Cool Tools - EZ925® Sterling Silver Clay - 25 gram

Ready to use directly from the package, EZ925 is a metal clay that offers the sintered strength of a sterling silver, making it an excellent candidate for making delicate or complex pieces. With a high moisture content and long working time, this clay forms and manipulates without drying or cracking. This clay is soft and smooth, and rolls, forms molds, coils and joins smoothly with ease. For best long term storage and to maintain hydration and workability, store unused EZ925 in a clay hydrator charged with distilled water. In instances where the clay becomes over-worked or dry, fold distilled water into the clay until correct, re-moistened consistency is achieved. Adding Rejuvenate to EZ925 will result in a hardening effect on this clay body. Rejuvenate should not be used with this clay. Greenware EZ925 readily absorbs liquid, you may even notice added water immediately being pulled into the dried clay. For this reason, paste, syringe, or a thick hand made slip is recommended for making connections when combining greenware to greenware or greenware to lump/ wet clay. In its dried, greenware stage, EZ925 is easy to sand and sands very smoothly and quickly. Dried pieces are quite flexible, which is helpful when assembling or manipulating greenware. EZ925 drills easily in its greenware state, and is not prone to cracking or chipping. Glycerin can be added to increase flexibility in the greenware phase without adversely affecting the clay. EZ925 is however already moderately flexible in the greenware phase, so adding glycerin is likely not necessary unless you’re planning lots of sharp and drastic greenware bends. This clay requires a kiln. It cannot be torch fired. EZ925 is an open shelf sterling, meaning that it does not need to be embedded in carbon while firing in order to successfully sinter. After ensuring the clay is bone-dry, there are many kiln firing support options available for firing EZ925. EZ925 pieces with a flat back can be fired on a hard ceramic kiln shelf, or a ceramic fiber kiln shelf raised up from the kiln floor (place the firing board of your choice on kiln posts to raise it up off of the kiln floor). EZ925 pieces that have dimension or need additional support can be fired in alumina hydrate or crushed fine vermiculite in a fused silica dish, or can be placed on supported superwool fiber blanket (place your fused silica dish or kiln shelf under the superwool fiber blanket on kiln posts to raise them up off the kiln floor). For most pieces, like pendants, earrings, already formed bracelets, and pieces that won’t be bent- Fire at full ramp speed to 1550°F/ 843°C for 1 hour. If bending post firing, we recommend adding an additional one to two hours hold at 1550°F/ 843°C as not all kilns are accurately calibrated. An additional one or two hours of “soak” time ensures complete sintering. If you are creating large pieces 10 cards or thicker, we recommend adding a burnout phase in order to assure all binder is able to burn out before the temperature climbs up to sintering temperature. To fire thick pieces, especially those that may be bent, place the bone dry greenware on any firing support of your choice (from the list above- no need to place the clay on wire mesh and transfer it) and fire at full ramp to 650°F/ 343°C and hold for 30 minutes. Then full ramp up to 1550°F/ 843°C for 1-2 hours.
