Glaze Capsule?

Don't know where they drop, but I want to know how they work. They are used for elemental attacks, correct?
And how many times do you have to use the elemental attack before it goes away, if any?

capsules are just like bullets except that they are only used up when u do elemental attacks and they only hold 1000 shots per capsule

each time u use ice splitter/flamethrower, 1 shot is deducted from the 1000 shots in the glaze/blaze capsule until it reaches 0, after that when u use ice splitter/flamethrower 1 bullet is deducted from ur regular bullets and ice splitter/flamethrower does 50% of its regular damage.

capsules are rechargeable just like bullets also.
