Styles & Sizes
We make a wide variety of bisque sinks styles and sizes ready for your custom glazing and decoration. These include Rimmed Sinks for counter top mounting, Vessel Sinks for counter surface mounting and Under Mount Sinks for under counter mounting.
For four decades Maine Kiln Works has been producing hand formed bath sinks and basins of the very highest quality. Each unit in his Water Stone Sink line has been carefully designed and fully tested to guarantee your complete satisfaction.
Using a range of specialized tools as well as traditional processes we custom form every sink. Our Bisque Sinks are fired to cone ▲06 to provide a stable but absorbent base for decorative application and finish glazing. Forty years of continuous production demonstrates an uncompromising commitment to a unique product in support of discriminating decorative artists.
What clay body do you use for your sinks?
We offer sinks made of cone ▲10 Porcelain and Stoneware.
What firing temperature do you recommend?
Our Porcelain and Stoneware may be glaze fired from 2232℉ (cone ▲6) to 2345℉ (cone ▲10). Though absorbency is slightly higher at lower temperature—our clays are vitreous across this temperature range.
What fired porosity or absorption should I expect?
As a relative indicator of porosity—cone ▲6 absorption will be approximately 1% and cone ▲10 absorption near 0%.
Should your sinks be fired in electric kilns or fuel burning kilns?
Our sinks can be glaze fired in oxidation or reduction in either electric kilns or fuel burning gas kilns.
What finish glaze firing schedule should I use?
3 firing segments are suggested. The first at a rate of 150℉ until 250℉ is reached. The second at a rate of 400℉ until 2095℉ is reached. The third and final segment at a rate of 120℉ until the desired temperature 2232℉ (cone ▲6) to 2345℉ (cone ▲10) is reached. Following this schedule to cone ▲10 will take approximately 8 hours depending on kiln stacking density and kiln watt rating.
Will my glaze craze on your sinks?
Our sink clays are designed with an average coefficient of expansion to fit typical glaze formulas without crazing or dunting. You may however experience crazing or dunting if your glaze has an abnormally high or low expansion. We always recommend the use of our included glaze test tiles prior to glaze firing your sink.
Will your sinks warp or deform during glaze firing?
Our sinks are press formed at 60 tons per square inch to produce an exceptionally dense and stable product that consistently resists warping or deformation during glaze firing. Uneven heat distribution due to kiln design or stacking pattern can increase warping potential.
How can I be sure my glazes will work on your sinks.
All or our sinks are shipped with glaze test tiles so you can proof test your glazes prior to glaze firing your sink.
