eco friendly paints

In this article, we will learn about them eco friendly paints. During the curing and evaporating process, paints release their solvents in the atmosphere. You remember our articles explaining solvents right?
The release of these Volatile Organic Compounds (VOC’s) into the atmosphere, can precipitate effects ranging from Ozone Depletion, to smog, and yes, to Global Warming too. Public sentiment has only been getting stronger in the past few years, and unlike the 1990’s, where the introduction of Green paints bombed, the latest revolution is not going to end.

The crux of the matter however, is that painting experts maintain that, despite what the marketers say, paints without VOC’s don’t perform as well as paints that have them. They claim that they require more coats to achieve the same finish, and are not as long lasting.
However, with VOC’s being linked to dizziness, and asthma, public demand is only getting stronger, and the industry has no choice but to respond.
One solution, is to use Latex Paints, that are water based, with an acrylic resin acting as a binder. In addition to being environmentally friendly – Water based means no more VOCs – Latex paints have several other advantages over traditional paints including washability, and better opacity (Ability to completely cover another color).
Of course, being water based means that the Latex paints cannot be used to paint iron, as it will speed up the rusting process. Even so, there is a distinct trend towards latex paints, and new innovations are popping up everywhere.
The term ‘Green Paints’ can not only refer to the overt effects of the paint itself, but the manufacturing process that is followed in order to obtain the paint ingredients. For example, Titanium Dioxide, is widely used in paints for it’s whiteness, and for the fact that it has high ‘Hiding power’. This refers to the refractive index of the material. If the refractive index is high, it will provide greater opacity when it is disbursed in a solvent.

However, Titanium Dioxide is manufactured by processes called the sulphate, and chloride processes that resulted in diluted Sulphuric acid being created as a by product. These were dispersed into the sea, prompting debate on whether or not this was acceptable. It also meant that all substances that were dissolved in the acid, would also be released into the sea.
Quite apart from more efficient manufacturing practices, Titanium Dioxide, when applied as an exterior coating, reacts with sunlight causing smog. The International Agency for research on Cancer (IARC), has also classified Titanium Dioxide as an IARC Group 2B carcinogen, which means that it is probably an agent leading to the promotion of cancer in humans. Despite this, Titanium Dioxide is widely used.
Given the serious health and environmental damage that paints can have directly through their effects, as well as indirectly through their manufacture, Eco Friendly paints are set to have a major impact on the industry, as well as changing the way we view paint.

3 Easy Steps to Measuring and Proportions in Figure Drawing

Proportion is a word often associated with another word for artists, stress.  But I’m here to share with you that it doesn’t have to be a stressful word. Can this really be true?  A simple way to warp speed techniques when measuring proportion?  Yes, I’m here to say that it is true.

Proportion…How big should the head be?  How long should the legs?  How long should I draw this line?  These are questions, we as artists, face everyday.  It doesn’t matter what kind of artist you are…getting the most out of figure drawing with accurate proportions will explode your art to new levels. There are several tools and methods to help artists with proportions.  Without correct proportions, your figure will be inaccurate and lacking at best.

There are certain proportion formulas, such as the figure being a certain many heads tall, or the head of the figure being so many eyes wide.

I like to know these formulas and use them as a guide.  The human form being so individual you can never go strictly off of these formulas alone.  As an artist, it’s important to know these formulas to be able to recognize the deviations from the formulas in the model/subject you are drawing.

Measuring

Measuring is a little bit different for every artist.  It is a tool for proportions not to overlook.  Just as someone aiming a poolstick or firing a gun does it differently than the next person, so goes it for the artist.  Some artists, while measuring, will shut the left eye and some the right, while others will keep both eyes open (just never keep both shut LOL).  You’ll need to see what’s right for you.  Then, hold your pencil between your thumb and fingers with your fingers wrapped around the pencil.  Measure from the top of your thumb to the end of your pencil.  You can hold your pencil vertical or horizontal for this technique, keeping it at shoulder high.

Your measurement from your thumb to the end of your pencil may only be ½ inch, but on your drawing it could be an inch or more.  All of your measurements are comparative.  For example, if an artist wants to know how long a leg is, he can compare it’s length with the length of the subjects head.  Using the measurement method we discussed with the pencil, it’s easy to compare.

These simple methods, once applied, will soar your drawings, paintings or whatever you are working on.  The advice practice, practice, practice, coupled with masterful technique will help you advance your art quickly and masterfully more than anything else.

This is a brief overview on proportions and measuring.  For more information on proportions, measurements, drawing people or faces, and much more…
