HOW TO CUT GLASS WITH A WIRE

Using wire to cut glass without a glass cutter is also easy.

The "hot wire" method of cutting glass uses a piece of nichrome wire to make a narrow thermal stress line on the glass causing it to crack in a desired spot. For example if you wanted to cut the top off a bottle you would wrap the nichrome wire around the top and apply current to it until it glows red. It would probably work best if you first score the bottle with a glass cutter.

Nichrome Wire (NiCr, nickel-chrome, chrome-nickel, etc.) generally refers to any alloy of nickel, chromium, and often iron and/or other elements or substances.

Nichrome alloys are typically used in resistance wire. They are also used in some dental restorations (fillings) and in other applications.

When starting the cut it is important to apply a good amount of pressure.

In order for the vessel to burst evenly, it is necessary to monitor the density of the attachment of the wire to the walls of the vessel (avoid sagging).
