Something about Colloid Mills and Other Interesting Things

When I was in high school, physics was one of my favorite subjects. Other subjects I enjoyed very much included math and chemistry. I guess when you grow older and get reminded of something you liked in the past, you are happy about it and are willing to learn more about all those things you didn’t have a chance to learn when you were younger.

It is with great joy that I read about colloid mills this morning while eating my delicious breakfast and while looking at the website of What I am going to write today about brings definitely some fond memories from the past from the times when I was younger and reminds me of all those good times I used to have during my physics or chemistry classes.

One of the first things I am going to write about in this post is something called the colloid mill. The colloid mill is a very interesting machine allowing us to reduce the size of a solid particle in liquids. It is widely used in industries such as the cosmetic industry, pharmaceutical industry, or even paper and food industry where the size of droplets needs to be reduced as much as possible to allow for the production of items such as cosmetics, soap, textiles, or even food. I won’t go into details of how the whole process works, but if you would like to learn more about it feel free to visit the website of and learn as much as you want on the topic.

Another interesting piece of equipment used in many laboratories to alter the texture of various substances is something known to the public as the homogenizer. If you have ever played Ultima Online, or if you are generally familiar with the concept of mortar and pestle, you know precisely what I am talking about here. Disruption of the material was used in older technologies, but the modern ones allow for a much wider use of the process. As always, for more information you can go to

There is one more thing I would like to mention in this post. I am thinking here about machines known as hazers. If you have ever been to a concert where hazers were used, then you know what I am talking about here. They are not the same as theatrical machines that are designed to produce fog that obscures the view. Hazers create a type of effect that is very similar to fog machines, but its properties are definitely different. While the fog will always obscure the view, hazers produce an interesting effect in which the performer on stage will not be obscured by it. This is very convenient for those performers who like the idea of being visible even when the hazers are at work as it allows them to be seen by their fans at all times. I can also think of many other situations when hazers can come in handy, but I am not going to mention them in this post due to lack of time and space.
