How to wash pumice and be a good neighbor?
« on: September 14, 2012, 02:03 PM »
I've bought my pumice from Air Vol Block in San Luis Obispo, CA for a few years now.  It's inexpensive there and good size, however there's al ot of white dust on it which clogs drain holes so I usually wash it.  I use alot of it, both for collected trees and in my mix for Bonsai.

Generally I wash the soil on my slopped drive way out front.  The white water flows down my drive way and along side the curb past a few houses and then into a street drain.  Problem is this makes me a bad neighbor because the white chalky pumice powder is left along the curb when finished.  Any suggestions about how to not make such a big mess?  

The way I wash it is by putting a 5-6 scoops into my sifter and rinsing it until the water runs clean.  Any suggestions on a better way to do this?

Do you sift/grade it prior to washing?

The pumice I get only has minimal dust as it is washed prior to bagging, but I just sift the bag dust out prior to using it.

You could filter the wash water with a pillow case with a high thread count.  Drill several holes in the bottom of a 5 gal bucket, place the pillow case in the bucket and fold over the open edge of the  pillow case over the bucket's rim.  A bungee cord could be used to hold the pillow case in place as you wash your soil media to remove all fine particles.

I've rinsed the pumice I have and simply waiting for the area with the powder to dry up, and then sweep them up.  That'd be the thing I did if I was in your predicament.

Thanks All! The pumice I get must be pre-refined because it's the most dusty pumice i've seen before.  You can purchase it by the yard at Air Vol Block and it's not bagged.  I ended up just doing the washing over a large container and letting it settle for a while, before pouring the water on my lawn and dumping all the wet gunk in the trash.  Worked okay.  I like the pillow case idea, think i'll try that next.

can I ask how much they charge for the pumice?  There are no bulk suppliers in my immediate vicinity, and the commercially bagged stuff is too expensive.

I pay $18 per 25kg/bag in Australia, it'd be interesting to see what others pay?

Bob, I think the makers of dry stall are in Richmond Ca, not a too far of a cruise for you.

It's a good spot for pumice and lava(small cinders).  Super cheap.  I think 6 buckets is like $10 or so.  You could get a yard which would last you forever for like $60 or so. However, the pumice is super dusty, I've never seen any more dusty so you will have to wash it.
