About glass and glass products
cpc code 371 covers the glass and glass products industry, a vital component of the broader manufacturing sector. This industry is responsible for producing a wide range of glass-based materials, from basic containers and tableware to specialized technical and architectural glass. Glass products are essential inputs for numerous other industries, making this sector a crucial part of the global supply chain.
Production process
The production of glass and glass products typically involves a multi-step process. First, raw materials such as sand, soda ash, and limestone are melted at high temperatures to form molten glass. This molten glass can then be shaped and formed into various products using techniques like blowing, pressing, or drawing. Depending on the desired end-product, the glass may undergo additional processing, such as annealing, tempering, or coating, to enhance its properties and durability.
Production inputs
The main inputs required for the glass and glass products industry include silica sand, soda ash, limestone, and other mineral additives. Specialized machinery, such as furnaces, molds, and cutting/polishing equipment, is also essential for the various production processes. Energy, in the form of electricity or natural gas, is another crucial input, as the high-temperature melting and shaping of glass requires significant energy consumption.
Production outputs
The glass and glass products industry produces a diverse range of outputs, including 321 Flat glass, 322 Glass containers, 323 Glass products, and 325 Other glass products. These outputs are then consumed by a wide range of industries, such as 326 Construction, 327 Automotive, 334 Electronics and appliances, and 339 Household and personal goods.
