DARK STAR FORMULA UPDATE 2:
AS OF 9/10/2023 DARK STAR HAS A SLIGHTLY ALTERED FORMULA TO ACCOMMODATE A MATERIAL CHANGE. IT IS NOW MORE SUSCEPTIBLE TO BLOATING WHEN IT IS FIRED BEYOND CONE 6 (AS VERIFIED BY AN ORTON WITNESS CONE). DARKSTAR CAN ABSOLUTELY STILL BE FIRED TO A TRUE CONE 6. IF YOU ENCOUNTER BLOATING, WE RECOMMEND ADJUSTING YOUR FIRING SO THAT IT PEAKS ABOUT A HALF CONE COOLER THAN YOU MAY HAVE IN THE PAST. ALTERNATELY, A SLOWER RAMP IN THE FINAL 300*F MAY ALSO HELP TO OFFSET BLOATING. WE APOLOGIZE FOR ANY INCONVENIENCE THIS CAUSES BUT THIS MATERIAL CHANGE WAS OUT OF OUR CONTROL. ALWAYS TEST YOUR MATERIALS BEFORE PUTTING THEM INTO PRODUCTION.
Everyone loves Dark Star! If you like speckles in your clay but are looking for a body that keeps your glazes brighter, check out this new clay body. Based off of our very popular Ice Man clay body, Dark Star is easy to throw and handbuild with and is very forgiving, smooth, and plastic.
WE RECOMMEND SLOW FIRING SPEEDS IN BOTH BISQUE AND GLAZE WHEN USING ANY CLAY BODY THAT CONTAINS MANGANESE SPECKS DUE TO OFF GASSING. This allows the gasses time to escape properly from the ware. If fired past cone 6, you may experience bloating. Please see Orton cone guide below to for an example of a properly mature cone bend. Always use guide cones when firing!
