What filter is this and how do I get it out?

[Blake Chancery]

This is a filter that came with a Peterson System pipe that I bought secondhand as an estate pipe. I need to clean the pipe and want to remove this first. It feels like some sort of stone.

That's likely going to have to be pushed out with a wire.

Do you know what type of filter that is?

I've never used filters myself but I've never seen such a thing.

I have never seen a filter like that. Please take a picture of it and post it once you remove it.

Looks like a Nording keystone.
They're supposed to be placed at the bottom of the bowl to absorb moisture and keep tobacco dry.
That one must have been sucked up ! I can't imagine it being placed there deliberately. But then again, strange things happen ?

Looks like some sort of absorbent stone a previous owner installed. Never seen anything like that
Petersons don't really need them, anyhow.

Tweezers.

The Nording keystones I have are clay & very soft.
This looks like someone stuffed a rock in there, maybe someone's kid playing with it. You could try needle nose pliars and hopefully it will come out easy.

alien egg is my best guess.
