A bstract A number of organic binders were added to a talc‐water system and the mixtures were extruded at low pressures through a deairing extruder. These binders were (1) flours, starches (both short and long chain), (2) gums, (3) alcohols and cellulose derivatives, (4) wood extracts, and (5) alginates. Data are presented on wet strength, water retention during extrusion, extrusion characteristics, drying shrinkage, water of plasticity, days required to air dry, warpage, dry modulus of rupture, hardness, and migration.
