Marble Mosaic Portrait in progress using Hammer & Hardie.

Close up cutting marble with hammer & hardie.

Mosaic Art Source mosaic definitions:

hammer – italian “martellina” – mosaic tool used with a hardie to cut tesserae since ancient times.

hardie – used with a hammer the hardie has a chiseled edge and is traditionally mounted in a log.

cutting tesserae
cutting – the method used to break up materials into various sizes of tesserae. The hammer and hardie have been used since ancient times and are still one of the preferred methods for smalti & stone. The smalti or stone is placed on the blade of the chisel at right angles and by delivering a sharp blow with the hammer a clean-cut is made. To facilitate cutting glass, the surface may be scored beforehand with a diamond tool. With smalti, since the cut edge reflects more of its brilliance, it is usually placed facing outwards in the mosaic (except in the case of metal-leaf tesserae). Modern tools for cutting include tile nippers, tile cutters, wet saws & glass cutters.

Glueing marble tesserae directly to base creating mosaic portrait, notice the andemento sketched in to establish flow.

Mosaic Art Source mosaic definition:

direct method – the design is sketched onto a base and the tesserae are adhered directly onto it. When complete, a layer of grout can be spread over the tiles then wiped off, filling any spaces between the tiles. The only drawback to this method is that repositioning tiles is difficult after the adhesive has set. (usually involves a chisel)

Mosaic Art Source mosaic definitions:

andamento – mosaic detail
andamento – movement or flow of tesserae, often accentuated by the interstices.

base – (or substrate) – the surface that the tesserae are adhered to. ex. wood, metal, glass.

cartoon for mosaic reproduction

cartoon – a full size drawing of the mosaic which can include color and andemento. When creating a reproduction each tesserae is drawn in after taking an exact tracing from the original.

Smalti address in progress – indirect technique.

Mosaic Art Source mosaic definitions:

tesserae face down image after flipping

indirect method – adhere tesserae face down on a temporary surface (craft paper) with a temporary glue. When complete apply mortar to the mosaic (back buttering) then flip it onto the final surface, also prepared with mortar. Press the mosaic firmly into the adhesive to get a firm bond, level and when set, remove paper with water. Corrections are easier to make using this method but there are a few drawbacks; the tiles may shift in the process and you must be able to envision the mirror image of the design. You work looking at the back of the tiles, (which are not always the same as the front) therefore you don’t really see the upside of the mosaic until you flip it. Very difficult especially for figures as in the example above of Lilian Broca’s “Queen Esther”. copyright © 2006 Lilian Broca

mosaic-smalti  smalti

smalto (pl. smalti) – smalti is characterized by its dazzling range of brilliant opaque colors. Smalti is prepared by adding crystalline material (corpo) and coloured material (anima) to the colourless or coloured fused glass. Smalti is literally available in thousands of colors, is a very stable glass, easy to cut and very durable.
