Brent you're certainly welcome! Glad you were able to find some Gordon's. I heated it to around 725-750 degrees and have read various posts/articles where temps were anywhere from 650-800 degrees, so I'm not sure what the optimum temperature should be. I somewhat split the difference and with judicious monitoring was able to get the "fire blue" I wanted for some pins.
Larry Potterfield mentions in his video on the subject that he heats his salts to 650 degrees. It sounds as though you've found your answer.....good deal and have fun!
