A device for dispensing ingredients, such as the ingredients for a dental amalgam, has a handle portion and a head portion formed of mating parts with the handle angulated to the head and formed for convenient gripping by the user's hand. A slide mounted in the head slides laterally when pushed by the user's thumb to transport measured ingredients to a common aperture for delivery into a container. The container, when put in place, releases a latch that holds the slide normally in measuring position and prevents transport of the ingredients unless the container is in position to catch them. Adjustment of a measuring chamber for liquid mercury, to accurately proportion it, is by a valve having an end projecting, more or less, into a chamber, so as to vary the volume of the chamber. The position of the valve is controlled by a rectilinearly movable cam whose position may be fixed by a lock nut which normally is inaccessible in a recess in the head portion.

An improved dental composition comprises an admixture in specified proportions of two powdered alloys of specified composition, one in the form of spheres, the other in the form of irregularly-shaped particles such as flakes. When the admixture is amalgamated with mercury, a corrosion-resistant dental amalgam having enhanced mechanical properties and handling characteristics is produced.

A novel dental composition comprises an admixture of two forms of a powdered alloy in specified proportions, i. e. , a major proportion in the form of relatively smooth spheroidal particles, e. g. , spheres, and a minor proportion in the form of relatively rough, irregularly shaped particles, e. g. , flakes. The resulting dental composition requires less mercury for amalgamation and exhibits enhanced physical properties and handling characteristics.

An improved dental composition comprises a uniform admixture in specified proportions of two powdered alloys of specified structure and composition, which when amalgamated with mercury produces a corrosion-resistant dental amalgam having enhanced mechanical properties and handling characteristics.
