Wet Laying Enamel for Beginners
This is sometimes known as wet packing, but that name doesn’t indicate that on silver the layers should be as thin and even as you can make them. If the transparent enamel is applied too thickly, the reflective quality of the silver is obscured and bubbles are much more likely. Even with opaque enamel where transparency is not required, bubbles are an enemy, so always apply thinly.
After grinding and washing the transparent enamel you have to choose a tool for the application. The traditional one is a goose quill, but some people prefer a fine water colour brush. Metal tools are sold for the purpose, but they are not flexible as quills and brushes are. Which ever you choose, practice is necessary.
