are made without breakage are also prone to breaking 
later on. It could break during shipping to the buyer. Breaking a full slice 
can reduce the value of that slice, especially if there are only a couple of 
full slices in the world of that material. Even if you don't break it if you 
sell it later there is a chance it could break in shipping. You can always 
sell the two half slices and the multiple crumbs then.


Three. Another consideration is if the surface of the slice needs 
refinishing at some point (even if it is not in your lifetime) the odds 
again are higher that it will break while being worked on. A thicker slice 
can be resurfaced multiple times assuring it survives being studied, viewed 
and appreciated in the future.


Four. Cutting specimens ultra thin causes waste of material. First you get 
more slices but at the lost of more material. One commenter mentioned 60% 
which sound right to me when cutting ultra thin. Again if the material is 
truly very limited, scientifically valuable material could be lost. I can 
appreciate cutting material where there is lots of that material and to cut 
ultra thin as there will be multiple kilos of it for sometime.


For those who collect thin slices I am not picking on you but just posting 
my thoughts of these ultra thin cut slices and the pros and cons. Please 
don't take it personal. I do have some ultra thin slices in my collection.


I coined the phrase that I am the current caretaker of the meteorite 
specimens I currently posses which will be past on to future generations. It 
is my job with that collection to try to preserve it best I can.

And to Capt'n Blood's point, reviewing some of my early purchases, cube-form 
non-end-cut, I wonder what I was thinking then...and then I remember, I was 
learning about each class, wanting to see each from a 3-D angle.  Things are 
different now (but the intrinsic value of that perspective rings true, 
still.)


So there is validity to each presentation, depending upon from where we all

Hi Micheal and List,

The first question I am always asked is  "what is your price per gram?", not 
"what is the surface-to-weight  ratio or the dimensions", for that matter.  The 
dimensions are only asked for after the price per gram question 99 percent of 
the time.

I will always choose  the most attractive piece that was well prepared over 
some 
block-cut  monstrosity without any polish any day.  The problem is that a lot 
of 
dealers/collectors  trade meteorites like they are commodities, not the true 
rarities  that they really are.  The rules have changed the last few years 
making the  price per gram the number one issue when shopping around.

The  key is learning a balance which is different for each and every  
meteorite.  I am still learning this balance after preparing well over 35,000 
specimens.


Best Regards,

Adam

Re: [meteorite-list] Point of Diminishing returns (Slice thickness)?

2011-03-07 Thread Martin Altmann
I know many collectors,
who prefer thicker slices, to have a little more an impression of the
exterior of the stone,
..and in fact, whenever they could afford, they will choose endcuts,
because there you have something in the hand, you see how the stone
originally looked from outside

and - especially compared to ultrathin slices - an endcut is made for
eternity.

And there are the problems, if you cut a stone slice too thin, you can't
grind and polish it anymore.
Perhaps you know these wire cut ultrathin stone slices, they have a huge
surface/weight-ration but often they have that wavy relief from cutting,
which you can't remove anymore, because the slice would break into pieces,
if you'd try to grind it.
 
And if you have a too thin iron slice and you'll get problems with rust, it
will be extremely difficult, if not impossible, to refinish and to re-etch
it. 

Nja well, Mike, from which thickness/cut loss on a slice becomes more
expensive per weight,
that is in practice alone the problem of the preparator :-) - because in the
end the collector decides, whether he would be willing to pay a higher price
per gram. (And I tell you, most won't).

Best!
Martin

Re: [meteorite-list] Point of Diminishing returns (Slice thickness)?

2011-03-07 Thread Adam Hupe
There is a point that a specimen will easily break if cut too thin.  Some 
material can be cut to 1mm thick but cutting losses can mount up to over 60% 
even when using a wire saw after applying a polish. We had over 50% cutting 
loss 
on Martian meteorite NWA 1195 which was cut on a diamond wafer saw and then 
diamond lapped on both sides. I think a 2 to 2.5mm cut is reasonable on most 
ultra rare material if polished on both sides.  The thickness has to be greater 
on friable material like Nakhlites otherwise you will receive a pile of crumbs. 
 
It also has to be thicker on large specimens to support the weight on a display 
easel.

Most collectors go by the price per gram first so dealers who cut ultra-thin 
will take a loss when weight is the main consideration.  I know that the 
weight-to-surface area ratio is a secondary consideration for most collectors 
due to experience.

There are other factors like a decent polish being applied, proper preparation 
and specimen status including provenance that can affect price.

Adam

Subject: [meteorite-list] Point of Diminishing returns (Slice thickness)?

These discussions about aesthetics of specimens vs their weight is rather 
interesting, but it seems the lines of the subject are a bit blurred.

It seems the subject has come to comparing fragments to slices. I'm not sure 
this is a fair comparison, but I understand it.

I am wondering what others think represents a point of diminishing returns in 
making a slice paper thin. IOW at what point does cutting losses become too 
great to make the aesthetic function of the prep & price excessive?

I guess I don't understand the desire for some ultra-thin prepped specimens. 
For 
example, if a ultra-thin 1mm thick slice is being sold for the equivalent $80 
per gram, and a slice of the exact same material, the exact same size, but 4 
times the weight (4mm thick) is being offered at the exact same price, I'd be 
inclined to purchase the latter.

I understand the appeal of of thinner specimens and of course you can polish a 
slice so finely it becomes a thin section, but is there some point where the 
prep becomes so costly that is is in fact "too thin" for the buyer?

Thanks

Hi Richard,

I lack the skills and equipment to produce paper thin slices.  I have
only seen a few slices less than 1mm thick that were not too fragile
to handle.  As a collector, my preference for thick versus thin varies
from specimen to specimen and type to type.  Some types I would prefer
a thin slice that shows lots of surface features - like an expensive
brecciated fall or a pallasite.  Other times, I would want a thick
slice with a complete rim of fusion crust along the edge.  So I don't
have a strong preference one way or the other.

A while back, I purchased a thin slice of a Martian.  It was paper
thin and certainly less than 1mm, and it was almost transparent.  In a
membrane box, I could hold it up to a bright light, and it would glow
beautifully.

As a cutter, if I am using a super-thin .006" blade, the amount of
cutting loss is negligible to start with, so making thin slices is not
so much a matter of loss as it is labor and precision.  Super-thin
slices tend to break easily, either during cutting or during polishing
afterwards. The vast majority of my slices are 1mm or thicker - I have
a poor track record with trying to make the very thin cuts.

Best regards,
