-About "Ask A Scientist!" -
On September 17th, 1998 the Ithaca Journal ran its first "Ask A Scientist!"
article in which Professor Neil Ashcroft , who was then the director of
CCMR, answered the question "What is Jupiter made of?" Since then, we have
received over 1,000 questions from students and adults from all over the
world. Select questions are answered weekly and published in the Ithaca
Journal and on our web site. "Ask A Scientist!" reaches more than 21,000
Central New York residents through the Ithaca Journal and countless others
around the world throught the "Ask a Scientist!" web site.
Across disciplines and across the state, from Nobel Prize winning scientist
David Lee to notable science education advocate Bill Nye, researchers and
scientists have been called on to respond to these questions. For more than
seven years, kids - and a few adults - have been submitting their queries
to find out the answer to life's everyday questions.

Inks are colored liquids that are used to write or print onto surfaces
(paper, plastic, metal, glass, etc.) or objects such as boxes and bottles.
They have been used as long as people have been writing and drawing. They
may be white, black or any of the colors of the rainbow. Inks are used in
ballpoint pens, computer printers and huge printing presses that print

*Ink* is a liquid or paste that contains pigments or dyes and is used to
color a surface to produce an image, text, or design. Ink is used for
drawing or writing with a pen, brush, or quill. Thicker inks, in paste
form, are used extensively in letterpress and lithographic printing.
Ink can be a complex medium, composed of solvents, pigments, dyes, resins,
lubricants, solubilizers, surfactants, particulate matter, fluorescers, and
other materials. The components of inks serve many purposes; the inkâs
carrier, colorants, and other additives flow and thickness of the ink and
its appearance when dry.

· Carrier substances
Inks generally fall into four classes:^
Pigment inks are used more frequently than dyes because they are more
color-fast, but they are also more expensive, less consistent in color, and
have less of a color range than dyes.^

Pigments are solid, opaque particles suspended in ink to provide color.^
Pigment molecules typically link together in crystalline structures that
