Do you know the difference between a Squid, an octopus and a starfish? Well, listen to this week’s episode, and special guest Troy Hughes explains … well, you still won’t know. Another week passes and Jeff forgets to tell his tale of the day he met 4 Mitt Romney’s at the 2002 Olympics.
Michelle Bachmann cuts the last thread holding her to reality. The California Supreme Court opens the season against folks in the LGBT community again. Newt Gingrich is a dirty, dirty old man. Republicans are now the best liars on the InterWebTubes … total GOP domination. Rick Perry is an idiot, some more …

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 newspapers and magazines.
The most important part of an ink is the dye or pigment that gives the ink its color. Dyes are colored materials that completely dissolve in the ink (like sugar in water). Pigments are small particles of colored materials that are suspended in the ink (like fine sand in water). Pigments need to be ground to very small size so that they will not settle out of the ink. Dyes and pigments can be obtained from natural plants and minerals or can be manufactured from other chemicals.
Inks also contain a liquid or solvent that dissolves or suspends the dye or pigment. Many inks are largely water, but liquids other than water such as alcohols and oils can be used. Inks may also contain other things like resins and polymers (big molecules), stabilizers for suspended pigments, preservatives, etc. depending on how the ink will be used. Designing an ink that works well can be a very complicated job.
Making inks is simple. In a big pot, all of the components of the ink (dye or pigment, liquid, etc.) are mixed very well, sometimes with heating. Good mixing is important so that all of the ink in a batch is exactly the same. The ink may be filtered to remove any big particles and then it is ready to be used. Ink makers test their inks to make sure they are the right color and work well and then package them in large bottles or load them directly into pens or printer cartridges.
The end result is a much more colorful and informative world. Just think of all of the books, magazines, cereal boxes, soda bottles, etc. that you see and use every day!
