Photo Prop Treasures – Part One

I got to thinking about the pieces of nature that I use as backdrops for the photos of the pieces I make.  Most of them are precious to me, and have little life stories behind them.

 

Pink Drusy Agate and Sterling Silver RingI found the piece of stone the ring is sitting on in this picture in the desert on a trip to Egypt.  One of the places our journey took us was to El Alamein, where parts of World War Two were famously fought.  As pictured below, the battlegrounds were basically desert, stretching on for miles and miles with no shelter and presumably very little water – it must have been a living (and dying) hell.  The area is still so heavily mined that it is impossible to use it for anything, and of course the Egyptian Government don’t have the financial ability to have the mines removed.  There is argument that the countries responsible for laying them should be responsible for removing them, which sounds like a fair call to me!

El Alamein Desert Battlegrounds

We went first to the German War Memorial, and saw the names of all the German soldiers who died there at El Alamein – most of them only about 20 years old. It was moving and saddening to think that each of the names we read represented the loss of life of a young man who didn’t necessarily want to be there fighting and killing, and that it also represented a lifetime of heartache for his family that were left behind.

After that we went to the War Museum, which was quite interesting, lots of info about the battle, and many examples of uniforms, weapons etc.  Little scraps of letters written to loved ones. Outside the museum had all the anti-tank and anti-aircraft guns, and personnel carriers and tanks and the like on display. They found a Spitfire in the desert in 1999, and that was there – they also recently found a big three tonne Ford lorry used by the Canadians during the war buried in the sand, and apparently when they turned the engine over, it still started! Ford wanted to buy the battery back, but the museum wouldn’t sell it.

We then went to the Commonwealth Cemetery and Memorial, which is a huge area of graves – of course, the casualties at El Alamein were nothing compared with some of the other battles, but it seemed enormous nonetheless!

I had been researching my family tree not long before we took the trip to Egypt, and El Alamein went from being the only place on our agenda that I didn’t really care so much about seeing to being a point of interest for me, as my second cousin twice removed (so, that’s my grandfather’s grandfather’s brother’s grandson – confused yet?  It’s quite a close family connection in genealogical terms, I promise! 🙂 ), was recorded as having died there at El Alamein. We found his name in the official grave register at the site, and recorded on the memorial wall, meaning that his body was never found so was unable to be buried there.

The register entry shows him lost in the SS Scillin – and the last battle in which he fought ended some days before the 14 November, which is shown as his date of death.  The SS Scillin was actually an Italian ship, loaded with Commonwealth POW, which was sunk by a British submarine. Poor boy, dead at 22, killed by his own side.  This information was only released by the British Government in 1996, so it is doubtful that his family ever knew what had really happened to him.  I wonder what they were told?  Regardless, I can only imagine how painful it must be to receive the news that your nearest and dearest has been killed in the war.

Anyway, I wandered around the cemetery reading some of the sad inscriptions, had a private cry at the tragedy and waste, and then went for a look at the Australian War Memorial, which is where I found this piece of stone, lying on some waste ground beside the path.  I’m not sure if it’s natural, or if it’s a piece of rubble from some old building, but it spoke to me and I brought it home.

Cuttlefish Casting

As part of the goldmithing course I did in 2012 I attended a weekend casting workshop. We did some lost wax casting (more on that later), and also some cuttlefish casting. Yes, really using cuttlefish! Or more correctly, their little (or not so little) cuttlebones.  I hasten to add no actual cuttlefish were harmed in the making of this jewellery – their life expectancy is around one to two years, they die soon after mating, and you can quite often find their cuttlebones washed up on the beach.

The procedure for cuttlefish casting is to cut the ends off the cuttlebone and cut it in half.  Grind down the two surfaces until they are flush.  Carve a funnel in one end of the two halves, and carve your design just below that.  Bind the sides together to form a mould, smelt your silver and pour it in!

Malachite and Sterling Silver Cuttlefish Cast Pendant

I cuttlefish-cast the bottoms of these two pieces, then set bezels with bails attached into the cast pieces to create pendants. One is set with malachite, the other with paua shell.

I had to hand these pieces in as part of my final presentation, and then they were sold from my online shop.

Pharaoh Cuttlefish

Cuttlefish are members of the cephalopod family, like ocotpus, squid and nautilus.  They emit a brown ink to help them evade predators.  This ink, known as sepia, was once prized as a dye. Cuttlefish have green blood, due to haemocyanin, which carries oxygen and contains copper, unlike humans who have iron-containing haemoglobin filled red blood.  Cuttlefish have beaks.  Cuttlefish have chromatophoric cells, which enable them to change the colour of their skin instantaneously.  Aren’t they wonderful!  And coincidentally in keeping with my (unplanned) marine themed year!!! Thanks, little guys!!

Sterling Silver Tablespoon

Forged Spoon

The lastest project for my goldsmithing course was to cold forge a sterling silver spoon.  Creating fine metal jewellery is called goldsmithing, and creating fine metal tablewear is called silversmithing… which creates some confusion!!!

Sterling Silver Tablespoon

Lots of hammering, some bending, doming, soldering and polishing later, and it was done.

I started out thinking I would make a metric teaspoon, then decided that was too difficult.  I measured the volume of the bowl of the spoon out of interest, and guess what?  It’s a metric teaspoon!!!

Silver

 

Raw Silver

Silver, fabulous silver! Silver is one of the ‘noble’ metals, meaning it is resistant to corrosion and oxidation in moist air. It is also a ‘precious’ metal – a rare, naturally occurring metallic chemical element of high economic value.

Silver is the 47th element on the periodic table. The chemical symbol for silver is Ag – from the latin word for silver, Argentum.

Fine silver is 100% pure silver. The sterling silver that I work with is made up of 92.5% fine silver and 7.5% copper.  The copper is added to strengthen the silver, as fine silver is too soft to hold a refined shape.  Silver is the second most malleable and ductile metal (the first being gold).  The specific gravity of silver is 10.4.

Fine silver melts at 961 degrees celsius.  Sterling silver melts at 893 degrees celsius, and it is annealed at 648 degrees celsius. Zinc is added to silver to make silver solder.

Silver is the metal with the highest heat and electrical conductivity.  It is used in jewellery, tableware, industry and for coinage.

 

Minerals and Mohs

Rob Lavinsky - Mohs Scale

Minerals are inorganic substances which occur naturally, which have a definitive crystalline structure and chemical composition. Rocks are made up of one or more minerals. In 1812, German geologist and minerologist Frederich Mohs came up with a way of determining mineral hardness. He devised a scale of ten minerals and ranked them by finding the hardest material that each given material can scratch, and/or the softest material that can scratch each given material. Other substances can be classed by where they fall on this scale. The scale is ordinal, in that each mineral is not exponentially harder than the last. Mohs Scale is:

  • Talc
  • Gypsum
  • Calcite
  • Fluorite
  • Apatite
  • Orthoclase (Feldspar)
  • Quartz
  • Topaz
  • Corundum
  • Diamond

In the jewellery industry, Mohs Scale is used in determining the identity and authenticity of precious gemstones.
