1. Glass share of total sodaash consumption
Global market: Glass industry accounts for 5257% of total global soda ash consumption, ranking as the largest enduse sector.
Breakdown within glass segment: float flat glass, PV glass and automotive glass take 6065%; container & dailyuse glass 3035%; special glass for the rest.
China market: Glass consumes 5560% of China’s total sodaash output.
Soda ash dense is mostly supplied for float glass and photovoltaic glass.
Only a small portion of soda ash light goes to container glass; most light soda ash flows to chemical synthesis, detergent, lithiumcarbonate production and other sectors.
Note: Driven by PV glass capacity expansion, glasssector consumption ratio has edged up in recent years.
2. Sodaash mass percentage inside glass rawmaterial batch
For ordinary sodalimesilica glass (majority commercial glass): Soda Ash Dense 1215 wt%
Float building glass: 1214%
PV rolled glass: 1113%
Container glass: 1315%
Automotive tempered glass: 1213.5%
Borosilicate heatresistant glass: only 47%
3. Unit consumption (per ton finished glass product)
Float / PV glass: 0.200.22 tons soda ash per ton glass
Dailyuse container glass: 0.210.23 tons soda ash per ton glass
4. Important clarification
5260% (Global / China): Glass industry’s share of total sodaash production.
1215%: Sodaash mass fraction inside glass batch mixture.
0.200.22 t: Absolute weight of soda ash required for manufacturing one ton glass.
