Hi Listees!

I have a Lortone Rock Tumbler (QT66 with two 6-lb barrels) and I
decided to put some very ugly and extremely-weathered up UNWA stones
into it - just to see what the result is. They have been tumbling in
coarse grit for 6 days now - tomorrow night I will open the barrel,
check them, and decide if they will need another coarse grit stage
before moving on.

Has anyone on the list ever tumbled meteorites? And what result did
you get? I am worried about water intrusion deep down into the
specimens, so I assume a good baking in the oven will be called for
when the tumbling is done?......or would something like silica gel be
better?

Best regards,

MikeG
