Eternal Love

How-to

Color Engraving - NO Paint!! Works on ceramic tiles and glass. Different color ceramic glazes can be used. Sax Cranberry Red yields a light brownish red, Sax Old Navy yields a light blue, copper oxide yields a metallic copper, and cobalt oxide yields a rich, dark blue that is great for glass bottles - MUCH more pleasing to the eye than the black obtained with TiO2. The LP file attached is only for the Eternal Love tile, but the picture shows a cat with navy blue glaze and a cat cranberry red glaze (I like cats, and made a lot of cat boxes), and a bottle labeled with cobalt oxide. My wife had me label just about every glass bottle in the house. I haven't tried other glazes or oxides, yet. Glazes require very low power and a VERY thin coat, whereas the oxides require about 50% power and a thicker coat (usually two coats). Glazes result in a pastel color, whereas the oxides are bright and vivid. I have only tried one other oxide - chromium oxide - which results in a metallic silver-white. Some oxides and compounds, particularly those containing cadmium, are extremely toxic and should not be used.

How-to Tutorial

Step 1 Set-up fixture for engraving the tile

Clean the tile with alcohol. Use two of the L shaped brackets to hold the ceramic tile firmly in place, but arranged so that the tile can be removed and replaced in EXACTLY the same location.

Step 2 Engrave Stem

Open TRI COLOR ROSE in Design Space.

Hide all but the stem, and pre-view.

Mark the outline of the preview with a felt tip pen.

Remove the tile, coat the area inside the outline with two coats of TiO2, applied with a soft brush and let dry.

Replace the tile in the fixture. Set the engraving parameters to 50% power, depth 88, and engrave the stem (black)

Remove the tile, and wash off the excess TiO2
