Fascinating World of Pigments and Paints

In addition to painting houses, paints are used to give color to automobiles, underground storage vessels, road markings, ships and many more items.

The element in paints that is responsible for lending color to several applications is pigments. Pigments hold a place of great importance in the paint industry with huge quantities of the several varieties being used for different purposes. Pigments in paints act as colorants in commercial, industrial and decorative applications. The different type of pigments for paints can be listed as below:

Earth Colour Pigments: These are obtained from natural sources and are classified as inorganic pigments. They are weather resistant, light fast and chemical fast. Some examples under this category are Umber, Ocher, Swedish red, Bolus etc.

Mineral Pigments: These are classified as synthetic inorganic pigments. A few of the pigments included in this category are Chrome oxide green, Titanium dioxide, Ultramarine variety of pigment blue, Iron oxide yellow, Nickel titanium yellow etc.

Plant Colour Pigments: These are obtained from natural organic pigments available in plants. Some examples that come in this category are Saffron, Indigo, Alizarin red, Reseda, Woad etc.

Synthetic Pigments: Some synthetic pigments also find their way into the paint industry. Phthalocyanine, Azo, Dioxazine are just to name a few of them.

The pigment in paints not only acts as a colorant but also offers the underneath surface protection from weathering and corrosion. It is in fact responsible for holding the paint together. Special pigments are used in specific applications such as providing metallic finishes to automobile bodies or offering long lasting feature for road markings. In addition to pigments, paints contain binders and solvent.

The binder helps in holding the coating of paint to the substrate. Solvents also called as thinners act as a medium in which the binder, additives and pigments are dispersed as true solutions or as colloidal dispersion. The pigment, binder and the solvent have to be mixed in the right proportions so that the final finished output is a smooth, continuous and attractive coat of paint. The paint technologist and the paint technician work in conjunction to achieve the desired final product.

With industrial applications of paints ranging from aerospace, coil, automotive to architectural and decorative, paint formulations have to fulfill varied technical criteria besides offering durability, opacity and ease of application. It is the job of the paint technologist to formulate the paint as per pre-determined standards and the paint technician who is responsible for its manufacture to ensure the achievement of the features set down by the paint technologist. The equipment that is commonly used in the manufacture of paint includes ball or pebble mills, vertical and horizontal bead mills and top speed intensive stirrers. The paint manufacturer can make use of several other machinery that is available for the purpose. The efforts of all are however, directed towards obtaining top quality paints!

Painting Landscapes With Acrylic Paints – 3 Techniques

Do you enjoy using the paint directly from its container?

Acrylic paints can be directly applied to the selected surface or canvas. The versatility of this paint will allow you to use all three methods to create the desired illusions. Acrylics open a world of choices for texture. Have fun with it.

Do you like the texture and thickness of oil painting?

The higher the content of tint; the less liquid filler is used. This is the higher quality of paint and it will cost you a few more dollars per container. This paint will be thicker and richer because of the increase of color and it will give the appearance of oil paint. Oil paint has toxic fumes. Acrylic paints are nontoxic.

Pencil Sketching

Sketching ahead will allow you to make corrections and see the final product in the penciled form. If you are using a graphite pencil, use light strokes. The acrylic paint may not cover your pencil marks.

Some artists like to sketch with colored pencils to discourage unwanted visible markings under a thin layer of paint. Sketching before or after applying a layer of background paint will be a personal choice.

Paint Sketching

Painting without sketching is freedom to be challenged by errors and happy accidents. You will be placed into the unknown. Your colored creation will take many twists and turns as your landscape painting is born on canvas.

Use a soft broad brush to make a series of horizontal, vertical, or interweave strokes. Use a smaller brush or tool substitute tinted with paint to sketch trees, waterfall, shrubbery, road, fencing, and other landscape features as guidelines. Upon completion of sketching, return to fill in details to finalize the landscape.
