The Ashes 2021-22 will have a seemingly different ball than the one used in the previous Ashes of 2017-18 Down Under. The new ball is supposed to swing more and have shine on it for a longer period of time than has been the norm thanks to the tweaks applied by the manufacturer Kookaburra.
According to The Sydney Morning Herald, the new ball is likely to keep moving through the air and off the seam in a much more sustained manner. This will be due to a double coating of lacquer that helps the whole ball retain its hardness for longer.
The Gabba pitch right ahead of the first Test match has indicated that it might have a rich coating of grass, which in turn might act as a big booster for pace bowlers from either team.
The double coating of lacquer is not the only change, rather it is the plastic lining under the leather that would make it sustain its hardness, shine and swing for a longer period. This was done by the manufacturer on request from Cricket Australia.
