Abstract
Abstract A surgeon's glove having a surface adapted to fit against the surgeon's hand. A coating of a water-soluble innocuous powder, such as sodium bicarbonate, having a particle size in the range of 2 to 30 microns. The powder is applied to a rubber surgeon's glove during a heat cure cycle while the glove is at a temperature in the range of 170° F. to 210° F., and the glove is sufficiently tacky to stick to a substantial portion of the powder, but not sufficiently wet to dissolve the powder.
