Machine-drawn glass: 1915-1950
Even beyond the Victorian era, the age of a property determines the most authentic glass type to use in replacement glazing. Machine-drawn glass is ideal for properties constructed in the early to middle twentieth century.
Histoglass offers genuine machine-drawn glass with both our Thin Double Glazing and our MONO single-glazing systems. Imitation period glass, even for relatively modern eras, can spoil the effect of replacement glazing. Discover the benefits of real period glass.

What period does machine-drawn glass suit?
Machine-drawn glass was first produced in the early 20th century, so it’s suitable for British period properties dating from 1915 to around 1950.
How is machine-drawn glass made?
Our machine-drawn glass is made using the Fourcault principle, developed in the early 1900s in Belgium by Émile Fourcault. It uses a vertical ‘draw’, aided by gravity, to form the glass.
The process involves glass being drawn directly from the tank at the working end of the furnace. A boat-shaped slotted block, made of refractory material, is pushed down into the molten glass. As the hot extruded glass rises through the slot, it is grasped by an iron bait.
The cooled glass then adheres to the bait and is pulled upward between water-cooled tubes, during which time it is toughened. When it reaches the top of the machine, it is cut by automatic cutters. These are then reheated and flattened.
