What do I do with burnt incense at home?

I have been making incense offerings to my small Buddha statue at home. But after a while, the ashes from the incense has piled up and is going to overflow my incense pot soon. What should I do with the ashes from the burnt incense?

hi @kangsheng
I am not sure about what to do with the ashes also.
I use a electric light at home.

The discussion here may help provide some suggestions:
