Unglazed Ceramic Tiles


    The Dal-Tile Unglazed Ceramic Tiles sold by Dogwood Ceramic Supply in case and pallet quantities are a key product for decorative and hobby ceramic studios as well as industrial applications where a standardized surface is required for a number of abrasion or absorption tests for various consumer products.

     The Unglazed Ceramic Tiles, also known as blank ceramic tiles or unglazed ceramic bisque tiles are technically an earthenware clay that has been bisque fired to maturity and is suitable for decorating with a wide range of underglaze products such as Duncan's Concepts or Spectrum's 400 series Super-Strokes.  Earthenware clays are commonly referred to as "ceramic" or "low-fire" to distinguish the these tiles from unfinished quarry tile or high temperature porcelains or stoneware, hence the basic product description.  It is this earthenware formulation, in combination with the lower temperature to reach maturation, that yields the porous ceramic bisque tile suitable for a wide range of industrial applications as well as allowing easy decorating by ceramic artists of all ages.  For decorative usage, the 6" x 6" Unglazed Ceramic Tile are generally the most popular size as there is greater surface area for standalone decorative projects.  Because the unglazed bisque tiles are manufactured from earthenware clays, the tile should be covered with an appropriate clear glaze over any artwork completed with underglazes in order to provide a continuous vitreous surface when contact with water or food is anticipated.  While decorating the tile with artwork and designs is most common, the unglazed ceramic tile may also be completed with any number of low fire opaque glazes as well a variety of non-fired acrylic products.  Ultimately the ceramic tile, if properly glazed and fired, can be used for backsplashes, murals, countertops, bathroom walls and of course trivets featuring children's or baby's handprints.  It is this wide ranging decorative and usage options (and low product cost) that is the reason the unglazed ceramic tiles are especially popular with school programs trying to accomplish simple art projects with a limited budget.


     Fired to maturity hotter than Cone 04 (approximately 1940°F) the Unglazed Ceramic Tile should have no additional shrinkage with subsequent glaze firings unless the maturation point is exceeded.  The color of the unglazed ceramic tiles will vary batch to batch from creamy off-white to slight buff or mild grey tones.


Unglazed Ceramic Bisque Tile vary in color


     Product color does not affect the suitability for industrial usages though traditional hobby ceramic customers expecting an absolute pure white tile may be disappointed.  Absorption rate is approximate 14%, making the product suitable for any number of modifications to the Union Carbide Tombstone Test as well as being used as a substrate for abrasion tests.  Obviously, all industrial users should purchase sufficient quantities from a single batch of tile to complete their project and minimize any batch to batch variations in the absorption rate from affecting their testing procedures.  Fortunately Dogwood Ceramic Supply purchases the unglazed tile in pallet quantities from a single production run so as to minimize the issue of different production batches:


Pallets of Unglazed Ceramic Bisque Tile arriving at Dogwood Ceramic Supply


     Both the 4x4 and 6x6 unglazed ceramic tiles are temperature stable up to Cone 04 and may be glaze fired in tile racks without requiring additional support.  The exact maximum temperature of the Unglazed Ceramic Tiles is not known and would obviously be dependent upon firing temperature, duration and physical support.  Unknown results in reduction or high stress firing methods.

6x6 Tile Rack   Tile racks sold by Dogwood Ceramic Supply, such as the 6x6 Tile Rack shown to the left,  are preferable over conventional refractory shelves to maximize the number of tile per kiln load while reducing the mass and firing times.

Hint:  Never glaze the backside of the tile if using racks for firing as the tile will stick to the support arms.

Tile Racks are available for 4x4 and 6x6 tile.
