Craft project ideas for kids have been around for as long I can remember - and believe me, most of it has probably involved hot-melt plastic in some form since the 1970s (massively embellishing here). If this seems a bit much at first, Do not to worry! Below are simple steps we can follow to break it down. Introduction to this Amazing World of Learning!
The difficulty level of getting your fuse bead samples ready for XRF analysis similarly is not all that high. The XRF analysis (X-ray fluorescence analysis) is the method how we discover which elements are in a sample. Examples are study of this nature, usually performed on fuse bead samples because the results deliver greater precision. How to Make Your Fuse Bead Samples
1 : Get your samples in a row Like I mentioned, you need to collect.... A sample could be a rock, or it might even metal or soil. It is essential to obtain a sample that authentically reflects the population child-care you want to examine. For instance, if you wish to know exactly what a sort of rock is constructed with be sure whatever example collected stands for that kind. This way, you will get the good results!
Crush your samples If you have collected a sample, the next step is to crush it into further fine powders. It is very crucial since the powder has to be small, so that it can mix with other materials properly. A mortar and pestle, which is a heavy material tool for grinding things down, or you can also use an instrument called jaw crusher so that the job does not need to be done by hand.
Mix your samples: After crushing, the sample becomes powder and is mixed with something called flux. It is simple: the flux makes your sample to melt uniformly when heating it in a furnace. You will have a choice either to use borate or lithium tetraborate as your flux material. These materials insure your sample is uniformly heated and processed to a glassy bead.
Create your fuse beads: And now to the best part, making those fuse perler beads! Get a small portion of your sample and flux mixture, put it carefully into the crucible. Such crucible can be made from platinum, or for example - nickel that is capable to withstand a high temperature. This mixture will be melted into a glass bead, by heating it in a furnace. This can be a very exciting process to watch!
Examine your fuse beads: Finally, as soon as you have the bead collection prepared to go, they're poised for XRF examination. You will place them in the machine of XRF that reads sample using X-rays. These interact with the material and make it emit a X-ray fluorescence signal. The XRF machine measures this to provide information on the elements found in your samples.
