Transparent flat glass for furniture or industrial use accounts for over 90% of global glass production. Primarily manufactured using the float system—developed by Alastair Pilkington in the 1960s—transparent flat glass is suitable for technical-industrial applications and is widely used by design, architecture, and interior decor professionals to create tables, display cases, desks, bathroom and kitchen tops, precision components, and much more.
The Production of Transparent Flat Glass
Let’s explore how transparent flat glass is made using the float technique. To obtain flat glass, a homogeneous mixture of silica, soda, and lime must be brought to its melting point along with glass cullet, alumina, and other oxides used as colorants. This liquid mixture is poured onto one end of a bath of molten tin in a controlled atmosphere. Due to the floating effect, the glass spreads across the entire surface of the tin bath, forming a smooth and uniform layer on both sides that cools and solidifies into a continuous ribbon. Finally, the transparent flat glass sheet is reheated on both sides for polishing, ensuring two perfectly parallel surfaces and a flawless finish.
Flat glass can be transparent or colored. Naturally, transparent flat glass covers the majority of industrial demand as it adapts to any type of project. Produced in standard thicknesses ranging from 2 to 25 mm, float glass is not inherently suitable for architectural applications because it shatters into large, sharp pieces. For structural and architectural use, transparent flat glass sheets must be tempered or laminated to become true safety glass, capable of withstanding thermal and mechanical stress while ensuring domestic comfort.
The Applications
The use of glass in architecture and for structural purposes is governed by strict legal regulations. For further information, please refer to the pages dedicated to accident-prevention glass, safety crystals, armored, laminated, and tempered glass. Structural uses are described in detail in the sections on self-supporting glazing, U-Glass, the Spiderglass fixing method, and technical industrial glass.
