I am after some direction in regard to this unusual stone/rock I found and how to identify it (see the attached).
What I can tell you is that it is dark green in colour, I chipped a little off following instruction on a meteor website thinking it was from the great beyond but its brittle and the small piece that came off was like shattered green class through which you can see light. Its also smooth to touch.
This was on a public footpath near a farmers crop field just before entering a wooded area in the village of Old Walden.
It is about right in weight for the size, maybe its a resin?
Thank you for your time and thoughts in advance
In some ways it looks like a piece of modern glassy lava. But in your situation, I feel it is much more likely to be a piece of waste glass. That sort of material is sometimes used for making-up footpaths.
You could test for it being resin by its density: resin should be less than 2g/ml; glass more than 2g/ml. That should cover most of the range of chemistires of resins and glasses (that range makes using hardness less useful as a discriminator).
Thank you Mike for taking the time to reply - it is a piece of slag so I have added it to the rock pile around the water feature. Still its brought me to this website so it was worth the find.
It appears to me to be a piece of silica, Slag
Do you know of any old local industries, the test for resin is a red hot needle, ie does smell and melt at reatively low temperatures
Thank you Steve for taking the time to reply - its a piece of slag as you suggested so I have added it to the rock pile around the water feature with the other finds. Still its brought me to this website so it was worth the find.
I've found the same thing in the same place several times over the last few years, I'm pretty sure it is furnace slag as Steve Jeff says and that it was imported to make up the path. There is more in the old railway track bed not far away too.
Thank you for taking the time to reply and for the advice on the railway track, we are going to head out this weekend to check it out and explore the area a little more, the dragon fly's in particular up that neck of the woods are a sight to see not forgetting the giant hares. All the best.
