Delft blue - Delft, The Netherlands
Picturesque city - on Delft the phrase can be used literally. We spend hours walking through the paved streets and little bridges, sitting in a cafe, watching the passers-by, and, of course, taking photographs. I do not think that photographs reproduce our feelings completely, but if it succeeded at least in part, it is a good thing.
Channels are covered with green ooze (sometimes with water lily), as if with a carpet. And, almost as on the old mats on the wall, this carpet has swans as well.
Online you often encounter phrases like "surprisingly looks like Gzhel" or "I will call delft - Gzhel". In fact, "Gzhel", as we know it now, appeared in the 19th century, when the skilled workmen from the small town Gzhel by Moscow created a combination of faience with cobalt blue.
I do not know whether the method was borrowed or created independently. There is, however, no doubt that "Gzhel" was made under the influence of "Delft Blue", produced since the 17th century. "Delft Blue", in turn, was not born out of nothing, but was a response to wide distributed Italian majolica.
