Ken Farrar

Ken Farrar is a long time resident of Kamloops, British Columbia. Ken began sketching
and painting at an early age. His formal education concluded with a four year graduation
from the Alberta College of Art, Calgary in 1972.  After graduating he honed his skills as
a commercial artist, a discipline reflected in his variety of media, techniques and subjects.
Ken was also employed for several years as an artist at the Edmonton Alberta Provincial
Museum.  His artistic accomplishments in oil and acrylic are presently being recognized in
Kamloops and across British Columbia. The subjects of his painting vary  from wildlife to
the local landscapes that beckon at his door.

Glow in the dark powders contain phosphors. A phosphor is a substance that radiates visible light after being excited. Glow in the dark powders have three separate characteristics. The type of energy required to energize them, the color of the visible light they produce, and their persistence of glow, also know as the length of time the glow in the dark powder will glow in the dark. Two phosphors that have these characteristic are zinc sulfide and strontium aluminate which is the newer phosphor with a very long persistence. .

Glow in the dark objects are photoluminescent-they are energized by light.
Phosphorescent powders continue to glow after the energizing light is removed.  Phosphorescent powders have electrons that are easily excited to higher energy levels when they absorb light. The electrons in phosphorescent materials drop to a lower but still excited intermediate level and stay there for a period of time about 6 to 12 hours depending on the color

These powders are easily mixed with acrylic paint but it has taken over a year of experimentation to find the right combinations and procedures

These materials have been around for about 30 years and are still activated by light energy. They can be recharged millions of times and are completely compatible with acrylic paint so they are predicted to last hundreds of years
