text: Except in the case where sodium carbonate monohydrate is the crystallization product of the crude trona solution, the invention has the further advantage that the bulk density of sodium carbonate or soda ash may be controlled and increased by the high temperature calcination, whether said sodium carbonate is formed by the calcination of sodium sesquicarbonate, sodium bicarbonate, light soda ash (sodium carbonate), or other forms of sodium carbonate crystals Without going through the step of forming sodium carbonate monohydrate from previously calcined light soda ash, as is the present practice.
