It has taken Gerry about two hours to work out how the pattern on the Iron Age vase might have been drawn.
He transferred his drawings from paper onto the pot and traced out the design. Then using a cobalt and copper mix he painted the pattern over the red slip.
There is a little gap of unglazed pot before an application of copper/cobalt mix along the rim and the bottom - then a key shapped pattern just above the shoulder.
It was only when it was finished that Gerry realised that the spirals he has painted on face the same way, whereas on the original vase, they alternate. Never mind, I'm sure the Iron Age people had to practice too - and he has made a spare to get it right!
