Abstract
PURPOSE: To obtain the titled vessel with superior abrasion resistance and internal pressure resistance by adding a thickener to a soln. of an alkali salt necessary for ion exchange, applying the thickener-added soln. to a glass vessel while making the amount to the outer surface larger than the amount to the inner surface, and heat- treating the vessel.
CONSTITUTION: A thickener such as starch, gelatin, natural gum, methylcellulose or polyvinyl alcohol is added to an aqueous soln. or a suspension of an alkali salt such as KNO3 or KCl necessary for ion exchange in such an amount that the viscosity is adjusted preferably to 10W2,000cps, preparing a pastelike fluid. This fluid is applied to a glass vessel by spraying or other method while making the amount to the outer surface larger than the amount to the inner surface, and the vessel is heated to about 400W530°C for about 5W60min to perform heat treatment necessary for ion exchange. Thus, the desired tempered glass vessel is manufactured efficiently.
