Why does grease turn paper clear?
818456
paper is pulpified wood that's dried into thin sheets.  Any liquids (grease, water, etc) will soak into the mix and separate the fibers, causing it to become transparent.  Except with water, it will ultimately evaporate out.  Grease doesn't evaporate away at room temperature like water does, so the transparency remains.

look into the dimaso variable in the help files, if you change that it I bet it clears up.

the wiping action of the dry cloth might generate static electricity, which makes the mirror attract lint/fibre...so it looks dusty after wiping!

Is the paper or the cover oil stained?\n\nEither way:\nMake a mixture of 500 gr. Of soap, 300 gr. Of clay, 60 gr. \nOf quick-lime, and sufficient water to make it of the right consistency, spread a thin layer of this on the stain, and leave it there about a quarter of an hour.  Then dip the sheet in a bath of hot water; take it out, and let it dry \nslowly.\n\nIt'll be more difficult if the oil is on a book page but not impossible. I would also recommend caution-just use a small corner of the cover/page with the method first to make sure you won't be doing more damage.

your ovalating! it like clear mucousy stuff that come out but after it dries it becomes white.

There are two primary advantages to fluted filter paper.  One is the increase in filter area.  The second, and probably the more effective of the two, is the fluting creates gaps between the filter paper and the funnel in which it is resting.  These gaps provide channels for the solvent to flow through after it passes through the filter paper, thus greatly increasing the speed of solvent flow through the paper.  This effect is most noticible with the finer filter papers.

If you have a monitor connected to your computer - which most people will else it is kind of hard to find out what's going on - then you'll know grease and dirt are all too easy to get on the screen.\n\nSo what can be done about it? Well, use a lint free cloth that is very slightly dampened with water (note not wet)\n\nThe problem is that many cleaners will actually damage the monitor and make it worse, so therefore always keep cleaning very soft and simple with a monitor.

There is a free to use software named EasyCleaner. You can find it at http://www.toniarts.com It will solve this and many more problems of yours.\n\nBest of Luck!

it sticks to finger oils/grease. if you put some on a finger, and touch it to another, instant, permanent bond.

Or if you haven't printed in color for a while, the nozzles (or whatever) may have dried out.  Try running the "cleaning" routine on your printer -- usually available by right-clicking on the printer and selecting 'Properties'.

When our good white paper is prepared it is bleached.This removes all colour from it or chemically the present oxygen.But after a long period of time after this paper is exposed to air,the oxygen molecules are regained and the old colour comes back.\n\nThis is because generally CaOCl2 (bleaching powder) or SO2 is used.When a stronger bleacher is used the regaining of colour wont happen.

You can get putty like ones from art shops that remove dark HB and pretty much destroy anything apart from the pressure on the paper. they need to be cleaned a lot but can be molded to an easy shape and are dabbed rather than rubbed which means less white flakes and little paper ripping.

one of your solvents is more polar than the other (in this case acetone) the substances to be separated by chromatography will move the most in a solvent mixture they are most similar to. Remember like dissolves like. So if your unknown is easily dissolved in a non-polar solvent like hexanes then a non polar solvent will move it the most on the paper. If your substance is very polar, IE. an organic acid. It will stay near the bottom of your chromatography paper, when using a non-polar solvent mixture. 9:1 ether:acetone is actually quite non-polar, you can progressively increase your solvent polarity by making multiple solvent mixtures with changing ratios 8:1, 5:1 etc.   Obviously, you must use a new piece of chromatography paper each time you run a new experiment (unless your spots didn't move at all!). The basic concept of these experiments is polarity and how it relates to separating a mixture. Remember, like dissolves like!

Don't know the specifics of the "spy kit", so I can only guess that the invisible ink you're using is water-soluble.  If so, and the paper has gotten wet, then the ink has bled (wicked) out over the paper, and there is no way to return it to its original state.\n\nOh, sorry about that, Chief. (Do you remember "Get Smart"?)
