We have two types of seals to mark the glass:

Stamps for engraving medallions of molten glass:

Round bronze seal engraved in low relief to make embossed glass medallions from a molten glass ball. The seal for marking hot glass is thick (15mm) so that it retains the temperature for longer and obtains excellent durability.

They also serve to make pendants or glass jewelry.

Seals for marking pieces of hot glass:

Directly on the glass piece is pressed with the seal to mark glass engraved in relief, in this way the piece remains with the mark in low relief.

These seals can be mirrored, to mark the pieces of hot glass so that they can be seen on the marked side, or they can be made on the right, to mark backwards and then be seen on the other side of the glass. For example to mark glass asses on their outer face and that the logo is seen from inside the glass.
