Substances mixed with paint or other materials to modify their properties such as flow, texture, drying time, or transparency. THIS IS WHAT PRACTITIONERS OFTEN CALL 'MEDIUM' (e.g., 'glazing medium', 'granulation medium', 'Liquin').

Medium (practitioner sense)
scope note
In oil painting, 'oil medium' refers to additives like Liquin or stand oil. In watercolor, 'watercolor medium' refers to additives like granulation medium or ox gall. This class disambiguates that usage from other meanings of 'medium'.
