The process is quite simple, involving the scraping away of the leaf, to expose the black boll underneath, using a scribing tool, rule and compass. Having said this it requires a good eye, a steady hand and a great deal of patience and care. One of the 330 diameter round clock dials takes around three hours to etch. It’s slow but enjoyable work -especially with Radio 4 to keep you company.
I have tried screen-printing on the numbers, which is a lot quicker and easier, but the numbers do not look right. By etching the numbers they appear more in keeping with the hand made character of the piece.
