It's interesting how a chance remark can lead you to an adventure, @slowwalker.

You enjoyed a sunny beachside walk to visit a marine museum and discovered there innumerable porcelain treasures.

My favourite was the greenware vase you featured toward the end of your photo stream - the glaze was magnificent.

It's one of the curiosities of history that such shipwrecks endure and manage to offer up such priceless artifacts.

I recall reading about a Roman wreck being found with intact amphora of wine almost two thousand years old!

I would certainly not sample that but it is remarkable it endured so long.

As for your lovely vase, as Keats said, a thing of beauty is a joy forever.

Have a good day, my friend.
