If you're ditching the borax then you need to use another method of keeping that melt easy. Heat helps but if the borax goes, then add more heat. Sodium nitrate would be where I would look for chemical help. . Lithium could be increased but it's pricey.
My original phosphate melts needed 2450F and very small charges. That was 1975.
