Abstract: A deaerated talc may include micronized, talc powder having a Hegman rating of 4.0 or greater. A deaerated talc may include micronized talc powder having enough cohesive strength for form agglomerations measuring 100 millimeters or less, 75 millimeters or less, or 50 millimeters or less. A deaerated talc product may include a micronized talc powder, and a bag containing the deaerated talc. The micronized talc powder may be deaerated via application of force to the micronized talc powder in at least two directions, including a first direction substantially parallel to the longitudinal direction of the bag and a second direction.
