Lichen

A lichen is a composite organism that algae or (and) cyanobacteria living together in fungus. algae or (and) cyanobacteria produce food for fungus by photosynthesis. And fungus protect algae or (and) cyanobacteria from the environment, fungus gather also moisture and nutrition from the environment. They have a good symbiotic relationship.

Lichens occur from sea level to high alpine elevations, in a very wide range of environmental conditions, and can grow on almost any surface. Different kinds of lichens have adapted to survive in some of the most extreme environments on Earth: arctic tundra, hot dry deserts, rocky coasts, and toxic slag heaps. They can even live inside solid rock, growing between the grains. Some lichens do not grow on anything, living out their lives blowing about the environment. It is estimated that 6% of Earth's land surface is covered by lichen.

distinguish points of Lichen

1. Lichen can live a vary wide range of environmental conditions. They can grow on almost any surface. Different kinds of lichen have adapted to survive in the most extreme ecological conditions. Even they can survive in space station outside of earth.

2. Lichen takes up a huge amount of carbon dioxide from the air which is released by the burning of forests and other biomass. Max Planck institute of Chemistry discovers that lichens, mosses and algae take up approximately 14 billion tons of carbon dioxide and fix approximately 50 million tons of Nitrogen per year. The especially huge amount of Nitrogen fixed by them and nitrogen is often limiting nutrients all around world especially dry regions. Thus Nitrogen is one of the important nutrient for the ecosystem. [1]

3. Lichen often has extremely slow growth rate of less than a millimeter per year. Different lichen species have been measured to grow as slowly as 0.5 mm per year and as fast as 50 centimeters per year [2]

4. Distinct physical mechanisms by which lichens break down the raw stone, recent studies indicate lichens attack stone chemically, entering newly chelated minerals into the ecology. [3]

Methods

Method1 : Liquid emulsion

With a liquid silver emulsion applications can be made to a variety of surfaces such as tile, glass, pottery, wood, canvas, stainless steel and coated metals. Brushing, dipping, and spraying are among the techniques employed for applying the emulsion to three-dimensional surfaces.

Method2 : Transfer gel medium

We have a ton of slab stone in our yard, and as soon as I came across a few pieces that were particularly thin I knew exactly what I wanted to do with them. I also have a few pictures I have been meaning to display, so this project was a good way to finally get around to displaying them. After a lot of research I found that there are many ways get pictures onto stone, each with varying effects. I tried out three methods and eventually went with one though I will talk about the the other two as well.

How to make it?

Here is a breakdown of how I transferred the images. 1. Clean the rock 2. Gesso is not necessary for the transfer here, it just adds tooth and depth. You can use watered down white paint. Let it dry. 3. Use a "Splendid Blender" pen by Chartpak. Other blender pens don't have the same chemical composition, and won't work. Check out "Splendid Transfer" on my sidebar for more info on the pen. 4. Make a laser, toner based copy of the image you want to use. Ink jet copies don't work. 5. Place the copy face down on the rock. 6. Rub the pen over the image, while keeping the paper stable. If it slides around, you'll get a blurry image. Press hard till the image transfers. 7. Make sure you have lots of ventilation when using the pen.
