here is how it works. use distilled water only. obtain a brown glass bottle of exactly 100ml. place the entire contents of the 100g container into the brown bottle. notice that this amount fills the bottle to more than half way. add distilled water until it covers the crystals a bit. put the cap on and shake. the bottle will get extremely cold, same principle as using salt to make ice cream. notice how much has dissolved. it will now take a full bottle to dissolve all of it. do this by adding a little water at a time and shake it and leave it for hours and do it again. there is sort of a jump in volume at the end which is why i dont fill it to the top right away. when you reach the top the last crystals should disappear. it they disappear before that then stop. you have a saturated solution. an average dropper will deliver 30mg. with one gram per ml it is easy to count the drops to make an ml and then divide into 1000.
