ABSTRACT:
A wax-like substance mainly consisting of a saturated chain hydrocarbon, in which a weight ratio (C/H) of carbon and hydrogen is 5.839-6.018, a total weight % of the carbon and the hydrogen is 98.5%-100%, a number-average molecular weight (Mn) is 3.0.times.10.sup.3 -1.0.times.10.sup.4, a weight-average molecular weight (Mw) is 1.0.times.10.sup.4 -5.0.times.10.sup.4 and Mw/Mn is 1.0-5.0. In the case of using it for carving and casting, for example, wax-like substance can be repeatedly used, and has the excellent workability. Moreover, the wax-like substance provides easy dewaxing from a mold material. In other words, it provides convenient use. In addition, after a master model is made by processing the wax-like substance and covered with a mold material, it is dewaxed. Molten metal is poured into the mold material, and a shaped article is produced by cooling and solidifying the mold material where the molten metal has been poured. As a result, shaped articles, such as a decoration having a very fine pattern, an accessory having a complicated and three-dimensional configuration, or an industrial art object can be suitably produced.
