Last year I was given the opportunity to cut a cabochon to order for
Belinda Newick. She was producing some beautiful forms for the up coming celebration of The Jam Factory turning 40 and wanted a piece of nephrite jade to be included.
The exhibition, Designing Craft/Crafting Design has had such a positive response that it will be
touring Australia! They have also constructed a separate
website for the occasion. I am pretty excited about this as I will actually get to see the exhibition in person when if eventually comes to Victoria (Yay!).
I must admit to having some nerves along with the excitement starting out on this adventure having never cut anything to order before.
I LOVE cutting cabochons as I find it SO relaxing. It is noisy, messy and thoroughly satisfying! You start out with a hunk of rock or stone and finish with something that can be set into jewellery or simply be displayed and admired. Cutting to order was very different than cutting for myself. I noticed that I took more time on each stage and checked the progress a lot more frequently! lol
Belinda need the nephrite to be a specific shape and size so we met to discuss the brief and for me to collect the piece she had selected to be cut. I got to handle one of her silver forms and the shape was ridiculously tactile. It seemed to nestle into the palm of your hand and warmed to the touch beautifully.
I took many photos during the cutting (but still somehow missed a few stages) so here are the phases of cutting a double sided free from cab:
First step is to mark out the outline of your shape onto the slab. This is done with a sharpened 'stick' of aluminium then sprayed with hairspray to fix it in place. Due to the dark green of this piece I instead used a fine tip permanent marker. A diamond saw is then used to trim off any excess.
Next onto the grinding wheels
From here you need to be able to manipulate the stone on the grinding wheel on various angles so to achieve this it must be mounted onto a dop stick. I marked out some general guide lines and proceeded to warm the piece of nephrite to help the wax adhere to it. At this stage it is very chunky and took a very long time to warm up!
To remove the nephrite from the dop stick you simply cool it making the wax brittle and 'snap' it off. Some times it simply falls off in the cold. I repeated the cutting and re doping of each side a few times as I wanted them to be nice and even.
In the background you can see the various grinders of different grades along with the mess you make!
At the
clubs rooms the lights are long fluorescents. One of the other members taught me to use the reflection of the lights on the piece you are working on as a guide to see if there are any flat spots/if your curve is even. In this photo you can see where I need to do some more work.
I missed photos of the sanding phase but in the above two photos you can see on the left the sanding wheels. They are wheels that spin clockwise or anti-clockwise and have various grades of wet/dry sandpaper mounted on them.
This is the stage I handed the nephrite over to Belinda - though I admit I miss handling this lovely piece! The shape she chose is so lovely I am sure who ever becomes the lucky owner will constantly be holding it.
She then engraved it giving it its finishing touch.
The above photo is taken from the Jam Factory's website showing it along with Belindas other forms made from; pine, yellow gold, copper and silver. I think they look fantastic together and I am so thankful to have been given the chance to play a small part in this.
Thank you Belinda for the opportunity and also for the permission to post photos! It was a really enjoyable experience :)
If anyone has seen this exhibition or has any questions on cutting/lapidary please fire away. Comments and questions welcome!
