Short summary

Mineral dust particles are known to act as effective ice nucleating particles in the atmosphere and to play a role in the glaciation of mixed phase clouds. We have measured the ice nucleation activity of 15 different feldspar samples using a droplet freezing experiment and shown that alkali feldspars nucleate ice much more efficiently than plagioclase feldspars. We have also shown that certain "hyper-active" alkali feldspars nucleate ice very efficiently compared to typical alkali feldspars.
