Great build quality, easy to use, and excellent value
I’ve been using this Kanthal wire for kiln support on kiln cookies, and it’s been fantastic. The build quality is solid and withstands multiple firings at Cone 10 without any issues. The wire is easy to cut and shape, making it simple to create custom supports for my glazed pieces. The functionality is perfect for preventing glazed bottoms from sticking, something I struggled with when using stilts, which would leave marks on my mugs. For the price, it’s excellent value. Durable, reliable, and incredibly easy to use, this wire has saved several pieces, and I highly recommend it for any potter looking for a budget-friendly, effective solution.

Good product.
I use this wire for coil building. It works great for me. I've bought this brand a few times. The wire is always clean with no kinks. I use "Master wire supply" stainless 316L and kanthal. I have been very happy with the quality.

Excellent for vaping
I don’t usually write reviews but I had to for this one. I’ve been building my own coils for a while to save money. I’ve never used such a high quality wire. It’s easy to wrap and the 100 ft should last me at least a two years.

Tough enough
I purchased this wire to wire things together. It works well because it's not to heavy but is just heavy enough. For things like picture frames it is great! It can wire flowers together as well. I would recommend it.

Works for electronic projects
I used this wire as a resistor for an electric project. I made a coil and soldered it onto the ends of a speed controller and when I applied power, the wire lit up nicely. One thing to note is that I couldn't tin the wires properly, so I had to melt some solder and jam the wire in.
