Is it true that the crack in the glass can «overgrow»?


The glass is associated with a huge number of myths.

And one of them — over time, the cut from glass cutter or even a simple crack can «infect».

In stitches for stained-glass windows, in videos on YouTube, it is often said that after cutting glass cutter, glass should be broken as quickly as possible. Otherwise, the crack is collapsed and smoothly break the glass will not succeed. That is why, they say, professional glass cutters fill with oil specifically so that the oil penetrates into the crack and does not allow the glass to «overgrow».

Today we had a chance to check this statement. I helped the neighbor to disassemble the old glass greenhouse, which was built back in 2002 (the house was built in 1992, and the greenhouse in 2002 so selected, not 20 years, and 18 it turns out).

When disassembling the greenhouse on the same glass, I saw a rather clear track from the glass cutter. Sin was not to take advantage of the chance.

Neatly reset the glass from the frame …

Brought to the workshop …


took a leap for glass

Slightly pressed and …

Dzynk — Glass broke into two parts as if he had just cut the glass cutter.

For the sake of interest looked at the rift closer. It is perfect that the glass cutter cut through no more than 0.7 millimeters of glass.

After that, they took professional oil glass cutter, cut the line and also broke.

No difference!

No any. It is simply not. Therefore, the glass over time does not overgrow, does not collapse … as a crack was, so it will remain.

Now let’s talk about why professional glass cutters fill with oil or a special glass cutting fluid. After all, many Master are confident that the oil facilitates the process of flushing the glass.

Nothing like this!

Here on self-segment everything is very simple — the main purpose of the oil is to protect the cutting steel roller from overheating.

If you use glass cutter without oil (or a special cooling fluid), the roller will quickly fill and instead of fast cutting glass will be one torment.

The manufacturers themselves themselves indicate that without the use of oil, the service life of the glass cutter is reduced by 5 times!

In addition, in the process of cutting, the oil binds glass fragments and dust, which is flying out of the cutting roller, and does not allow this garbage to get into the lungs.

As is known, glass dust is not excreted from the lungs, and the silicosis is one of the most common diseases among glasswalls. That is why oil glass cutter is a mandatory masters attribute.
