Went for a drive tonight to see if the big DIY garden/buidling supplier here had thrown any goodies out. Found a 15kg bag of scoria sitting next to the dumpster with a cut along the side of the bag. Looks like I wont be needing to buy some any time soon. I will have to go through it and break it up a bit though, looks to be as round as a 20c piece.

Nice find. It might be worth asking permission, if you haven't already. Even though it is next to / in the bin it is still not legal to take it. just be careful either way.

you will definately have to crush it up if you could get it to about 5mm would be a perfect size for a potting medium additive

I use scoria in the bottom of all my Growing pots / boxes when I repot to stop the medium falling out. I do not uase it a spart of the medium
I like the 10mm size If i can find it

Ok ok, you caught me out with a little white lie. It wasn't next to the dumpster, it was in it with a heap of plastic, cardboard and a heap of broken tiles. I just said it was next to the dumpster because I didn't want people thinking I was a scab.

What is the best way to break up the scoria? Do I just put some in another bag and attack it with a hammer until I get the size I want?

Bretts is the expert at scoria breaking as I have had no success
Hit the odd lump with a hammer is too hard for me
