Hello, I just bought 33 un-opened mazon creek fossil nodules, and the seller said its best to use the "freeze and thaw" method. What is the "freeze and thaw method? how does it work?Thanks

Put your nodules in shallow tubs of water....put in your freezer until frozen....thaw....repeat. The water will soak into the weakest part of the nodule - the fossil - and expand when frozen. The nodule will neatly split at the fossil. Be patient. It takes many times.

or for the impatient try a microwave (if you have a spare one)! Oh and be careful lol!

I'd never heard of that method either but it makes sense... really cool! (no pun intended)

put them in the freezer until the water freezes solid....will depend on how deep the water is. Thaw until completely melted - again, will be determined by the depth of the water. A shallow tray will allow more freeze/thaw cycles per day. I don't recommend running under hot water to thaw them - you can crack them in places where the fossil isn't. The freezing opens the nodule, not the thawing.

OK, no problem ;)

BTW, how long does it usually take for them to "pop" open?

"A watched nodule never cracks"; just keep doing it until they do :)

but if there is no fossil inside, ther will be no airpocket for the water to get into, resulting in a nodule that wont crack. right??

At some point, there was an organic mass. That's what the nodule formed around. There are "empty" nodules where the organic material did not preserve. It will however make a weak point in the nodule, and that's where it will split. You may have to freeze/thaw 50+ times for a stubborn one.

If you heat them first before putting in water. as they cool in the water the air inside will condense and draw in more water speedin g up the whole process.

Don't speed the thawing!!! (Think throwing hot water on a piece of glass....) CRACK (and not where you want it)

Hi, does the water needs to be changed after every freeze and thaw cycle?

Great!!!

How many freeze/thaw cycles did they take?
