Create a scratch on the glass wall surface by drawing the corner of a file or tungsten carbide knife perpendicularly across the tube.
Do not saw the glass. Sawing the glass will not make the process of breaking the glass any easier. It is not necessary jow make a long scratch.

Our first lab of the year was over lab procedures, and the first part was to cut an 8" that's 20 cm, Mr. We used 4mm tube, and the scribed line only had to go about an eighth of the way around. Teralab's explanation is exactly how we did it, and I got perfect breaks three out of three times.

If the gap between the teeth is too large, the hacksaw will snag on the pipe. Clamp the copper pipe, if possible. If the pipe is loose, set it in a vise so that the spot you want to cut extends a few inches about 5 cm from the jaws.

Determine where you'd like to make the cut on the copper pipe. Take a fine permanent marker and draw a line where you want the cut. After you've cut the pipe, you can wipe the mark off using rubbing alcohol. Set the hacksaw blade on the mark. Place the teeth of the hacksaw directly on the mark you made.
Hold the handle of the hacksaw with your dominant hand use your other hand to support the top of the saw. Saw firmly into the pipe. Move the blade firmly across the pipe and lift it up as you bring the hacksaw back towards you. Set the blade back into the grove you've begun cutting and continue to push the saw blade into the pipe until the cut piece falls off. Clean the cut copper pipe.
Use a 4-in-1 cleaning tool to clean the cut pipe of any metal debris. Use the ends of the tool to brush inside the end of the pipe and place the center circle of the tool around the pipe itself. Rub the tool around the end so the metal bristles of the tool can brush and clean the pipe. Wrap it around the pipe and vigorously pull both ends of the sandpaper back and forth.
