  • Patent number: 5931307
    Abstract: Flatware that can be quickly and easily sorted when placed in a liquid solution, the flatware encompasses three classes, spoons, forks and knives. The spoons have a generally uniform buoyancy so as to float at a first level in the liquid solution, the forks have a generally uniform buoyancy so as to float at a second level in the liquid solution, and the knives have a generally uniform buoyancy so as to float at a third level in the liquid solution. The flatware floats at different levels in the liquid solution which provides the separation of the spoons, forks and knives in the liquid solution and enables the retrieval of the separated flatware in a sorted fashion. An additional method of sorting and removing the flatware from the liquid solution includes mixing in a prescribed amount of salt solution to the liquid solution and/or raising the temperature of the liquid solution a predetermined amount.
