This time of year, growers’ attention is focused on greenhouse glazing and seedlings. This is where greenhouse glass can have a huge impact on the growth of these plants. These thoughts also remind us of all the work that needs to be done, even if it hasn't happened yet.

The greenhouse glass should be cleaned, perhaps using a jet washer, which may result in some cracked or broken glass.

Now is the time to sort out all of the greenhouse glass you currently have in storage. But we need to be careful with tempered glass as you can't cut it and it will ruin your knives, some of them are marked (see picture) but since building regulations now insist on using tempered glass in and around doors, or low height than 1 meter, so some are not longer and easier to identify.

Next we start the preparation work for glass cutting.

Safety, before you begin, make sure you are wearing gloves designed for handling glass. Not only is greenhouse glass extremely sharp, it's also slippery. You don’t want to lose it because your hands slip.

method, the first thing you need to do is find a large flat surface to work on. It doesn't have to be fancy, but it does need to be large enough so that you can fit the pane you want to cut down, with a few inches of empty space on the left and right. This way you have room to cut, and if the glass pane moves at any time, it won't hurt you by tilting to one side or the other. While you won't be applying a lot of pressure, you will be pressing down slightly, and you don't want the glass to move away from the surface as you do this.

If you are dealing with large items, then you will need to use a frame designed specifically for this purpose. The frame holds the greenhouse glass in place and allows you to set the cutting blade in a fixed position. You then simply slide it along the surface to score it.

If you're not using a frame, find a straight edge that won't move. Some people use another piece of glass. They simply place one piece of paper on top of another. Whichever method you use, make sure it's straight. Once you scratch the glass, it's too late to make changes.

Now it's time to break the glass. Hold the cutting blade against a straight edge and drag it steadily and firmly from the top to the bottom of the paper. You can tell if you are doing it correctly by the sound it makes. It's like tearing open a carefully folded piece of paper. You can also feel separation happening.

The next step will depend on the size of the piece you want to cut. If it's a few inches, you should be able to snap it off in one step. To do this, place the score line flush with the edge of the cutting surface. Grasp the middle part of the glass you want to break and gently push it down. This is why those who want to burglarize homes will never be able to cut glass like you see in the movies. There's no way they can tilt the glass enough to break it as cleanly as you think.

If the section you are cutting is very narrow, gently tap the back of the score line with the screwdriver handle. If you look closely you will be able to see tiny cracks forming along the lines. To break the workpiece, use one of the slots in the cutting tool. One should be smaller than the other. Use the one closest to the thickness of the glass you want to cut.

This is another reason why the villains can't cut the windowpane the way it appears. They can't push one side in without pushing all the other sides in; pulling the glass won't work either because a) there's no nick on the other side and b) they can't tap the glass from the inside to create tiny cracks, thus This is more likely to happen.

The above is all the work of glass cutting. But here I would like to remind all growers that horticultural glass is currently easily available on the market. Builders, garden centers and glaziers will all have it and will cut it for you if you need a non-standard size.
