The Calcutta market will not accept machine-made shellacs 
as TN. They are therefore made and sold as proprietary marks. 
The marks quoted by Messrs. Moran are— 
Angelos’ TN 
T. Nr. 
Angelos’ TN No. 2. 
Bleached shellac , though not exactly a separate grade, is a special 
form of shellac used in making white varnishes and for other pur¬ 
poses in which a white colour is required. There are various methods 
of preparation which are described by Puran Singh, usually a reduc¬ 
ing agent is employed of which chlorine is the commonest. Bleached 
shellac rapidly loses its solubility unless kept under water and it 
must therefore be made immediately before use. Its manufacture 
in India for export is thus hardly a practical proposition. 
Shellac inferior to TN is known as “ dom” It is not generally 
recognized as a definite grade but is bought and sold at a discount 
on the current rate for TN. A notoriously poor class of shellac is 
manufactured at Imamganj, and the use of the term “ Imamganj ” 
has now broadened so as to cbver any inferior TN. 
Button lac is sold at a lower price than shellac of the same grade, 
as it does not go through the process of stretching, and hence the 
cost of manufacture is less. It is not so popular in foreign markets, 
as it has generally to be ground before use. There are roughly four 
grades :— 
(a) Pure Button lacs made from good grain-lac and graded 
up in values from the equivalent of Standard I shellac 
to that of D.C.—V.S.O—Octagon B. 
(1 b ) Pure Black Button lacs made from kiri , molamma , etc., 
and sold at about TN prices. 
(c) Button lacs made from good grain-lacs, but containing 20 
to 30 per cent, of rosin and sold in various grades, some 
cheaper others dearer than TN. 
(d) Black Button lacs made from kin, molamma , etc., but 
with rosin admixture and sold much below TN rates.
