Platinum ring

I hope I learnt a little bit more about platinum because of the construction of the ring. Platinum does not conduct heat so when sweat soldering the third plate of the ring together I melted it. I should have used an easier solder. Eventually I soldered a pin/rivet to hold the plates together. This is a perfect example of how this metal behaves differently to metals like silver and gold.



It takes a long time to clean platinum but the results are worth it.
