[American Constitutionalist]

Wonder if there is any commercial value of this stuff ?
Tell the environmentalist that it's helping to clean up the environment and at the same time make a profit.
There has got to be some kind of commercial value of this stuff.
Lava Rock ? landscaping material ? heated rock spa material ? crush it up and use it in cement ? mix it in with asphalt, stones and path roads with it.

[Boogieman]

Lots of commercial applications, like lava soap, abrasives, hydroponic medium, aquarium fill.

Of course there is commercial value. What do you think people use to rub dead skin off their heals and bunions. I read where after Mt. Pelee blew its top in 1902, the ask that fell on ships decks was collected and used to sand down the wooden decks and considered a superior abrasive.
