Antique Czech chandelier connector prism hand press molding pliers tool

Antique vintage Czech Bohemian original rectangle glass chandelier connector prism hand press molding pliers. Dating from the early part of the last century this is a traditional tool, used in the times prior to full mechanisation. The actual making of the glass at this time, on the whole, remained a cottage industry, in that the pliers and attached molds were bought and used by individuals or families who would work from home to supply the companies that would trade the finished items. Each house would have a furnace in which glass rods were heated before the glass items were individually pressed before being polished by hand.
These are made for pressing a rectangle connector chandelier prism. Stamped with "JPH", the workers initials. These are still in working condition, having been used in the latter part of the last century. The surface metal does have some pitting which is to be expected and years of untouched patina.
A nice collectible part of Czech Bohemian glass making history.
