Manufacture and processing of other glass, including technical glassware

NACE v2.0 Code: C23.19

About manufacture and processing of other glass, including technical glassware

NACE code 23.19 covers the manufacture and processing of a wide range of glass products, including technical glassware, laboratory equipment, and specialty items. This industry plays a crucial role in supporting various sectors of the economy, from scientific research and medical diagnostics to construction and consumer goods. The production of these specialized glass products requires advanced techniques and expertise, making it an important component of the broader manufacturing landscape.

Production process

The manufacture of glass products under NACE code 23.19 typically involves a multi-step process. First, raw materials such as sand, soda ash, and limestone are carefully measured and mixed to create the desired glass composition. The mixture is then heated to high temperatures, often in a furnace, to melt the materials and form a molten glass. Depending on the final product, the molten glass may be shaped using techniques like blowing, pressing, or drawing, before being annealed (slowly cooled) to ensure the desired strength and durability.

Production inputs

The primary inputs for the NACE 23.19 industry include silica sand, soda ash, limestone, and other mineral additives that are used to formulate the glass composition. Additionally, the industry relies on specialized equipment and machinery, such as furnaces, molds, and cutting tools, to shape and process the glass. Energy sources, such as natural gas or electricity, are also crucial for the high-temperature melting and shaping processes.

Production outputs

The NACE 23.19 industry produces a wide range of glass products, including laboratory glassware, scientific instruments, lighting components, and various types of technical and specialty glassware. These outputs are often consumed by other industries, such as 72.11 Research and experimental development on biotechnology, 86.10 Hospital activities, and 23.11 Manufacture of flat glass, which use the specialized glass products in their own manufacturing or research and development processes.

Revisions to 23.19

Classification codes are adjusted frequently. The code may have been revised or replaced between system versions. The table below shows the history (newest to oldest) of the code 23.19. The most recent 1 version of this code (23.19) is in the NACE v2.1 system:
