Etching

The hardest part is now done, and only the etching is left. I use either Natrium Persulphate or Ferric (III) Chloride. Natrium Persulphate is more sensitive to temperature and should be warmed till around 40-50 degrees centigrade. If it is too cold, the etching process can take ages. Ferric chloride is not so temperature sensitive, but you can't see anything during the process, as it is not transparent. I have built a small vertical container for my etching as plate, as ideally this should be placed in a vertical position. Depending on the temperature and thickness of brass or copper, the etching process will take around half an hour. If the solution is stronger, that time could be shortened.

And here are my photo etched letters already attached to the bulwark. They look fantastic!
