The glass drops with extraordinary strength became widely known in the enlightened Europe in 1625, when Prince Rupert Padaltsky showed them to the king of England. The latter was so impressed with the strength of glass droplets, which sent them to the Academy of Sciences to study.
Meanwhile, the prince of time was not lost, he didn’t have any time on the wave of the Royal High, declared himself the owner of the mystery of the tempered glass and sold unusual drops to everyone for quite decent money.
The famous English aristocrats so much like to break through the droplets of their long tails, that they were ready to pay well for this pleasure. Evil languages of that time said that the prince raised a very indecent amount of dennaunations on the sale of souvenir products.
In fact, it does not matter.
Another important is — over time, the secret of receiving the droplets of Prince Ruperta (Batavo flasks, Bataves, Bologna flasks) has become known to everyone. It is necessary to drop in very cold water molten glass.
But, after playing, they somehow forgot about them.
They remembered relatively recently and rushed. Literally for three to five years, they covered the number of myths and delusions that even somehow becomes inconvenient.
Therefore, let’s talk today about the 5 most common myths, from which you want to laugh and cry at the same time:
You can beat the hammer, shoot from the gun, to put pressure on the press and nothing will be.
Nuuuu, as if possible, only they scatter.
Small drops of Prince Rupert on average withstand the load of about 6 tons. When they squeeze them with a decadeththrough press, there are quite good such dents of a depth of 3-4 millimeters on a metal plate-foundation. But no drop will endure such a load.
These funny windows do not like rapid focused loads. They can be soldered with a hammer. Yes, it is pretty hard to do, you have to be drumged down with a bogatyr swing, but two men’s hands, an anvil and a hammer make your business — no drop has survived.
This is a very common myth, which is excited, with a breather, many bloggers speak. The fact is that the Batavales … break yes as yet.
Stressful from the inside structure is difficult to be in constant condition — nature does not tolerate the voltage — drops are often exploded by themselves. While we were taken a few drops for a master class out of 21 pieces voluntarily, two were voluntarily.
Drops of Prince Rupert are small glass drops.
In fact, they can be practically anywhere in size. Those small «housing», which can be obtained at home, as a rule, are of size 2-4 centimeters without a tail.
The biggest drop that I had to see weighed 2.4 kg and reached 37 centimeters with a tail. Moreover, the more drop in its sizes, the greater the pressure it can withstand, but it will still break away from strong and sharp blows.
You need to melt the glass and drop into the water.
Well, well, well!
In fact, not any glass is suitable for the manufacture of Batava racials. In addition, much depends on which fluid will fall future drops. The fact is that in the water, the drops of Prince Rupert are obtained only from the particularly durable borosilicate glass. And then far from each drop acquires the necessary strength characteristics — only every 5-7, and sometimes the tenth drop becomes in the middle of the battal cloth.
Of the simple glass, even from the window, drops are obtained only if instead of water as an oil for sharp cooling is used.
Air bubbles will always be inside the drops.
And secondly, the bubbles are sealed in a drop, in fact, not at all is not air — it is a purest, 100% vacuum, which is formed when the glass mass expansion. And the air there simply can not be. Generally! (I wanted to write a beaten phrase «from the word at all,» but I will teach from a bad habit)
What else can be said about these wonderful drops?
Probably everything. Prince Rupert Well done!
