Thunder stone (single use?)

[Elvinis75]

Is the thunderstone a single use item?
It doesn't say that it is used up after going off?

{Sarcasm}Come to think of it, the RAW doesn't explicitly state that a vial of Alchemist's Fire is used up after one use either{/Sarcasm}

Yes, the Thunderstone is used up.
