Accidently posted this in rock carving first, and then kind of tried to delete and, Im a disaster. Sorry.
I recently saw a quick mention about tumbling pudding stones (conglomerates) and I was wondering if anyone has any experiencing with this? I dont have any pudding stone rough right now, but it would be fairly easy for me to collect it. I am always looking to learn about tumbling new types of stones, because right now, I dont buy rough and only tumble rocks I have found (btw, I am very new at tumbling, and quite frankly terrible). Anyway, if this stuff is good for tumbling that would be great for me. Thanks.

thats ok. I'll move reply here too ..... I put pudding stones in just about every batch I run so that means I get some done every week. All of my pudding stone is self collected so that's why I use so much of it. It can be a good looking rock when done but it will never be a nice smooth tumble like jaspers and agates are. Because it is a conglomerate each rock thats cemented together gets eaten away differently by the grit so you always have a somewhat bumpy finish and they are also prone to pits and fracture lines where the rocks are joined together too. here's a small example of my last mixed batch that had some in it. forum.rocktumblinghobby.com/index.cgi?board=trtphoto&action=display&thread=59469Chuck

As for process I treat these like any other rocks and even though I have run full batches with nothing but pudding stone I dont see any difference in the ones that go in my mixed load batches.
4-6 weeks (or as long as needed to remove flaws) in 60/90 checking each week and setting aside any that are ready to move on to the next stage.
1 week in 120/220 rotary (or 2 days vibe tumbler)
1 week in 500 or 600 with ceramic pellets added for cushion in a rotary tumbler (or 2 days vibe tumbler also with added ceramics)
1 week in 1000 a/o pre-polish with ceramic pellets added for cushion in a rotary tumbler (or 2 days vibe tumbler also with added ceramics)
1 week in a/o polish with ceramic pellets added for cushion in a rotary tumbler (or 2 days vibe tumbler also with added ceramics)
12-24 hours burnish with borax and ceramic pellets added for cushion in a rotary tumbler (or 4-6 hours vibe tumbler also with added ceramics)

Thanks for the info. I will try throwing some in when I start my next batch. Your pudding stones look great, what state are they from? I live in nj.

Chuck's stones are from Michigan. I don't think the pudding stones from New Jersey are the same kind of stones.

We have found all of our pudding stones on the shores of Drummond Island, Michigan. It's a very popular stone there and the Islands website even has a webpage about it. www.drummondislandchamber.com/index.php?page=PuddingstoneThe local bakery evens sells pudding stone fudge that looks just like slices of the rock when you cut it up.
