OUR NEW QUARTZ BOOK

OCTOBER 13, 2014

I AM IN THE PROCESS OF FINISHING UP A NEW QUARTZ BOOK: FROM ONE QUARTZ CUTTER TO ANOTHER. I WILL WRAP THIS PROJECT UP ON NOVEMBER 25, 2014 AND HAVE COPIES READY FOR SALE. THE BOOK WILL BE IN .PDF FORMAT ON CD-R AND THERE WILL ALSO BE .GEM FILES FOR ALL THE DESIGNS.
THE PURPOSE OF DOING THIS IS THAT IF OWNERS WANT TO TANGENT RATIO SCALE A DESIGN FOR DIFFERENT MATERIAL THEY CAN EASILY ACCOMPLISH THIS IF THEY OWN A COPY OF GEM CAD FOR WINDOWS.

THIS WILL MOST LIKELY BE MY LAST FACETING BOOK AS I HAVE ACCOMPLISHED MORE THAN I EVER IMAGINED AND IT IS TIME TO WORK ON OTHER ARTISTIC ENDEAVORS.

THE PRICE WILL BE $30.00 INCLUDING USPS WITHIN THE UNITED STATES.

I INTEND TO MAKE SOM...

TILT LIMITS FOR WINDOWING

By Jim Perkins (with Bruce Harding)
Copyright 2010

I am often asked how to choose good angles for faceting. Some of the answers were published in 19751 and are now available on the Internet at the address provided in the footnote.  One subject is ‘windowing’, which means that light passes directly through the gem without internal reflections; generally when the table is tilted from ‘normal’ (perpendicular) to a line from the viewer’s eye.

This was discussed in the subject article2, which provides charts for common materials. Each of these lists pavilion slopes across the bottom, and the maximum angle of tilt without windowing is listed across the top. Since nothing else matters in the subject of windowing, these data can be listed simply as below:

WHAT MANY PEOPLE DON’T KNOW ABOUT GEM DESIGNING.

Sometimes I think people think I simply wave a magic wand over the front of my computer screen and a new faceting design appears.

To create designs is 90% perspiration and 10% inspiration. Anyone who says differently is simply wrong. Some designs come easy and just seem to fall in place. Other designs will be long drawn out affairs which may span several weeks of hair pulling agony before they seem to work themselves out.

Sometimes I will awake from a sound sleep and be driven to the computer to design. A friend of mine says the MUZE visits me in my sleep...
