Charlie, It seems to me that you will eventually be limited by the metallurgy of the fusible element. Most fuses are made of NiCr wire or other alloy with nickel content. NiCr does have a melting point near 1400 C, but I've never run across a thermal fuse that goes beyond 200-250 C. I suppose you could try constructing your own, but there are several problems. It would be non-certified, and very difficult to control the melting temperature with any precision, since most thermal fuses open based on the combination of current and temperature. If you decide to try this, https://www.goodfellow.com/ is a possible source for exotic wire types, and they have a nice search tool as well.
