» Slip, Engobe, or Underglaze? Robin Hopper Demystifies Three Common Pottery Materials Slips and Engobes Slips are predominantly liquefied clay; they usually are applied on wet to dry greenware. Engobes usually have a lower clay content and also can be used on bisque-fired ware. The word slip generally is used to describe any clay in liquid form. All slips and engobes can be colored with oxides, carbonates and stains. Casting slips give extremely good properties for use as a drawing medium in a fine-to-medium aperture trailer. Slips used for decorating usually are mixed with water only, unless specific qualities of fluidity or viscosity are desired. Slips can be used to coat another clay to make it lighter, darker or colored. 7 Methods of Slip Decoration Engobes and Underglazes The word engobe is used most often in North America and describes a wider range of uses in the development of the decorative surface. Materials for making engobes fall into six groups: 1) Clays, with kaolin or calcined kaolin usually used in place of ball clay to counteract shrinkage 6) Colorants.
Paper Mache Clay Recipe Several years ago I developed a new recipe for a sculptural material I call “paper mache clay.” This material is so easy to use and so easy to make that I now use it exclusively for all my paper mache sculptures. The recipe has now gone “viral” and is being used by artists all over the world. It might be a bit more accurate to call this material “home-made air-dried cellulose-reinforced polymer clay,” but that’s way too hard to say (or type!), so for now, let’s just call it paper mache clay. The first video below shows how to make the paper mache clay, and the second video answers some common questions that I’ve received from readers since I first developed this recipe. I usually make mine fairly thin so it can be spread over an armature like frosting, by using less flour than the recipe calls for – but you can also make it thicker, with more flour, when you want more control over the modeling process.

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.

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. Lead has many very serious effects if ingested. Lead can be absorbed from glazes by acidic food or drink. In paint, lead carbonate was formerly used for white. The following hazardous materials may be used with care and precautions. The court did not find legal proof of negligence on the part of the chemical suppliers. See:Alfred Franzblau, et.al. OUCH!

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. In firing a piece with a considerable wad of paper inside, sometimes there is just too much smoke and burn residue for an electric kiln. Constant exposure to live burning of combustibles in an electric kiln is hard on the coils and they deteriorate faster. Equus Machina by George Palovich Tang Dynasty Horse Geo
