Murrine

 

Murrine are slices of glass cane containing a representational image inside,
revealed when cut in the cross section. Many slices of the same image
may be cut from one length of murrina cane.

Moasic vs. Torchworked
 
  Mosaic Murrina Torchworked Murrina  

 

We use two methods to create glass murrine images. The Mosaic murrina is built with cold threads of colored glass, whereas the Torchworked murrina is sculpted from molten glass in the flame of a torch.

The Mosaic Method: (sometimes called stringer-stacked)
We build a murrina in a metal cylinder by arranging colored strands of glass, usually a millimeter in diameter or less, in accordance with a pattern at the back of the cylinder. Zachary hand mixes the colors and pulls all the strands in preperation over a few weeks. This method lends itself to extreme accuracy, pointilism, some pixelization, and photographic quality.
It takes aproximately two to three months to complete the mosaic, which we then fuse into a solid cylinder, melt it with the torch to work out the bubbles, then heat and stretch it down smaller and longer.

 

 

After annealing in the kiln we cut the stretched cane and polish the slices, which are then encased in marbles or presented individually. End-of-canes from the second, smaller pull are cut and polished from each end of the stretched murrina.

The Torchworked Method:
Torchworked, lampworked murrine was taken to the highest level known in history in the mid 1800s by Giacomo Franchini with several complex portraits he made on animal fat burining lamps, mixing his own colors. While technology and equipment have advanced, we also work in a fairly similar method today, sculpting components such as eyes, nose, mouth which are strecthed in the flame to the correct size and added together in the flame. This method is extremely challenging to achieve correct proportion with minimal distortion. The liquid nature of hot glass lends torchworked murrine its characteristic look with smooth transitions, smooth lines, and the feeling that it has been created hot, in the flame, alive and active.

 

 

       
Once all of the component murrine have been added together in the flame, the finished murrina image undergoes the same heat stretching process described above.


Millefiori

Millefiori, literally meaning thousand flowers, are any of a group of abstract pattern canes, often including numerous components stretched and regrouped many times to resemble a flower structure or other design. These are also cut into small slices or chips, the decoration revealed in the cross section.
