Sodium Carbonate, Dense (Heavy Soda Ash)

Dense soda ash (heavy soda) is anhydrous sodium carbonate that, unlike light soda ash, has been brought to a higher bulk density by enlarging its particle size; its chemical identity is the same as that of light soda ash. Dense soda ash is preferred in glass production because dust loss is low and dosing is easier; it is also used in the detergent and chemical industries.
