It would be characteristic, perhaps, of the air currents, but not of 
something about the nature of the substance - that a particular 
substance makes particular patterns of steam (or rather, again, mist) is 
already firmly within the realm of "because it's magic". In the physical 
realm, the composition of the substance isn't going to influence the 
behavior of any mist coming off it. The temperature would cause it to 
rise (or fall, as with dry ice) at a different speed, and the air 
currents in the environment around it would be what have a 
"characteristic pattern".

Now, the helix pattern you sometimes see rising off of ACTUAL hot 
substances, coffee etc, is because the air around them is rotating as it 
rises, carrying the visible mist with it. But that is NOT necessarily 
going to be what a MAGICAL substance does.

Random832:
Don't you DARE presume to tell me what I did or did not visualize! I 
posted a PICTURE of what I visualized, and it was NOT a helix! what I 
visualized was emphatically not the path traced by a point that is 
rotating at a fixed radius about an axis in a plane while travelling 
along that axis perpendicular to the plane of rotation; it was the path 
traced by a point that is rotating at a decreasing (or increasing - i 
actually had it increasing, but the point fixed and the plane rotating, 
but the end shape is the same) radius around a single point within a plane.
