What is a blocker?
The block is a dense amber, almost colorless to dark reddish yellow. Amber is a resin of the Tertiary Coniferous plant. It is buried underground by geological processes. After a long geological period, the resin loses its volatile components and polymerizes and solidifies to form amber. It is often associated with coal seams.
