Oooooh this looks familiar, Shornemead Fort by any chance?

Funnily enough I know exactly where Local Hiker was Walking.
I will pass for a while,hopefully some one else from the 180  members will join in with a guess.

Hoo identifies the correct part of Kent, so is heading in the right direction.

Hoo?

[Local Hiker]

Thanks grandarog.


I went there a couple of years ago, the week after it shut for winter, and after heavy rain. There was no cafe, no toilets, lots of mud and mulched leaf litter, and flooding on the paths. It is definitely worth a visit, but I shall return one summer on a hot dry day!


Next GTP, an autumn walk back in 2016.

Fascinating stuff everyone.  Going to dig my chemistry set out

Yes, your mixture is basically correct: roughly 75% KNO₃ with the remainder charcoal and sulphur.  Charcoal was usually in excess but compositions vary.  Blasting powder for mining and quarrying has less nitrate.  Sodium nitrate can be used and is as powerful, but is hygroscopic and therefore deteriorates faster unless kept sealed.  However, du Pont  manufactured a low-sodium nitrate form where the grains were coated in charcoal yto keep them dry, this was only for quarrying.

Thanks MartinR. I didn't know what an "incorporating" mill was ,that,s why I asked.

Each millstone weighed approximately 3 tons and the ingredients of sulphur, charcoal and saltpetre were milled for up to 5 hours, in batches of 50 lbs. The incorporated mixture was known as millcake.

I think that sulphur ,charcoal and saltpeter equals basic Gunpowder.
Cast iron sounds a bit dodgy with Gunpowder involved.

[MartinR]

They are the bases of the incorporating mills according to the link that Local Hiker gave.  This is mill at the Hagley gunpowder mill.  I believe that British practice was to use stone runners, not cast iron, but it gives the general view.

[grandarog]

You have it Local Hiker,over to you. 


Does anyone know exactly what the bases were for?

I delayed calling it until I sorted something out to carry the game on. I am getting short of GTP material.

[MartinR]

Part of a gunpowder works?

[Local Hiker]

This one should go with a bang...

[grandarog]

No .
1st Clue ............ Industrial.

Stand for taking a salute?
