Hazards in Ceramic

Hazards in Ceramic
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.

Chart: Health & Safety in the Arts: Ceramics The Leach Pottery 1curric Eye Protection Studio Safety Eye Protection in the Pottery Studio by Jeff Zamek When working in the ceramics studio, there are situations where eye protection is needed. While working with ceramic materials is not an inherently dangerous endeavor, using the proper safety equipment can help the potter easily avoid a few potentially hazardous situations. Fortunately, eye protection developed for use in several major manufacturing areas such as foundries, steel mills, glass production, metal fabrication and casting industries, is readily available to the studio potter. Infrared/Ultraviolet Hazards In the past, glassblowers were subjected to infrared and ultraviolet light when looking into high-temperature molten glass tanks. Infrared and ultraviolet radiation are part of the electromagnetic spectrum with visible light being just one segment of the entire range. The cobalt-blue #5 lens is rated on a different scale and does not correspond to the green-shaded welding glasses #5. Resources

Home | WikiClay Building A Hollow Bust Rolled slabs insure an even thickness throughout the piece, except, of course when additions are made. It depends on the size of the piece. A life size bust may have added hollow forms (could be the nose) like a massive amount of hair. There is less chance of air bubbles as when you are working with just wads of clay. Equus Machina by George Palovich Tang Dynasty Horse Geo Silicosis - Potter's Rot Silicosis (particularly the acute form) is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin). It may often be misdiagnosed as pulmonary edema (fluid in the lungs), pneumonia, or tuberculosis. The name silicosis (from the Latin silex, or flint) was originally used in 1870 by Achille Visconti (1836-1911), prosector in the Ospedale Maggiore of Milan.[3] The recognition of respiratory problems from breathing in dust dates to ancient Greeks and Romans.[4] Agricola, in the mid-16th century, wrote about lung problems from dust inhalation in miners. Classification[edit] Classification of silicosis is made according to the disease's severity (including radiographic pattern), onset, and rapidity of progression.[6] These include: Chronic simple silicosis Usually resulting from long-term exposure (10 years or more) to relatively low concentrations of silica dust and usually appearing 10–30 years after first exposure.[7] This is the most common type of silicosis.

50 Inspiring Pottery Blogs One of the world’s oldest forms of art, pottery has been around since the days of the cave man. Used for eating, serving, or just admiring, pottery has loads of purposes. However, with the Wal-Mart age, so many of us just go to the store to get our pots and clay. But for those who can’t live on pre-manufactured clay alone, that isn’t enough.

Dukno Yoon / MetalWorks Movement and interactive relationship with the body has been the most important element throughout my body of work. However through these works, I also started to explore the mechanical structure as a form. Mechanical structure becomes the most enjoyable form to me as it becomes complex yet remains simple and coherent. The contrast between metal structural form and natural feather, together with the repetitive and whimsical movements of fragile wings, provokes the imagination and evolves the intimate relationship between work and viewer/wearer. Although the recent series, segmented wings have been focused on the formal challenge to engineer an intricate movement that simulates bird wings, these works are intended to be a series of poems in which I develope my own formal language, interpret the nature of wings, create various structural forms with movements, and share the metaphor, imagination, humor, with viewer/wearer.

Respirators for Potters Ceramic Studio Safety Respirators for Potters by Jeff Zamek When sweeping the studio, every potter at some point wonders, “What should I do to protect myself from the clay dust?” Imagine what’s floating around in your studio when walking or sweeping up at the end of the day. On days when direct sunlight enters the studio, it’s possible to see raw materials and clay dust in the air; but it’s the stuff you can’t see that’s the problem. Clay is a very small hexagonal-plate-shaped particle material and can range from 100 microns (µ) to 0.1µ in size depending on the specific type of clay. A safe and conservative approach goes a long way in protecting yourself from airborne particles-both visible and invisible. Respirator Filters Every respirator has some type of filter to trap particles. For many years, HEPA filters have been the standard for the industry. If It Fits ... When purchasing any respirator, look for the new NIOSH codes. Click here to leave a comment
