Experimenting with Watercolour

This lesson takes the form of an art-science inquiry workshop. Different substances are available  to use with water colour paint in an experimental art making process. The surfaces used range from tissue paper to canvas paper, again providing a forum for experimentation and discovery.

Results vary as soluble and non-soluble solutions produce different results. Hydrophobic mediums including: acetone/alcohol, wax, gum (masking fluids), salt, dishwashing liquid and vegetable oil can be used.

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.
