Largest stone sundial?
Hello, Does anybody know what the largest one-piece stone sundial in the world is? Thanks, -- Dan-George Uza --- https://lists.uni-koeln.de/mailman/listinfo/sundial
Re: STONE SUNDIAL
Many thanks for everyone who responded to my request below. The best option turned out to be the British Geological Survey who can do a full petrographic analysis of the stone, then identify, provenance and stone-match it, for a charge of £400 plus VAT. However this is quite expensive, but if you give them your budget, they will say what they can do for that.

Many readers will find this a little puzzling given that Dennis lives but a stone's throw from The Cockburn Geological Museum at the University of Edinburgh whereas Cambridge is over 300 miles further away. The clue lies in the sign-off... Kevoin The superfluous "o" indicates that he was using a stereographic projection and, by assumption, Edinburgh was the pole of the projection.

RE: STONE SUNDIAL
Hi, This is not quite as simple a task as it may appear. A lot depends upon the nature of the rock and the sample available. If the rock is very distinctive, a visual examination may be all that is required, but I rather doubt that will be the case. If it is a piece of limestone or sandstone (as I would guess) then it may well require a thin section to be made (this is a small piece glued to a glass microscope slide and then ground down to 30 microns thickness, for examination under a microscope). Making the slide and getting it to the correct thickness, is a skilled business. Even then it may not be possible to say exactly what rock type it is; saying it is limestone or sandstone (for instance) is easy, saying which one is much more difficult as rocks can be quite varied and the sample size is bound to be small, so any error may be large. A lot may depend on knowing where the dial is situated and whether it has always been there, as it is unlikely that a piece of rock would be transpor ted large distances just to make a sundial. I think it is unlikely you will be able to tie it down with any real certainty. There are no absolute determinative tests to determine what exactly rock type it is; it is all a question of mineral content and amount, but as I said that can be very varied over the length of a stratum of rock, even though it is the same rock and even the same bed! If it is a limestone and contains any kind of determinative fossil (but it will probably be in fragments, so not easy to look at) it may be possible to say roughly what age it is and thus to determine where deposits of that age are found. But the chances of this being the case are highly remote as most limestone simply contains crushed fragments of typical fossils of the period. The obvious place to ask is the Natural History Museum in London which nominally runs a public ID service. I know because this is just the sort of public enquiry I used to deal with as a geologist there. However, I doubt now that they will want to do it as there are no benefits from doing so and there is a lot of work involved. Also there are not the staff there now to deal with these types of enquiry. If they do, there will be a charge for making a section (if it is needed) and for the identification (if it is possible), and it won't be quick. You are welcome to give it a try, but don't say I suggested it!
