Abstract: An apparatus and method facilitates the determination of the desired quantity of portions of comestibles to be consumed by the user. The apparatus includes a visual cue indicia device having indicia thereon being configured in the shape of a familiar object of a size similar to the size of a desired portion of a comestible product to be consumed. The user can control the quantities of portions of comestible groups being consumed. In one form of the invention, the apparatus includes a book having a plurality of pages, at least one of the pages having the visual cue indicia device being removable disposed thereon. The visual cue indicia device preferably includes a paper board sheet having its indicia on the front face thereof to facilitate carrying it conveniently with the user so that it can be use discretely for gauging the size of a portion to be consumed.

Abstract: Photocurable ceramic resins having solids loadings in excess of 40 volume percent and a viscosity of less than 3000 mPa.multidot.s are suitable for multi-layer fabrication of green ceramic parts by stereolithography and similar techniques. The green ceramic parts, which may be of traditional ceramic materials, sinterable metals, or combinations thereof, exhibit low shrinkage upon firing or sintering, and may be used for such applications as rapid prototyping, biocompatible ceramic parts, ceramic cores for investment casting, ceramic molds for metal casting, and the like.
