This is a style of enamelling, whereby transparent enamel is used to fill holes / hollow shapes, giving a stained glass effect. The sample opposite, shows a simple piece of copper jewellery, with holes / hollows filled with transparent enamel. | ||
The hollows / holes of the annealed copper blank, are cut with a piercing saw. Needle files are then used to smooth the edges. | ||
The copper is prepared for enamelling, by thorough cleaning (pickle bath, washing, pumice powder, washing etc...), removing the grease and dirt. It is then placed on a mica (silicate material) or titanium (high temperature metal) backing sheet. Enamel cannot stick to these materials. The enamel is mixed with water or a klyr-fire gum solution, into a paste and applied to the holes with a paint brush. Firing of the enamel takes place in a kiln. |
||
The enamelling process is repeated, until the enamel is the same thickness as the copper. A final firing should produce a ‘full fuse’ (smooth finish). |
