This is a recent commissioned piece - a Christmas gift for my client’s partner. I was going to mount the spring loaded clip holding the vial on a plain rectangular piece of brass.On a whim I held it over the copper ring that was on my work area. Although it’s quite simple I’m really happy how it’s turned out and will take this concept a bit further in the next piece. I’ve got to buy more tritium as I’m down to my last few sticks - just yellow and pink left.
