Drip coagulation

Mechanically strong spheres of this size are produced by extrusion, granulation, or drip coagulation. 

Latex continues to drip after the initial collection and coagulates naturally in the cup to form cup lump. Coagulum which forms as a film of latex on the tapped cut, called tree lace, or from latex that has dripped onto the ground, called earth scrap, is collected the next day along with the cup lump. Some smallholders may not collect the latex at all, but allow it to coagulate in the cup and collect it as cup lump. AH these methods produce mbber known as field coagulum. 

A blanket crepe mbber produced from the dried films and lumps of mbber found in the tapping cups at the beginning of the next tapping. Cup lump results from the spontaneous coagulation of the latex which has dripped from the tree after the cup has been emptied of the main flow.
