Lead poisoning from pottery glaze and paint NO form of lead or arsenic may be used in our materials without specific clearance and training from the instructor. Lead is hazardous to breathe, to ingest (eat), and can be released from firing into the air. Finally, any container glazed with these materials may be toxic to eat or drink from because lead can leach into food or drink stored in the vessel. While new pottery sold today in the United States is generally assumed to be safe from lead, occasionally one still reads about cases of pottery that is accidentally sold with dangerous amounts of lead in the glaze. In paint, lead carbonate was formerly used for white. The following hazardous materials may be used with care and precautions. Antimony oxide, barium of any form, beryllium, borax, cadmium, selenium, cobalt, colemanite (or gerstley borate), copper, chromium (chrome), lustre preparations, manganese, nickel, potassium dichromate, vanadium, and zinc.

Throw, Cut, and Paste: Combining Wheel Throwing, Handbuilding and Multi-Step Glazing to Create Distinctive Vibrant Forms : Ceramic Arts DailyThe Pedestal Gravity is one of the challenges faced when it comes to thrown forms. A thrown and altered shape may have a dynamic profile from the waist up while the foot often remains static and gravity bound. fig. 1 (click to enlarge) Starting a piece by throwing it up-side down allows alteration to the foot and the opportunity to create a dynamic negative shape under the base. fig. 2 To begin the pedestal, throw a tapered cylinder with a ¼-inch thick floor. fig. 3 After this rim has dried slightly but is still soft and pliable, you’re ready to alter the shape. fig. 4 Cut into the rim on either side of your mark using an X-Acto knife, making an arced, V shape. fig. 5 Following your design ideas and sketches for the finished piece, complete any slip-based surface decoration. The Vase fig. 6 The vase is thrown in two parts. fig. 7 After the parts have set up slightly, yet are still pliable, shape the shoulder of the vase into four lobes by stretching out the wall using a damp sponge (figure 6).
Flat to Functional: Handbuilding & Slip Decorating : Ceramic Arts DailyIn this installment of the Ceramic Arts Daily Presents Video Series, potter Lisa Naples shares her love of handbuilding with earthenware. Determined to change the myth that earthenware is punky and weak, Lisa explains how this beautiful forgiving clay body is every bit as strong as its higher-fired counterparts when it’s fired beyond the traditional Cone 04. In addition to covering the mechanics of good slab rolling, Lisa guides you through her straightforward soft-slab building techniques. She demonstrates how to add interest to handbuilt forms by adding texture and cutting darts to create custom shapes. In the decorating portion of the video, Lisa gives a thorough explanation of her “dry” and “wet” slip brushing techniques, explaining how they can add both beautiful texture and color.

Cone 6 glaze recipes | Great mid range pottery glazes | OxidationThe benefits of firing underglazed pottery (mainly children's work) is that the end result is much more durable than low fired projects. We really wanted the projects to last for generations remembering how our parents and grandparents cherished our school ceramic work. We therefore, fire all of our work and our students work to cone 6 including underglazes. We learned that the majority of underglazes do not yield good and expected results and not all clear glazes interact favorably with underglazes. See children's underglazed cone 6 projects.
Longquan celadonTruncated with mountings Longquan Celadon in the Topkapı Palace, Istanbul, Turkey. Longquan celadon (龍泉青磁) refers to Chinese celadon produced in Longquan (龍泉) kilns which were largely located in Lishui prefecture in southwestern Zhejiang Province. With those in other prefectures the total of discovered kiln sites is over two hundred, making the Longquan celadon production area one of the largest historical ceramic centers in all of China. Overview A Longquan Ware Celadon Vase, Song Dynasty, 13th Century, from the Nantoyōsō Collection, Japan Celadon production had a long history at Longquan and related sites, but it was not until the Five Dynasties (五代 907–960) and Northern Song (北宋 960–1127) period that production of scale truly began. Longquan celadons thus were an important part of China's export economy for over five-hundred years. Southern Song celadons display the greatest variety of shape and glaze color.
