'If'!

Oh, I misunderstood what was in the image as meaning it was going to be in Germany. sorry

Slippy in wet and icy conditions although, yes tough enough for the ages otherwise.

Oh, believe me, there are sinkholes and water main leaks washing away substrates absolutely everywhere.

And the joints/seems with the next surface along. When the Construction Historian is the democratically-elected president of the world, all road works, cable-laying etc will be required to relay the whole width of any road/footway they dig up....

Freeze-thaw cycles are the key destroyers of many surfaces. I was just commenting to MOH that our local road is looking set to be potholed come winter, due to the many cracks all over it.

And, right there, you have the explanation for the problem. This is commonplace in cities that used to have cobblestone roads (Sets in Scotland), especially if they are granite. Tarmac doesnt stick to the granite, so any damage by frost or heat, quickly pulls tarmac off. Oil drips soften tar too.

Is it known what they might have been trading in then?

The Construction Historian loves Prestongrange - a great museum. Lucky you with the weather - it has been a tad wetter over in the West.

There is a lighthouse exhib at NRS. Must get there.

Haha! thanks

It's easy to assume that everyone will share your enthusiasm It is no secret that the Construction Historian likes a nice brick but the attitude to saving large collections at the national level seems to bring out wholly different opinions.

Much in the same way that scanned archive documents often blur/obscure/miss out vital information at the edges, middles etc.

Because?

Thanks. The variations on the frog markings can indicate date, type or which worker made which bricks. No company catalogue will tell you that.

Thanks. I am pulling all the comments together (anonymised of course) for someone who is hoping to find a home for a very substantial collection.

#3. That such lists exist. Actually in many cases these lists are not complete by any means and this has been an area where amateurs have been more thorough than the professionals, who tend to give up at the 'good enough' stage.

3. I cannot think of an instance when one would want to consult a brick collection. The storage costs are huge. Lists of makers marks are useful but these are already published. 3/3

2. Enormous number of these brick collections have come up over the years & they have always struggled to find a home. These discussion have been had countless times. Bricks take up a huge quantity of space & they really are never accessed. Who would use them and what for? 2/3

🧵Some negative opinions: 1. No shortage of bricks in buildings & as 19thC bricks were made literally in millions a month it is extremely unlikely that any brick manufacturers bricks aren’t still in hundreds of buildings. What purpose would a brick serve, abstracted from its source? 1/3
