Production method of glass compact, production device and glass compact of glass compact

摘要

The case of pressurization formation you hold down temperature variation of the melted glass drop to minimum, you designate that the production device of the glass compact which is used for the production method, and this production method of the glass compact which can produce the glass compact of the quality which is stabilized efficiently is offered as purpose. Directing to the under mold, it supplies the melted glass drop to the under mold by falling the melted glass drop from upward. To inspect the fact that the melted glass drop which fell arrives in specified position, after inspecting, when predetermined time elapsing, it starts the pressurization of the melted glass drop with the formation die.
