## Customer Reviews

### ⭐⭐⭐⭐⭐ Good heater wire
*by B***R on April 19, 2025*

You can make coils of this wire, run electricity though it, and get it to glow yellow-orange hot. However, it has a very low electrical resistance, so you need a low voltage and high current unless you use a very long piece of the wire.

### ⭐⭐⭐⭐⭐ Easy to Use
*by S***P on January 10, 2025*

I make my own ceramic jewelry, and need wire that will withstand the high temperatures inside a kiln. This wire is sturdy, but at this gauge, still flexible enough to bend and cut easily. The only problem I had is that I had to take off the outer plastic ring in order to unwind it, and that caused the whole spool to unravel at once.

### ⭐⭐⭐⭐⭐ Wire
*by S***E on December 8, 2023*

Good wire that stands up to the torch
