The present invention provides an interlayer for a laminated glass which does not give rise to the moiré phenomenon even when the arrangement and pitch of its embossments are orderly, hence providing for good workability in cutting and laminating operations and good deaeration in preliminary contact bonding, thus insuring the production of a laminated glass of high quality with a minimum of rejects for reasons of air bubbles, and a laminated glass containing said interlayer. The invention also provides an interlayer for a laminated glass which provides for good deaeration without a risk for premature marginal sealing even if the temperature at initiation of deaeration at preliminary contact bonding is not critically controlled and which does not require raising of temperature for achieving a marginal seal of the glass-interlayer assembly, and a laminated glass containing said interlayer.

An apparatus and method are disclosed in which ultrasonic vibration is used to assist the degassing of molten metals or metal alloys thereby reducing gas content in the molten metals or alloys. High-intensity ultrasonic vibration is applied to a radiator that creates cavitation bubbles, induces acoustic streaming in the melt, and breaks up purge gas (e.g., argon or nitrogen) which is intentionally introduced in a small amount into the melt in order to collect the cavitation bubbles and to make the cavitation bubbles survive in the melt. The molten metal or alloy in one version of the invention is an aluminum alloy. The ultrasonic vibrations create cavitation bubbles and break up the large purge gas bubbles into small bubbles and disperse the bubbles in the molten metal or alloy more uniformly, resulting in a fast and clean degassing.
