Cloudy Clear Stones Identity?

Just post your photo's to any Internet Photo Sharing site and then put a link to them here. Then we can see them. Thanks.

Agate jumps into my head

There is a way to place a photo in a posting but it's so complex that after 17 years trying I finally gave up

My very intelligent and otherwise helpful No. 2 Son just concluded a visit during which he attempted to show me and following his instructions in fact I was apparently successful; but I don't remember how I did it

And Rod our session had lasted some two hours, and yes I took notes. There were about 16 steps I intend to try some day

Stones may be gypsum.I also have an unidentified petrified?

Bob I'd guess calcite, but lotsa rocks look like that

theyre hard to tell. Cold be anything from alabaster, selenite to calcite or cryolite. Fossils can occur in gypsum or calcite. How bout hqrdness, whaat is it? >2 on Moe's scale.

Does it fizz if you drop it in a glass of vinegar. Does it dissolve slowly in hot water?

it should be easy to tell, but I dont think the pictures are good enough tom tell accurately.

The fossil seems to be either a belemnite or a crinoid.

Lord God Man, wish I remembered all that stuff. But I don't think all those calcium minerals fizz in vinegar so you might comment


See above reaction

it isnt the calcium but the carbonate. Limestone and calcite fizzes in vinegar (or HCl) dolomite only fizzes when its in a crushed form. Both are carbonates.
siderite fizzes only in HCL nd quartz fizzes in Hydroflouric acid(which I dont rev=ccomend anyone carrying in a field pack)

Hrdness , gravity, streak etc are still valid tests for the simpler ones. We dont need n Xray or some more complex gizmos.

Several minerals slowly dissolve in hot water and you can add test solutions to draw a color corresponding to the major metal ion that is the base of the mineral

f@#king geologists !

There's one under every rock.

Yea, but I love farmerman's knowledge in this field.

Me too Cis, really impressed with it

I was avid rockhound but now old and retired I often have to ask my BH for the name of a common rock

submarines and targets.

hes got 2 other thrads and wweve told him what hes got. Hes just looking for more attention.
