<p>PROBLEM TO BE SOLVED: To in cinerate organic matter without being remainea in burning and keep an operating feeling from being impaired by containing an ester compound having a specified value of boiling point in a malaxation liquid in a specified ratio. SOLUTION: An ester compound having a boiling point of 100 deg.C to 250 deg.C is contained by 5 wt.% or more to form a malaxation liquid for dental porcelain material. A mixture composed of an ester compound having a boiling point of 100 deg.C to 250 deg.C by 10-90 wt.% and 10 to 90 wt.% of a polyhydric alcohol having 3-8C is used as main component to form a malaxation liquid for dental porcelain. When this malaxation liquid is used to a graze, stain recently developed and burnt at low temperature, after burning, the organic matter will not remain nor colored. Matching with powder is good so that kneading operation is easy, besides powder is kept from being dried during grinding so as to facilitate the color tone control.</p> |
