When printing pictures, the shiny side is usually the top side because it typically has a coating that enhances image quality and color vibrancy. The dull side is typically the bottom side where the ink is absorbed.
The shiny side of aluminum foil should be facing outwards for better heat reflection.
The shiny side of aluminum foil reflects heat better than the dull side.
When cooking with foil, use the shiny side facing out to reflect heat and the dull side facing in to absorb heat.
Aluminum foil is shiny on one side because of the manufacturing process. During manufacturing, the foil is rolled to make it thinner, which creates a shiny side. The dull side is created by the contact between the foil and the rolling machinery.
On Reynolds aluminum company website you'll find :Which side of Reynolds Wrap® Aluminum Foil should I use, the shiny or the dull side?Actually, it makes no difference which side of the aluminum foil you useboth sides do the same fine job of cooking, freezing and storing food. The difference in appearance between dull and shiny is due to the foil manufacturing process. In the final rolling step, two layers of foil are passed through the rolling mill at the same time. The side coming in contact with the mill's highly polished steel rollers becomes shiny. The other side, not coming in contact with the heavy rollers, comes out with a dull or matte finish.
the right side
If you are baking something wrapped in foil, you should probably have the dull side of the foil out. The dull side reflects heat a bit less than the shiny side. This means that cooking with the shiny side out would make your food cook more slowly.
The shiny side of aluminum foil should be facing outwards for better heat reflection.
It is a result of the rolling process, manufacturers roll a large ingot of aluminum through successivly smaller thickness of roller so the ingot gets thinner and thiner, however for the very last roll the aluminum is to thin to be rolled alone, so they put through two sheets, the sides which face each other become dull.
You should use tin foil with the shiny side facing inwards towards the food and the dull side facing outwards when cooking with fire. This can help reflect heat away from the food and prevent the foil from burning.
The "inside" of tin foil is the dull side. The "outside" of tin foil is the shiny side.
The shiny side of aluminum foil reflects heat better than the dull side.
The shiny side of aluminum foil reflects heat better, while the dull side absorbs heat more effectively. However, the difference in heat conduction between the two sides is minimal. In practical use, either side can be used for wrapping items, but for keeping food warm, the shiny side is often recommended to face outward.
When cooking with foil, use the shiny side facing out to reflect heat and the dull side facing in to absorb heat.
Generally speaking, the shiny side of a DVD (or CD) is, indeed, the content side, so yes, this is true. It is possible to put a finish on the "label" side of a DVD or CD that is more shiny than the "content" side, but we often see a "dull" finish to the non-content side of one of these discs. If you look at the content side of the media in light, you should see a bit of a "rainbow" effect as light is reflected off the reflective surface beneath the clear material the disc is made of. This is the content side of the disc, and the laser used to scan it will "bounce" off the reflective surface.

Shiny side up. The reflective surface is designed that way to deflect radiation better. But, babies won't die if you do it the other way around.AnswerTake it from the people at Reynolds. They make the stuff. They will tell you that it makes no difference which side is in or out. Optical light scatters differently from the dull side than from the shiny side, which is more like a mirror. But both sides absorb or reflect light (and infrared radiation) equally. AnswerScientifically speaking, the shiny side is better top be towards your food when cooking--the reflective surface makes for slightly faster cooking. The dull side should be towards the food when freezing--the shiny side outwards will keep any heat that would enter at bay better.These make very small differences, however, and your food will probably come out APPROXIMATELY the same either way.
