This is a picture of the largest Anode available from an electroplating supplier.
The anode is approximately four feet long and three inches wide, and is a dog-bone cross-section (that is, the edges are swollen to give a more even erosion pattern in use). The anode weighs 5.256 kg which is approximately eleven and a half pounds avoirdupois, or, if you want to be pedantic, just over fourteen Troy pounds. It is made of solid .999 fine Silver.
There is a metal 1-foot ruler beside it at the base for comparison.
I thought you might like to see a picture of it, before it went to the buyer. At current prices, I am told it cost £2092 plus tax (USD 3,115). The tax added another £420 (USD 625). It would be interesting to work out how many litres of CS it would make.
