Thank you for your detailed reply Joseph and thank you Vic for your advise.

What if I expand the pumice and then crush it to make bricks? or make bricks of the pumice in its whole form.
Does pumice have the same insulating characteristics as perlite?
If so, could I not use the pumice as part of a mixture to make bricks/hollow blocks?

Side note, from a reliable source I have heard that our pumice is very similar to the american perlite/pumice according to a chemical analysis but the question is how good quality is the american product?...
Which characteristics determine the quality?

Can anyone recommmend an lab that provides good chemical analysis on perlite/pumice and chromite ore (magnetic blacksand)?

Once again thank you for your time everyone.

Kind regards,
Peter

Perhaps you could continue this conversation by private message (PM)? As already mentioned, this is a forum for people who collect and enjoy mineral specimens. It is not a forum for commercial uses of minerals. Now that you have your answer, any further conversations about processing and quality need not be shared with our minerals community. I don't wish to sound mean, but this discussion is outside the scope of FMF.

Thanks,
Tracy

I'm sorry Tracy but I could not PM because I am still in my trial period.
