Yes You can reuse solder paste, you simply don't put pback the use solder paste and the new one in the same jar, you don't refrigerate the old solder paste again. And before you begin to use the old solder paste be sure to mix it well. Good luck

Thanks for you reply CL. For Q2, I want to know that is there are any ratio of mixing new or old soldering paste? Also, can we put the "working jar" and opened unused solder paste to refrigator and soft it by solder paste softer in next time of prod
