| Shellac |
Shellac is mainly produced in India
and Thailand. Smaller quantities come from China and Vietnam. The
product is manufactured in a process known since the old times as
melting filtration. Nowadays hiqh-quality, dewaxed and decoloured
Shellac is won by an extraction process using solvents.

Shellac is
excreted by the shield louse (latin: Kerria Lacca), which belongs
to the family of Coccidae. In India, it is also known as
“Lakhsa” - a word coming from Sanskirt meaning “hundred
thousand”. Trees and their branches are being infected with
Brut-Lac, from which the shield louse, who usually has a lifespan
of about 6 months, feeds. The encrusted brances are then collected
and the excrete is chopped off into small pieces. At this stage,
the product is called “Sticklac”. The Sticklac is then refined
by removing insect remains and small wooden pieces. Then it is
crushed and washed in cold water in order to remove the dye (Lac
Duy). When the Sticklac has dried off, the remains is a redish to
brownish material called “Seedlac”. All Shellac qualities are
manufactured from Seedlac by further refining.
