Manufacturers of quality flat glass, glass containers and detergents rely on the purity of ANSAC dense soda ash in making the world-class products their customers demand.

ANSAC dense soda ash is a premium quality product that combines a consistently high sodium carbonate content with very low impurity levels of chlorides and iron. ANSAC dense soda ash is guaranteed to be 99.2% pure, but has a typical purity level of 99.8%, resulting in more product when compared to a lower assay soda ash.

Key advantages of ANSAC dense soda ash include:

Particle Size Uniformity
ANSAC's dense soda ash is closely and consistently matched to sand grain size resulting in a homogenous sand/soda ash mix in the glass furnace. This provides predictable, controllable viscosity resulting in a final glass product that is free from distortion.
Fewer Issues with Soda Ash Fines
Because 97% of ANSAC Dense Soda Ash particles are 75 microns or larger, users will enjoy a more homogenous sand/soda ash mix. This actually saves money since fewer soda ash fines will be blown off and lost during production. In addition, furnace life may be extended since liquid soda ash particles, which dissolve refractories, are minimized in the gas stream. Finally, the narrow distribution of particle sizes, combined with low fines, results in less dusting and easier handling of the product.
Lower Chloride and Iron Levels
Chloride impurities in soda ash are harmful to the environment and to the life span of the molds and furnaces involved in glass manufacturing. The low chloride values of ANSAC dense soda ash result in less air pollution. Additionally, by producing lower exhaust temperatures during glass manufacture, furnace and mold life is extended. ANSAC dense soda ash also has relatively low levels of iron. This enables glass manufacturers to utilize cheaper, high iron sands while continuing to produce a glass that meets their standards for clarity.

About Soda Ash - ANSAC

These have the same chemical properties and only differ in physical characteristics, such as bulk density and particle size and shape (which affect flow characteristics and angle of repose). The Federal Reserve Board incorporates monthly soda ash production data into monthly economic indicators used to monitor the condition of the U.S. economy.


Medium Dense Soda Ash - ANSAC

It offers a competitive alternative to synthetic light soda ash by absorbing high levels of liquid while precluding the dusting and segregation problems often associated with lighter synthetic soda ash. Quality detergent manufacturers look to ANSAC medium dense soda ash as an attractive alternative to ANSAC dense soda ash or synthetic light soda ash.


Health and Safety - ANSAC

ANSAC is committed to ensuring the safety of people and the environment and consistently aims to maintain the highest standards of safety and quality in all that we do worldwide. Personnel entering bins or silos containing soda ash must wear safety belts properly roped to rescue facilities and be physically observed by someone not on the soda ash pile.


Quality & ISO 9001 - ANSAC

The primary responsibility for guaranteeing compliance with product specifications lies with the producers, but periodic sampling is conducted by ANSAC as follows. When laboratory analysis is required ANSAC contracts the work out to independent labs or utilizes member company laboratories. All soda ash sold by ANSAC, and produced by our three U.S. suppliers, is manufactured in ISO 9001 certified plants.
