Well I was told that you can use brick in your tumbler. It's for catching any impurities and also to polish the rocks better it's even supposed to shorten the time needed for tumbling it(!) Anyone know if this is true?
PS. small pieces of brick it is.

I'm no expert yet, but it seems like a porous product like brick would actually cause problems by hanging onto grit and then releasing it when you least want it.

....which might be just the ticket in course cycles, I might have to give it a try.
I agree that it'd be of doubtful advantage in any of the medium to fine cycles though.

I am also on it, at this moment I've run my rocks 4 days on thursday I'll check them. I did check them on monday it seems well on rough. Not sure on the others. Regards, Eu |

Hmmm... If you used the brick like you would beads - separated by cycle - wouldn't it be similar to running ceramic media with imbedded grits? Would the brick last that long?

The brick does last about 3-5 days.( approx 3-4 cm pieces) I've never run ceramic media but the brick is not as hard as the ceramic media I think?? |

If you mean real bricks (not the "manufactured" stuff that I think are cement) I think it would be very soft. I use my non-abrasive ceramic media a lot and only see the points wear down. Doesn't seem to affect the rocks but may make a difference for metal burnishing. If you are using fake bricks you are doing about what the people that use pea gravel are doing (adding small sizes to speed up grit contact).

There's a million tumbling tips and old-school formulas out there. Not at all inclined to chuck a brick in my tumbler, I must admit. Sure you need small stuff in there to cushion and grind the concavities of the larger pieces, but I don't think brick would be much use; pea garnets or small agate chips do the job and come out with a lovely polish to boot. The idea of "catching impurities" is complete nonsense. MYTH BUSTED!  SirRoxalot |

I was using some really dense quartz material that is use for countertops. I crushed it up and used it instead of grit and it ground away the softer material on the T-eggs and shaped up the cores a bit. I think the brick may be adding something to the grinding action. There might be smaller pieces of quartz or other minerals mixed in the formula to make the brick. Hey if it is free and not to time consuming go for it.

Spirit Stone: It's good but only for the rough step and freshly crushed material.
(note I tested with crushed white quartz)
It's not free but it's darn cheap and easy to get your hands on.
It's mainly burnt clay...(not sure exactly what this clay does contain)
