Oil and Cold Wax
Inbetween the more detailed pieces I like to create something freeing and fun. Oil and cold wax is great for this especially if you have left over paint on your pallet.

The Process of Fused Glass as Wall Art
Catherine's pictures have become popular locally and in Europe in the last couple of years, with commissions being ordered regularly of scenic views, depicting canals, lakes and recognizable landmarks.
The unique process has been developed over time and one picture can undergo as many as four, twelve hour kiln firings.
Glass is layered up and then fused together, the slightest gap or uneven layer can crack the glass, leave a fault, large bubble or skew the image significantly. There are many types of glass that can be used. Each type of glass has a different type of Co efficientency 'COE' and therefore it is important that only the same kind is used each time. A glasses' COE determines the speed and temperature at which the glass will heat up, melt and cool down (Anneal).
An example of this is, if using bullseye glass with a coe of 90, then it does not matter if you pile it high or spread it out, the glass will suck in or spread out to reach a thickness of 6mm on a full fuse. The outcome of an image has to be planned carefully before hand.
Often Catherine will make her own glass that will result in interesting designs and effects. This makes the artwork unique with one off never to be seen again glass.
Some glasses are reactive as they contain copper that will react with other glasses that contain copper. This can change the colour and outcome during the firing process.
Metal and paper and other things are melted and used as inclusions within a picture to give that extra creative look and feel to a piece.
Detail is added using powdered glass of different thicknesses and by using glass enamel which is also very fine powdered glass.
Wall Art and Glass Paintings
Catherine's artwork has being displayed in art magazines world wide and she is due to take part in the Bezel Art Week in Paris in October. She also has a solo exhibition coming up. Watch 'the latest news' section for more details.
Her art work is created using many 12 hour firings, applying layers of coloured glass and glass enamel detail.
Some of her work may include metal and murrini inclusions, apart from that the works are made up entirely of glass.
