Before someone says it, i fully realize that there are all kinds of sources out there for pumice, but im specifically looking for lab grade pumice
that is of quality to be used as a support for a catalyst. If someone has a source for this please let me know...additionally, if someone has obtained
pumice from somewhere that may not be lab grade but that they have had personal experience and success with that would also be very helpful.
