Tequezquite  is  the  name  given  to  saline  efflorescences,  containing 
sodium  carbonate,  and  met  with  in  different  parts  of  Mexico.  The 
purest  is  "tequezquite  espumal"  from  the  northeastern  part  of  Lake 
Texcoco,  and  contains  according  to  Hay,  anhydrous  sodium  carbonate 
516,  sodium  sulphate  153,  sodium  chloride  0'45,  water  246,  earthy 
matters  O30.  "Confitillo"  contains  28  per  cent.,  and  "Cascarilla" 
20  per  cent,  of  sodium  carbonate,  both  containing  30  to  35  per  cent, 
of  earthy  matters.  A  very  impure  variety  is  "Polvillo"  with  5 
sodium  carbonate,  1*5  sodium  sulphate,  6  sodium  chloride  and  85 
earthy  matters.  The  article  is  used  for  alkaline  baths,  and  for  the 
manufacture  of  soap  and  of  sodium  carbonate.
