How Long Does a Glass Nail File Last?
In order to explain what is the lifespan of a glass nail file, we will have to go back in time to primary school. Do you remember how to determine which one of the two objects is harder? Common sense suggests that when you are able to scratch one object with another the one in which the groove remains is the softer one. So the glass nail file needs to be harder and the nail softer. Well, how does that relate to longevity?
In 1812, the German mineralogist Friedrich Mohs compiled a table of materials and numbered them according to hardness. From the softest to the hardest. The nail is marked with the number 1 on the scale and the glass has the number 5. The glass is naturally harder than the nail by a full 4 orders of magnitude. It is no coincidence that I put butter and steel on the table as well. Like the fingernail and the glass, they are 4 orders of magnitude apart. The answer to the question: “How long does a glass nail file last?”, Or how long it takes for a glass nail file to become dull is directly offered here.
| Butter | 0.5 |
| Nail | 1 |
| Knife | 4.5 |
| Glass | 5 |
| Diamond | 10 |
The glass nail file dulls as fast as a butter knife.
The glass nail file is as sharp as a knife. The sanding surface is produced by etching the glass itself. In the glass, the acid creates small dimples with sharp edges that gently and efficiently saw. If the glass nail file from us stopped sawing, it is not that it has become dull. You also need to take care of the file, so I will refer you to the article: “How to clean a glass nail file?“.
Beware of imitations! Not all that glitters is gold!
There is a lot of different glass nail files on market and not every manufacturer makes a good name for them. Glass nail files, especially from Chinese production, use a different manufacturing technology. They bomb the glass with sand, thus breaking the surface of the glass. The result looks the same at first glance, but when magnified several times, a marked difference can be seen. No dimples, no sharp edges. Such a file is blunt from the factory!
Others stick abrasive particles on glass nail files. They are basically paper nail files based on a glass core. They have a shelf life because the particles fall off during use. They are coarser and generally do not provide the comfort of our etched ones.
