PREPARATION. 
Regarding the preparation of fullers’ earth, F. B. Van Horn 
says; 1 “The fullers’ earth in Florida is usually mined by pick 
and shovel, and hauled to the mill, where the earth is broken 
up into small lumps and put through rotary driers. It is then 
taken by elevator to the crushers and ground and bolted into 
several grades, 120 mesh being the finest. The material is 
then ready for shipment.” 
USES. 
Fullers’ earth is used in the meat packing industry to clarify 
lard. The earth is usually ground to 120 mesh and is generally 
of English origin. 
In the refining of petroleum a considerable quantity is 
used. For this purpose the earth is not ground so fine. 
Small quantities are used to remove grease from woollen 
goods.

The price of fullers’ earth laid down at the points of con 
sumption varies from $14 to $17.
