Mold Blown Roman Cobalt Amphora Late 1st Century AD
The side view of this amphora clearly shows a mold line running down the piece where the two mold halves were joined when the glass was blown into the mold.
The most famous glass maker to employ the mold blowing technique is Ennion of the Sidonian school, which he founded in the first half of the 1st Century AD.
His signature has been preserved on more than 30 mold-blown vessels discovered in archeological digs.
The precision of his molds are legendary in that they were designed to allow a quick release without distorting the vessel or removing too much heat from the glass.
This retention of heat enabled the glass maker to quickly add handles to his highly detailed designs.
