+Predefined Mixtures
+-------------------
+
+A number of predefined mixtures are included in CoolProp.  You can retrieve the list of predefined mixtures by calling `get_global_param_string("predefined_mixtures")` which will return a comma-separated list of predefined mixtures.  In Python, to get the first 5 mixtures, you would do::
+
+.. ipython::
+
+    In [1]: import CoolProp as CP
+    
+    In [1]: CoolProp.CoolProp.get_global_param_string('predefined_mixtures').split(',')[0:6]
+    
+and then to calculate the density of air using the mixture model at 1 atmosphere (=101325 Pa) and 300 K, you could do
+
+.. ipython::
+
+    In [1]: import CoolProp as CP
+    
+    In [1]: CoolProp.CoolProp.PropsSI('D','P',101325,'T',300,'Air.mix')
+    
+Exactly the methodology can be used from other wrappers.
