Art Technical Terms Explained!...

By Anna Meenaghan

What is Paper Mache? Basically, with this you get some newspaper and rip it up. Pummel it with water which leaves you with a soggy lump. At this stage it is ready for you to mould it into any shape that you like.

When it is at the wet stage, you then add glue to it. Once you have acquired your required shape you have to leave it to dry. Similar to wood you can then put a primer on it, before you go on to paint your article.

The advantages with this being that this medium is both strong and yet also light. This is so useful as it can be used to create so many things.

So who would have thought you could make paper from the Sugar Cane plant? Yes, this is true, it is made from the actual husk. It can be used as a drawing surface, but is very good, in fact, for paper mache too, as it is very absorbent. Even though it is thick and fibrous, it can be torn easily and it comes in a selection of colours.

Gesso - This is a priming coat for canvas or other surfaces before you actually start to paint. It is a sort of glue. This normally consists of whiting, chalk, white pigment or plaster.

This gesso, you will find, will make a seal on your surface which, you ought to discover, is reflective too, better as the canvas doesn't roll.

Impasto is a surface which is textured and paint strokes make impressions on it with their bristles. Impasto itself is made by using a palette knife or paintbrush and then filling them with paint to be put on to the canvas. This creates layers of paint.

What is pigment? This is what is used to dye or colour the paint itself. This, as a paint medium, is made from minute particles as they have been ground very finely. In time gone by the consistency came from animals, plants and minerals. Nowadays a lot are made from synthetics.

Embossed - This is a pattern which has been marked or stamped on to the surface and in some cases carved. It can also be used with metal and a hammer.

Fixatives are a way of trying to preserve your painting. These can be sprayed or brushed on.

Positive and Negative Shapes - If you take the time to consider the shapes inside a painting or drawing, they fall into two categories, positive and negative. The positive shape will be the main parts or objects.

Whatever you have bordering the positive, will be the negative shape. However, you need to work equally on both sections to reach a successful conclusion.

Grid is when you draw square boxes on to a card backdrop for still life drawings. This makes it much easier to decide where the shadows and shapes should be positioned on your drawing.

Acrylic Retarder is used to lengthen acrylics open drying time. Maximum use of 10% with acrylic is recommended. This is pretty handy when shading or blending in Wet in Wet techniques and it helps to combat skin forming on your palette.

Acrylic Gloss Varnish, if mixed with colours, will increase the way the paint flows, also their transparency and luminosity. This is good for quick drying glazes. It also makes your brush strokes blend well on your surface and is certainly flexible.
