Quink



Quink (a portmanteau word from 'quick' and 'ink') is a fountain pen ink developed by the Parker Pen Company. The ink was novel for using isopropyl alcohol as a solvent, which dried by absorption rather than evaporation of previous water-based inks. However the composition of the ink damaged some pen barrels and caps. The ink was later marketed with the Parker 51 pen, introduced ten years after Quink's release into the marketplace and designed to be unaffected by the chemical properties of Quink.
