PPT-B.Ball clay Ball clays are remarkable because of their high plasticity when mixed with

011 μm which is stabilized by a considerable content of the organic matter up to 2 wt Because of fine particles size the water demand for ball clays is higher than for most china clays The fine particle size also gives the ball clay bodies higher green strength and higher fired strength than other clays In the raw state ball clays range in color from light brown to nearly black depending on the organic content Ball clays .

An electronic balance is connected to a PC in order to record the time dependence of the measured weight. A light frame is mounted on a tall beaker filled with water. The frame has a holder allowing controlled release of a small ball such that it falls into the water. The beaker is placed on the balance as depicted in the Figure. Investigate how the readings of the balance reflect the different phases of the motion of the ball.. Topics. Basic Rules. Throwing Mechanics. Catching. Hitting. Positional Play. Practice Plan.
