John R. Neill drew a vivid image of the whirlpool, complete with sea nymph rising from the foam. About a year and a half ago, I drew this up to be made into a stained glass window, and it has finally been produced.
Here are a series of photos showing the procedure for creating the window.
The first step is to draw the full size pattern, or cartoon, for the window. This obviously was based on Neill's illustration. We then color in the cartoon to help differentiate areas of the window - the color scheme isn't always what we intend for the final piece.
We cut and fit the glass, and the face and body pieces are painted and fired in a kiln. Glass paint is actually powdered minerals, mixed together with certain oils, or in this case with water and gum arabic. Each layer of paint is fired before applying the next. This picture shows 3 palettes of paint, and the glass muller which is used to grind and mix the pigment.
After cutting and fitting, each piece of glass is wrapped with a thin copper foil. This will hold the finished window together.
