PAINTING MEDIUMS

·        Encaustic: Encaustic, which means ‘to burn in’, is an ancient Greek painting technique, also known as hot wax painting. It is done by combining hot beeswax with colouring pigment. Encaustic wax has many of the properties of oil paint: it can give a very brilliant and attractive effect and offers great scope for elegant and expressive brushwork. The wax has to be reheated to be manouvered after applying to the surface which is usually wood or canvas. It was used to make portraits by the Greek to honour the dead.

·        Tempera: Tempera was the original mural medium in the ancient dynasties of Egypt, Babylonia, Mycenaean Greece, and China. This medium combines egg yolk with pigment. It was used to paint religious Christian icons. It is permanent, fast-drying and has to be applied on stiff support as it’s not flexible. However, this medium is said to be 'temperamental' as it’s consistency has to be delicately balanced by changing the amount of yolk and water.

·        Fresco: Fresco paintings were used on plaster and ceilings. This medium was popularized during the Renaissance by painters such as Leonardo da Vinci and Michelangelo. Buon fresco was used on wet plaster, combining water with pigment. When the plaster dried, it sealed the paint making it durable. Secco fresco was painted on dry plaster and hence needed a binder to hold the paint together.

·        Oil: Oil paintings use pigments combined with drying oil as a binder. It was a technique developed in the 15th century and is still famous among artists because of its durability and versatility in texture due to which on balancing the amount of oil, the paint can applied thinly giving a transparent effect or like a paste with a pallet knife. Its slow drying nature allows an artist to work on the painting for days even months. It can be applied in layers, with each layer increasing in the amount of oil. Oils act as a great medium for obtaining a variety of colours. They have to used in well ventilated places as the oil used in thinning or binding release fumes which can be suffocating and toxic. Oil paints have to be used with extreme care as the brushes and paints cannot be used with water. They also take a lot of time to dry between layers which can increase the duration of painting.

·         

·        Watercolor: Watercolour is the easiest medium to use and often children are taught to use it in schools. They are water soluble and are dissolved in large amount of water to obtain thin layers of translucent colours that can be build to form detailed artworks with depth. They have a matte finish and are preferably used on watercolour paper which thick like blotting paper which can absorb water without changing its texture.

 

·        Gouache: Gouache is similar to watercolour but it is more opaque in nature. Gouache has a considerable history, having been used for at least twelve centuries. It can be used to paint lettering or fill in drawings, it allows flexibility because mistakes can be covered up, and it photographs well — an important attribute in the age of digital illustration and design.

 

·        Acrylic: Acrylic paint is the most recent medium in this article, with the first synthetic use dating back to 1940s. It is a mix between oil paints and watercolours. Acrylic paints have a huge versatility as they come in bold colours and their consistency can be changed by using synthetic mediums such as gel and matte for thick textures which give glossy and opaque finish respectively. These mediums can be used for impasto techniques. Retarding mediums can be used to slow the drying time as the acrylic paint dries very fast once exposed to air and this medium makes them resemble oil paints. On adding excessive water they act like watercolours. Acrylics are also efficient because they use water as medium compared to oil paints and can be removed from surfaces by peeling.

My TKS Application journey

Published on
My journey  I applied for The Knowledge Society in February 2022. Initially, I had opened an application but then decided not to go for it, thinking that I wasn't smart enough to get in. Mia Nguyễn was my application advisor who mailed me about my incomplete application, asking me if there was anything I needed help with. There were few interview slots remaining and she asked if they should close my application. I opened her mail and began typing an apology letter, telling her that I would not be applying. As I finished the letter, my finger hovered over the send button. I sighed, selected my mail and pressed backspace. What was the harm in trying? I typed out a quick message, asking her to hold my slot. I opened MS Word and started on the essays I needed and stayed up all night, only to submit them a few hours before the deadline.  In late April, I was accepted into the 10 month Global Virtual Program as a TKS Innovator with considerable financial aid. Unfortunately, my finan...

The summer of the beautiful white horse: Analysis, Summary and Theme

Published on
The summer of the beautiful white horse. : An Analysis  This short story written by William Saroyan is part of the CBSE Class 11 Snapshots NCERT Syllabus. While high school students would certainly benefit from the articles, literary enthusiasts are encouraged to join the discussion of how the author uses diction, literary terms and tone to portray the meaning of through the text.   Nostalgia marks the tone of narrator in the opening line of the sentence, reminiscing over how the world used to be magnificent and delightful. The sentence “life was still a delightful and mysterious dream” aptly describes how the narrator perceived the world as a nine year old. The theme of exaggeration and awe is repeatedly seen throughout the story through the character of uncle Khosrove and the narrator’s admiration of the horse. So awe stricken was Aram that he could not believe his eyes when his “crazy” cousin Mourad brought a beautiful white horse outside the window of his room around daybr...

How do animal cells move? | Motor proteins and cytoskeleton in cellular biology

Published on
Cells move around the body using cellular extensions of the plasma membrane like cilia and flagellum. They take the help of fibres outside the cell to provide anchorage. These extensions are made of microtubules, sliding against each other to produce a back and forth motion. These microtubules are a part of the cytoskeleton which will be discussed shortly. Within the cells, motor proteins attach to the receptors on organelles and use their ‘feet’ to ‘walk’ them along the fibers of cytoskeleton to their required location. Source: Campbell Biology, 12th edition  These motor proteins consume ATP (Adenosine Triphosphate) which is the source of energy at the cellular level. It is the energy currency of the cell as it provides readily releasable energy due to breaking of bonds between second and third phosphate groups. Now that we have understood the mechanism for cell locomotion, let’s understand more about the cytoskeleton and how its elements aid in the process. Exis...
