Terra Firma offers a palette of 75 glaze colors; most characterized by a complex mottling unique to handmade tile. All tile are made to order where any tile, whether flat field or decorative relief or moulding, may be glazed in any of the available glaze colors. We have recently expanded our selection of glazes, so most of the newer ones are still not very well represented on decorative relief tiles in the catalogue portion of the website, but they are still very much available for use on them. To get an idea as to how these newer glazes will appear on decorative relief, please see the detail view on the Color Chart page.

Throughout the website, there are pictured many decorative relief tiles with multiple colors applied (Glaze Color Group C). We have done extensive testing of various combinations and those represented have proven to be some of the most successful. If you see a combination that appeals to you on any one deco, it can also be used on any of the decorative relief tile we offer even though it may not be specifically pictured. If you are ever interested in a possible combination that you do not see, we would be glad to advise whether it would be feasible. In other words, we are very flexible.

Please notice that all tile are modular. The actual size is 3/16” smaller than the nominal size. This allows the tile to be combined in any configuration using a 3/16” grout joint. Since all tile are made by hand, there will be slight variations in size and shape, giving the tile an organic quality unique to handmade tile.

Shown on the Design Ideas page are several arrangements of tile in configurations that would be appropriate for centerpieces on a backsplash or fireplace. They can be adapted to different designs by simply substituting decorative relief tile of the same size shown or adding more or less field tile. For use in a backsplash, these centerpieces can be easily set into surrounding field tile of your choice. We will be happy to make suggestions that could be helpful in adapting Terra Firma tile to your project.

The primary ambition of Terra Firma is to create tile that is both beautiful and functional. In order to achieve this goal, handmade tile should reflect the aesthetics and skill of the artisan who produces it. The typical handmade process lends itself very well to this personal interpretation with no two tile being exactly alike. Our original designs are carved, then made into plaster molds. Wet clay is pressed into these plaster molds, turned out and dried. After drying, the raw tile are bisque fired in preparation for glazing. Glaze is then applied by hand and the finished tile fired in a glaze kiln.

Besides the design, there are two important factors that contribute to the distinctiveness and personality of handmade tile:
FORMING:
Unlike machine made tile, the handmade tile process uses wet clay during the forming stage. Because the clay is wet, the tile shrinks considerably during the drying and firing. The water content of the clay when it is pressed will affect the amount of shrinkage. Thus, as the water content varies, so does the final size. Handmade tile are also handled quite a bit while being formed. The tile will take on signs of this handling, especially when the clay is malleable. Both shrinkage and handling combine in the final tile installation to create very subtle variations with an organic vibrancy and life of its own.

GLAZING:
Glaze application and chemistry are also very important. We prefer brush application as it gives a large degree of control to the skilled artisan who must master the idiosyncrasies of each tile design and glaze color in order to achieve the desired results. Thus shrinkage, handling, glaze application and firing all contribute to the natural, desirable imperfections that help give handmade tile its richness and beauty.
