The new porch extending over the original front door enabled a set of double doors to open into the entrance hall. Such an expanse of glass deserves a stunning statement and the 2 large central semi-oval bevels, framed by the painted lilies on a rich swirling blue background, certainly achieved this. The inspiration for the design came from some tracery windows in the local church and this was met with the wish for plenty of light admission.
New windows that are to be painted require drawing up full size into a drawing that resembles the finished piece in all regards but for colour. All painted detail is drawn onto this which the painter will use to trace through the glass to transfer the linear elements onto the glass. This also includes the visual lines created by the leads.
Tracing paper is then placed over this and the centre line of each lead is traced through. This forms the pattern that the glass will be cut to so that all the pieces fit together accurately.
Various paints can be used which will all be fired in a kiln. Finely ground oxides are used for the line work (trace lines) and shading (matting). This is usually the first paint to be applied as it forms the drawing and contouring of the objects. Coloured enamels can then be added if another colour is desired on 1 piece of glass. Silver stain is applied to the back of the glass which ranges from light lemon yellow to dark amber.
KILN FIRING – The various paints fire at different temperatures ranging between 590oC and 670oC (although all kilns vary) and so the paints which fire at the highest temperature are fired first. Several layers can be built up by alternating vinegar, oil and water mixes which can be all fired in one hit. The silver stain is the lowest temperature firing, but with skill and lots of experience, it is possible to achieve 6 or more layers of paint in just 2 firings.
