How do you test Nichrome wire?
Place tip of nichrome wire in flame until there is a constant orange/yellow color. Dip the tip of the nichrome wire into a salt (only put one or two crystals on the tip). Place the tip of the nichrome wire (with salt on it) in the flame. Observe the color of the salt as it burns.
Is Nichrome wire magnetic?
Nichrome is a non-magnetic alloy of nickel and chromium. Nichrome is widely used in heating elements. It is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.
What kind of wire do you use for a foam cutter?

What can a hot wire cutter cut?
Introduction: Hot Wire Foam Cutter Cheap ($30+-) and easy to build hot wire foam cutter made from commonly available parts. Cuts styrofoam for surfboards, model plane wings, sculpture, model train or tabletop wargame terrain, 3D sign letters, mold models for lost foam casting, etc.
At what temperature does foam melt?
464 °F
Is Thermocol dangerous?
It responds very slowly to bacterial decomposition in the soil, thus making the soil infertile. It also releases poisonous gases on burning, which can cause respiratory problems, or even death, when inhaled. Hence thermocol is harmful for the environment.
Can Thermocol reduce heat?
Thermocol or EPS sheets are in fact an excellent thermal insulator for the Indian climate. They are lightweight and affordable (making them easy to install), with a high insulation value. EPS insulation increases the life of the structure as well as making the interiors comfortable.
