Dust vs Steam Plume

Is it a steam plume or a dust plume?

Members of the community advise us that from time to time, they can see a visible plume coming from our kiln stack(s) and they ask if the plume is steam or dust? Often the difference can be determined based on certain characteristics these plumes may display. It is important to remember that due to light refraction, plumes can appear different at different angles around the kiln stack(s) and in particular, from different locations in the community.
