my fire extinguisher says full but i tried it out since ive never used it just to see how it works. Now it says its empty, even though i can feel it has some gas in it, should i discard it and get a new one or is it still ok to use in case of a real fire?
Nor will you now. If the releasing agent failed then the plastic resin are bonded now forever. Try again try a new casting medium like plaster, cley etc.
