Slag glass in tank?

[sweetcarolinex3]

I found the mother load of the coolest slag glass! A lot of it has been warn down but others are still sharp enough to cut you finger... Is it too risky for my tank?

Yes very risky. I would run it through a rock tumbler to dull the edges or sand paper all sharp edges

I've never heard of a rock tumbler. What is it?

Somewhat self explanatory but confusing at the same time. Pretty cool item. Here's a link. http://geology.com/rock-tumbler/
