Answer to Question 1

Answer: They spray synthetic resin fixatives over the finished work.

Answer to Question 2

Answer: The two categories are dry media (metalpoint, chalk, charcoal, graphite, etc.), in which pigments, sometimes ground or mixed with dry binders, are applied to the surface of a work, and wet media (pen and ink, wash and brush), in which pigments are suspended in a liquid binder and applied to a surface with a pen or a brush.
