More Rabbit-Trailing, or: White Cliffs and China Clay

I’m still rabbit-trailing, uh, sorry, researching. And for some reason, I always seem to arrive in the early 19th century again – the time of the Regency, Jane Austen, the Brothers Grimm. What’s with that?

This is how the rabbit trail ran today: I was looking at the creation of porcelain or china (because that’s important for Septimus book #3, Checkmate, which I’m editing at the moment). Unlike regular clay, which you can just dig out of the ground and use more-or-less straight up, the clay body that makes up porcelain is a mixture – the recipe varies depending on what kind of china it is. Bone china, the fine English stuff invented by Josiah Spode in the late 18th century, contains a sizable proportion of actual bone (cow, for the most part, apparently), which is burned and ground up before it gets mixed with the other ingredients. Recipes for china clay were a closely guarded trade secret; in fact, when in 1712 a French Jesuit missionary transmitted the secret of how to make porcelain from China, where he was working, to Europe, it was considered one of the first instances of industrial espionage (however, some German scientists had already figured it out for themselves a couple of years earlier, establishing the porcelain manufacture in Meissen. Science beats spy work – so there!).

Now, that key “other ingredient” in porcelain is kaolin, also called, for obvious reasons, china clay. Kaolin, one of my sources informs me, is really white, and is primarily found in Malaysia and in Cornwall, England. And here’s where today’s rabbit trail comes in: my mind goes, “White deposits of mineral? In Southern England? Wait – the White Cliffs of Dover?” Back to Google I go, to find out what you probably already knew and I remembered just before Google brought it up, namely that the White Cliffs of Dover are made of chalk, not kaolin clay.

So, of course, I had to look that up, and remembered and found the famous work by Romantic painter Caspar David Friedrich, “Chalk Cliffs on Rügen”, from 1818.

And there you have it: the research rabbit trail arrived in the second decade of the 19th century. Just look at that dress, and the hairstyle of the lady! In 1818, Persuasion was published – can we picture Anne Elliot in that outfit? If it wasn’t for the two gentleman in the picture obviously being civilians, it might well be showing Captain and Mrs Wentworth on their honeymoon (they took a friend along on the hike to the cliffs, okay? There’s nothing wrong with spending time with friends, even if it is your honeymoon). Or it might be Jacob and Wilhelm Grimm, on holiday with their sister Lotte. And when they get back to their Pension (bed-and-breakfast, or inn), they’ll have a lovely Kaffee und Kuchen (afternoon coffee & cake) off a set of Meissen porcelain.

Life, the Universe, and Rabbit Trails from China to Jane Austen. The pleasures of a writer’s life.
