I think I've invented a new material. I'm going to call it 'Swisscheesium'.
Next challenge is to find a use for it.
It would be perfect to use to make a replacement part for a Chinese machine.
Its been awhile since I had access to a foundry, but may build one. Actually 2nd one. First one was coal fired (I was in OK lots of free high sulfur coal) if there is a next one it will be fueled by natural gas.
As you have asked it sounds like its too rich. You'll just have to experiment to find the correct adjustment.
For a thermometer I used a 2000 degree F meter with a thermocouple on it and inserted it in the melt. I took a look at a couple of suppliers I've used and came up empty. In any case I suspect my predecessor cobbed it together as was his tendency. However it always worked.
