GVG ceramic foam filter replacement

[crasse]

Hi guys ! new here (obviously) but not with dmt

Currently my GVG ceramic foam filter (the black cylinder that looks like a solid sponge) is obstructed as I never changed it yet after a lot of use.
However I got some difficulties finding the right material in a decent quantities.
If i'm not wrong it's this kind of thing :

Ceramic foam filters | Gasser GmbH Foundry Technology

Foam ceramic filters for max. casting temperatures up to 1450°C in various sizes, thicknesses and materials.

gasser-gmbh.at

but I can't find this thing in decent quantites (only in industrial quantities) as I only need a few grams of it...

Does someone know a place to find some, or an equivalent as replacement material that I can find easily in shops ?

Hi there!

Do you have any idea what it's obstructed with? Have you tried any methods of sorting it out? Have you only ever used it with freebase DMT? What kind of lighter have you been using?

I can suggest several ways in which it might be obstructed, and what might help in some of these cases. One thing to be wary of is, if any ash has made its way into the filter, that can react with the ceramic to form a glassy layer which builds up over time. That is to say, roasting an ash-clogged ceramic filter may do more harm than good.

Hi ! thanks for help,

yeah I only use the GVG with freebase DMT, I didn't tried anything to clean it yet.
I'm using a tempest lighter (strong straight blue flame).
I would say that yes I got a glassy layer of something on and in the filter (here is some pics of it)
