It co u ld be argued that there are two types of plasticity : good and bad . If a material works within a specific process, the plasticity is perceived as good. If the mater ial does no t fun cti on . or creates defects in the produc t during the forming process. the pla sticity must be bad .

  • Earthenware Clays
    Arbuckle Earthenware Earthenware Clays Earthenware usually means a porous clay body maturing between cone 06 – cone 01 (1873°F ‐ 2152°F). Absorption varies generally between 5% ‐20%. Earthenware clay is usually not fired to vitrification (a hard, dense, glassy, non‐absorbent state ‐ cf. porcelain). This means pieces with crazed glaze may seep liquids. Terra sigillata applied to the foot helps decrease absorption and reduce delayed crazing. Low fire fluxes melt over a shorter range than high fire materials, and firing an earthenware body to near vitrification usually results in a dense, brittle body with poor thermal shock resistance and increased warping and dunting potential. Although it is possible to fire terra cotta in a gas kiln in oxidation, this is often difficult to control. Reduced areas may be less absorbent than the rest of the body and cause problems in glazing. Most lowfire ware is fired in electric kilns. Gail Kendall, Tureen, handbuilt Raku firing and bodies are special cases. A less dense body has better thermal shock resistance and will insulate better. Earthenware generally shrinks less than stoneware and porcelain, and as a result is often used for sculpture. See Etruscan full‐size figure sculpture and sarcophagi in terra cotta. At low temperatures, glaze may look superficial & generally lacks the depth and richness of high fire glazes. The trade‐offs are: • a brighter palette and an extended range of color. Many commercial stains burn out before cone 10 or are fugitive in reduction. • accessible technology. Small electric test kilns may be able to plug into ordinary 115 volt outlets, bigger kilns usually require 208 or 220 volt service (the type required by many air conditioners and electric dryers).

  • American and English Ball Clays
    AMERICAN AND ENGLISH BALL CLAYS. By H. H. Sortwell. ABSTRACT. The six American and fifteen English clays in use in the largest quantities were studied. No great differences were noted in water of plasticity, all of the clays falling within a range of a few per cent. The Dorset clays showed a slightly higher drying shrinkage than the other clays tested. The transverse strength of the Tennessee clays when mixed with an equal weight of flint averaged 366 pounds per square inch, the Kentucky clays 282, the Dorset clays 405, the Devon clays 443, and English clays, whose source was not known, 419. The American clays contained less mineral and carbonaceous matter which would be retained by 120 mesh. The rate of flow of slips through the efflux viscosimeter did not appear to be a valuable criterion in differentiating between ball clays. The Kentucky clays were almost free from carbonaceous material requiring oxida- tion, the Tennessee and Dorset clays contained a small amount, while the Devon clays were highly carbonaceous and difficult to oxidize. The American clays showed a gradual reduction in porosity, and the volume was constantly changing from cone 01 to cone 12. Only one domestic clay was vitrified by cone 8. The English clays vitrified at a low temperature and remained almost constant in porosity and volume up to cone 12. No evidence of overfiring was observed. In a standard body the Tennessee clays as a class gave the best color, the Kentucky and Devon clays were next, and the Dorset clays were comparatively poor in coloring effect.
