Bioart is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes. Using scientific processes and practices such as biology and life science practices, microscopy , and biotechnology (including technologies such as genetic engineering , tissue culture , and cloning ) the artworks are ...
This is the chemical reaction in which chemical energy is converted to light energy. It is estimated that 90% of deep-sea animals produce some sort of bioluminescence. Considering that a large proportion of the visible light spectrum is absorbed before reaching the deep sea, most of the emitted light from the sea-animals is blue and green.
Agar plates are used as a canvas, while pigmented or fluorescent bacteria and yeasts represent paint. In order to preserve a piece of microbial art after a sufficient incubation, the microbe culture is sealed with epoxy. [2] Microbe species can be artistically chosen for their natural colours to form a palette.
Ochre, iron oxide, was the first color of paint. [7] A favored blue pigment was derived from lapis lazuli. Pigments based on minerals and clays often bear the name of the city or region where they were originally mined. Raw sienna and burnt sienna came from Siena, Italy, while raw umber and burnt umber came from Umbria. These pigments were ...
Low-VOC paint types include latex (water-based), recycled latex (water-based), acrylic, and milk paint. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC. [citation ...
A common characteristic of Red Lake pigments is their translucency. especially in oil painting. Painters often created more vivid colors by adding layers of red lakes over less transparent underfloors, particularly painting over lake colors mixed with lead white or vermilion. A weakness of lake pigments is their tendency to fade because of the ...
Paint can be made in many colors and types. Most paints are either oil-based or water-based, and each has distinct characteristics. Primitive forms of paint were used tens of thousands of years ago in cave paintings. [1] [2] Clean-up solvents are also different for water-based paint than oil-based paint. [3]
Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects.
