I create my mosaic pieces from either an earthenware clay or from mid-fire sculpture clay. I begin by making the individual elements of the mosaic (the tessera) from a slab of clay by cutting shapes, adding all layers, textures, and details for the piece as the original idea evolves. When the pieces are dry (usually 5-7 days) they are fired in my studio kiln to bisque (1855 degrees Fahrenheit). When cool, I hand paint each piece with several colors and layers of glaze. The pieces are then fired again to over 2200 degrees Fahrenheit for mid-fire clays and over 1800 degrees for earthenware. Once all the tessera are created, I begin the mosaic by attaching each piece with thinset (cement) to a base of Wedi board. Wedi board is a waterproof lightweight alternative to wood. Once all pieces are glued and dried, 2-4 days, I grout each piece. The back has the wire for hanging already attached before the mosaic is create, and is signed and dated. Because I do not use molds in my work, each mosaic is a unique, completely handmade, one of a kind piece of art! All items can be made to order and will be a version, not an exact replica, of the example shown in the listing. Although my mosaics are created with weather safe elements, I would recommend hanging them in a location protected from direct weather and would bring the piece inside during the colder winter months.
