The silicone key is the stencil for creating the new molds correct shape.
 

This is the draft for the new mold...........
 

 ....which is made from plaster to be duplicated by my fiberglass company after it has been polished.
 
 

The fiberglass mold is completed here and some of  the original glass pieces (which were

included with the lamp) indicate that the shape is correct.  The original lower rim also fits perfect.

The lamp shade can be brought to new life on this fiberglass mold.
 
 

Here the original pattern is scribed on the mold.
 
 

We have engraved the lines and transferred the  pattern on paper.

This will be used for our 360 degrees layout we need for our Studios light table later.
