摘要:
A process for removing blisters (large bubbles in a glassmelt) and seeds (small bubbles in a glassmelt) from a glassmelt by feeding helium bubbles (6) having a diameter between about 0.5 centimeter and about 3 centimeters at a prescribed flow rate and location to effectively produce a substantially bubble-free article.
