Glass beads were used in the cellular respiration experiment as a control to ensure that any changes observed were due to the presence of living organisms (yeast) and not simply the physical presence of an object in the test tube. The glass beads did not respire, so any changes in gas production or respiration rate observed in the experimental group could be attributed to the yeast cells metabolizing the sugar.
There are many ways to tell glass from semi precious stone beads. EHow has published an article on how to tell glass from semi precious stone beads, which describes how to inspect the sound, texture, bead, and cut of the specimen.
Glass beads are used in a fractionating column to provide surface area for vapor-liquid contact and enhance the separation of components in a mixture. The beads help in achieving more efficient distillation by increasing the number of theoretical plates, which improves the separation efficiency of the column.
To find the weight of the same number of marbles as the glass beads, we first need to find the weight of one glass bead in grams (320 mg = 0.32 g). Then we divide the total weight of the glass beads by the weight of one glass bead to determine the number of glass beads. Finally, we multiply this number by the weight of one marble (8.58 g) to find the total weight of the marbles. In this case, the same number of marbles would weigh 0.32 * 5.13 kg / 8.58 g each = 1.92 kg.
You can use 2-4 mm glass beads for a Vigreux fractionating column of that size. To prevent them from falling into the flask, place a layer of glass wool at the bottom of the column to act as a barrier. Additionally, you can use a fritted disc or a glass bead support to hold the beads in place.

Lampwork glass beads are often used to make jewelry. Some examples of this jewelry can be found online at Lampwork-Beads-Glass, Zacoo, and Lima Beads.
The most sustainable beads are pearl beads. They are much stronger and last much longer than glass beads. This is one of the reasons they cost more than glass beads.

YES! Because when you heat the mixture of water and glass beads up at boiling temperature, the water will evaporate and leave the glass beads behind. =-)
Crystal beads are made from leaded glass, giving them a higher refractive index and more sparkle than regular glass beads. Glass beads are made from silica, soda, and lime, and are generally less expensive than crystal beads. Crystal beads are often used for high-end jewelry designs due to their superior quality and appearance.

Technically there are only one type of glass beads. The reasoning behind this is because there is only one type of glass, which would actually just be glass.
about 15 beads an ounce
No, they are not.
cut holes slightly larger than the small beads in a cloth and pour the mixture through
