March 26, 2020

Election Commission has decided to allow usage of indelible ink on persons for stamping for home quarantine by health authorities in view of COVID-19.

About:

Indelible ink refers to the violet-coloured ink in India that is applied on a voter’s forefinger after she exercises her vote.
It is known to contain silver nitrate and is manufactured in secrecy. Indelible ink remains bright for about 10 days, after which it starts fading.
In 1962, the Election Commission in collaboration with the Law Ministry, the National Physical Laboratory of India and the National Research Development Corporation made an agreement with Mysore Paints and Varnish Ltd. to manufacture ink that couldn't be wiped off easily.
Mysore Paints and Varnish Ltd. was founded in 1937 by Maharaja Krishnaraja Wadiyar IV. The company is the sole supplier of indelible ink for civic body, Assembly and Parliamentary polls. It also supplies ink to about 25 countries.
