Abstract: Green ceramic mixture for extruding into an extruded green body includes one or more inorganic components selected from the group consisting of ceramic ingredients, inorganic ceramic-forming ingredients, and combinations thereof, at least one mineral oil, and from about 0.01 wt% to about 0.45 wt% of an antioxidant based on a total weight of the inorganic component(s), by super addition. The mineral oil has a kinematic viscosity of ≥ about 1.9 cSt at 100° C. The at least one antioxidant may have a degradation-rate peak temperature that is greater than the degradation-rate peak temperature of the at least one mineral oil. In some embodiments, the at least one mineral oil includes greater than about 20 wt% alkanes with greater than 20 carbons, based on a total weight of the at least one mineral oil. Methods of making an unfired extruded body using the batch mixture are also disclosed.
