Here is a simplified overview of the long and complex process of making this piece. I have not included everything, we use a lot of traditional skills and a variety of machines which have been built or modified specifically for us. Most of this engineering I do myself, I will put more photos online and some videos (current ongoing project is 30" blade diamond saw).
  • Sheet glass is cut into strips then printed or painted with rubber printing blocks in a method similar to Indian traditional printing. This technology was developed by Jenny.
  • Detail of printing methods. The paint used is a ceramic material modified with flux.
  • Highly complex lamination, using dichroic glass. It takes about a day to do each layer and we have been developing this method alone for a year or two (not forgetting the 30 or so years it took to get this far).
  • Precarious lamination in kiln, upside down which is another recent development requiring complex mathematics, logistics, fine balancing, cutting and assembly. Ignoring the development time so far this has taken about 2 weeks or so.
  • Final assembly with complex counter weights, which was developed after looking at cantilever architectural methods of cathedrals etc.
  • Our firings are long and technically demanding, the maximum firing temperature is around 900°C.
  • Out of the kiln the piece weighs approximately 20+ Kilos.
  • The glass has been roughly chiselled to shape using a special pitching chisel. This photo shows grinding / flatting on flat bed.
  • Grinding the edge with a diamond wheel lathe,  not really visible is the sling counter balance to take weight off heavy piece.
  • This shows the piece ready to wax up prior to polish.
  • This shows pieces waxed and polished. For every polished side, the piece will need to be reset in wax.
