Today I started dissolving samples of Rochester Fm (Silurian) from upstate NY, Jacksonburg Limestone (Ordovician) from a quarry near Bethlehem, PA and finally the Whitewater Limestone (Ordovician) from Indiana.

My plan was to allow the limestone to dissolve in the vinegar solution for a couple of days in order to create the buffer solution. Well other things came up (i.e. work) and I didn't look at the solution for a couple of weeks! :o
When I tested the solution, the pH and density indicated that it wasn't diluted to 7%. Something...

Before dissolving the limestone slab, a buffer solution needs to be made. The buffer solution moderates the dissolution and keeps the solution pH from starting too low which can damage the microfossils from the slab.
After mixing a 7% solution, I added a spare piece of limestone start making the buffer solution. The pH started at 2.5 and had...

Last year at a club auction I bought a slab of Ordovician limestone from the Whitewater Formation in Indiana. It is covered in bryzoans and brachiopods.
It seems a shame to dissolve it but I've read that the Whitewater contains many species of scolecodonts and the only way to recover them is to dissolve the...
