dc.description.abstract	Green and fired properties of three electrical porcelain bodies were compared. The three bodies were not significantly different, except for their plasticity. One of the bodies required a higher water content to develop similar plastic characteristics (27 %d.w.b. compared to 21 and 22%d.w.b.). To modify the plasticity of this body, changes in the particle size distribution of the coarse particles and modifications in particleparticle interactions were evaluated. Plasticity was not affected by changes in particle size distribution of the coarse particles made by replacement of coarser feldspars for the regular feldspar. Particle-particle interactions, in turn, showed a significant effect on the plasticity of the body. Plasticity was manipulated by dispersant and coagulant additions. Reductions in the water content required for extrusion from 27 %d.w.b. to as low as 20.4 %d.w.b were achieved by the addition of dispersant.	en_US
