pencil monument

pencil monument

This tower was known as the pencil monument because of its resemblance. But in fact it was built to commemorates the Battle of Largs, where the Scots defeated the invading Viking fleet in the year 1263. The monument was constructed in 1912 at  Largs, Scotland.  : www.scottishaccomodationindex.com/largspic.htm

Pencil Lengthener

Pencil lengthener is something that let you attach to the back of your pencil when it been overly shorten. Sometims a pencil cap could doubles up as a pencil lengthener

Pencil poem

February 18, 2009

IN THE DESK DRAWER

Number two pencils,
cedar-fresh, new, neat
in sunny yellow rows:
Dixon, Eagle, Ticonderoga,
conforming comfortably
to each other in the pencil-box.
A wooden-handled steel-nibbed pen threatens;
a clean-pink eraser reassures;
a metal-edged ruler regulates.
But the pencils,
sharpened, competent, obedient,
lie alert and still–
ready to do my will.

LATER

Old pencils,
round-tipped and stubby,
paint bitten and chipped,
erasers slick, flat,
black from drudger,
clutter the drawer.

They might come in handy some day.

Pencil hardness test

Usually the coating thickness being tested is 1.0-1.5 mils (a mil is one millionth of an inch) and has been allowed to dry for 7 days. In some cases, a different drying schedule is used, and the chart indicates those in brackets. The ambient temperature during the test can also be a factor in the drying times and can have an effect on the coating’s hardness.

Select a pencil from your set and make a line about 1/2-inch long. If the pencil you start with scratches the surface of the coating, then go down the pencil grades until you come to the first pencil that doesn’t scratch the coating. Redo the test, and if you get the same results, you have determined the ‘Pencil Hardness’ of the coating you are testing. It’s that simple. There are some coatings so hard that the 9H pencil won’t scratch them-all of these coatings get a 9H rating to designate their hardness.

Use this chart only as a guide. It is also important to understand that the degree of hardness of any generic coating may not always be the same; in other words, if one company has a polyurethane with a 3H hardness, do not assume that every other polyurethance will have a 3H hardness. They won’t; they will vary from manufacturer to manufacturer, and from product to product.

As I mentioned previously, the pencil hardness test is only one of many tests that are done to evaluate a coating’s performance. Other tests are abrasion, reverse impact resistance, direct impact resistance, cross-hatch adhesion, oxidation, gloss retention, UV resistance, yellowing, blistering, drying times, chemical/solvent resistance (using both the rubbing and spot/time tests), salt spray resistance, humidity resistance, acid and caustic resistance, the VOC and HAP contents, and so on.

All this information is helpful in choosing or evaluating a finish. But regardless of a finish’s rating, the best advice is always: ‘handle with care’.

Pencils hardness

February 18, 2009

Have you wonder what the H and B stands for on a pencil? The ‘H’ stands for hardness, the ‘B’ stands for blackness, and HB is for hard and black pencils. The hardest is a 9H, followed by 8H, 7H, 6H, 5H, 4H, 3H, 2H, and H. F is the middle of the hardness scale; then comes HB, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, and 9B, which is the softest. Another grading method uses numbers; the equivalents would be #1=B, #2=HB, #2-1/2=F, #3=H, and #4=2H. The most commonly used writing pencil is the #2 (HB grade), which is fairly soft, contains more graphite, and leaves a dark mark.
