Hey all, so my wife surprised me by ordering both a large and medium box geodes from the gem shop. The last time the collective weight was 5pound and had some agate geodes. This one is 7 pounds. Generally the gem shop boxes tend to be nice in terms of geode cavities. While it might mean most of the geodes are filled, is there a senario where a heavy weight is in a geodes favor?

I have no answers but your wife is a star Yup, she is. I want to buy a thin 7 inch tike saw blade. Continuous. The segmented ones carry risk that I don't think my wife would bear.

I would say yes. Although it would depend on where the geodes originated from, and thus there mineral make up. Geodes from Indiana and some I got from Kentucky for example seem to be a lot less silcated, and often solid. They seem softer like maybe more calcium based. If the geodes are from an area known for agate or quartz crystals inside, the silicates would give the geode a higher density.
What would be interesting to experiment with is tapping the geodes with a metal object like a rod and learning the sound differences as a hollow geode would transmit sound differently than a solid geode.

A 7 inch blade will not give ou much of a depth of cut as generally the blade only goes about 1/2 inch above the table.. I recommend getting a 10 inch tile saw. Continuous rim blades are easy to find for these, and they will give ou a much deeper cut, around 4 inches.

wargrafix if you want to open a geode and your saw is not big enough, and you do not need to have a sawed face then go to Home Depot and rent a soil pipe cutter and use it to crack the geode. It will make a nice "as smooth as you can get without a saw" fracture of the geode.

I have spoken to ppl in the oil industry and they looked at me with confusion on what a soil pipe cutter was.
The pull technique of the saw...do you all roll the rock away from the blade, or into the spin?

Check with plumbing people. a "soil pipe" cutter is for cutting cast iron sewer pipe. so it is soil pipe as in "night soil" ... people excrement used for fertilizer.

Chain pipe cutter would do the trick too, we used them in the oilfields in Montana and North Dakota...
