Dense soda ash is mainly sodium carbonate with two water molecules and is produced by densification and crystallization of light ash. Its density is almost double that of light ash. Dense soda ash dissolves readily in hard and soft water.
Soda Ash Dense is preferred for all kinds of glass manufacture like flat glass, float glass, container glass, etc.
