Sometimes walking around the glass studio we see some surprises, here is some antique czech glass stemware belonging to Alex Abajian.
The coils that you see the foot being made with: these demonstrate one of the oldest glassmaking process that were used before glass was even blown; whereby molten glass was wound around a clay core to create vessels..

This process was followed by the advancements brought by mould making and casting glass and only in 50 BC did blown glass enter the scene.
