Subject: TANZANITE HEATING INSTRUCTIONS
Date: Fri, 25 Oct 2002 04:51:10 EDT
To: faceters@caprock-spur.com
From: Bellcha7@aol.com

Most Tanzanite should be heat treated after being cut.After you have cut your
gem,and after you have removed all the inclusions,Heat the gem in a Burn Out
,Casting Oven.
First place you finnished gem in DRYcasting investment,leaving about 1(one)
inch of investment as insulation on all sides of the gem.(more than one inch
is fine)The source of this info uses an old coffee can,fill it with
investment,and just place the stone in the middle.Then:slowly,over a 6-8 hour
period , raise the temperature to about 1000 DEGREES fahrenheit.Hold this
temperature of about an hour,then let the stone cool down slowly in the
oven.The source of this info recommends you start the porcess early in the
morning,then about 5:00-6:00 p.m. turn off the oven.By the next morning the
oven hould have cooled down,and you can remove the finnished
TANZANITE.

Hi Everyone:
 
I want to thank those of you who have sent me an email with your suggestions
and comments regarding the establishment of a Faceters Museum and a Hall
of Fame for faceters. 
 
Please send me your suggestions or ideas for such a project anytime in the
next six months period of time.  I will be happy to be the receiver of such information
until a more permanent arrangement can brought into being.  Do not send me any
faceting machines, equipment or large items, because I do not have the space
available to collect and save these items.  I can certainly handle any emails,
attachments, or printed articles that you may think would be important to the history
of our hobby.  If you know of equipment that should be displayed in such a museum
someday, please let me know just what the articles are, or a written word of why
such articles should be part of a faceters museum.  As I stated about ten days ago,
I have two very special early UltraTec machines that would be donated to the
museum, and I will keep looking for other brands of early machines or one of a
kind homemade associated equipment.
 
This project cannot happen overnight, it will take months or years to come to fruit.  
But I feel sure that we should all be aware of the fact that our hobby, although
recent in time (some fifty years approximately), we should be collecting the old
equipment and articles that have made for the great progress in faceting the last
half century.  I expect faceting to grow greatly in the next half century.   Although
I will not be there to see that progress, I want to do what I can now to see that
the work and effort of early faceters is not lost by those who will follow.  Faceting
is a hobby that takes more concentration than a lot of other hobbies.  Faceting
also is very  rewarding, as we see the fantastic improvement that our flat facets
make on a piece of rough Cubic Zirconia.  We accomplish our work by taking it
just one facet at a time.
 
One of these days a proper place will be found for the Museum and Hall of Fame. 
Until the right people come forward to make it all happen, please, all of you faceters,
keep your eyes and ears open to arrange for historic faceting equipment and articles
to be saved...not forever lost.

Greetings from Western Pa. Winter is just about upon us and I for one am
getting ready for a long cold winter, with a lot of snow. So, I am looking for new
projects that can be done indoors where I can keep warm. As a long time
facetor, just as a hobby, I have a good quanity of cut colored stones that need
setting. What I need is a good book for wire wrapping. I want something that is
slanted more to gemstones and not just making wire jewelery without a gem
included. Does any one on the list have a recomendation for a good beginers, with
designs included, book that a novice can learn how it is done?
