Hydrophilic and Hydrophobic of materials in context with Watercolour painting 

​

• Paint is differed by three main types: Water, Polymer (acrylic) and Oil

• To understand the molecules of these properties of fluid is to understand what will and will not work

• Water is small particles.

• Oil is large particles.

• Polymer is a human made substance that occurs when there are more than one monomer. When the liquid (water) in the acrylic is evaporated, it forms a tightly fitted, dense SOLID known as polymer. Once it takes on this state, it cannot be reversed unless heated (to disperse the monomers).

• Oil floats on top because it is a large particle, however it's DENSITY is less than water.

• Water can thin down polymer in its liquid state because it disperses the monomers before the liquid content (water) has evaporated. However; in its state after evaporation, it still forms 'plastic' just thinner since the particles have become less dense and have to stretch further to connect ( a physical not chemical reaction).

• Oil, never actually dries. It has nothing to be evaporated and therefore can never actually be dry. It can only oxidise on contact to air and become a matter than seeps and soaks into materials that allow it (becoming a binder), or it can exist forever until it is heated and burnt at a high temperature where it; due the oxygen in fire - fully oxidises it making it a gas (what we smell).

• Painting as a verb is the process of using FLUID state material, a PAINTING as a noun is the product of fluid become SOLID in state through evaporation or oxidation of the material.

• Watercolour blocks are but heavily condensed pigment.

• Watercolour paint is pigment with a water-soluble natural gum

• Acrylic paint or polymer, is pigment with the chemical makeup of polymer in its liquid state in synchrony with water.

• Oil paint is pigment with linseed oil.

• Oils can be slow drying and fast drying.

• Paint can be made with anything liquid in conjunction with pigment.
