Salty

I’m so near the end of my next Thomas Radwinter book… gosh it has taken a long time, it has been a real fight! partly because my life outside writing is very hectic, but also I think I put an unrealistic time scheme to it, thinking I would get the first draft completed much sooner. As usual I’ve had to do some research for various narrative lines – quite light research compared to what other writers do, but the things I ma researching are just background to the main story – so zeppelins and salt seem to be the two threads with this story!

Here is something I wrote about salt last year:

Salt, or sodium chloride is a mineral which we need to survive, and for most people in the modern western world our diet has more than enough – in fact sometimes too much salt! It’s not just that we add it to food we cook and food we eat, it is present in a lot of food which we buy, sometimes in surprising amounts in surprising food. We might expect it in savoury foods, but it’s also in a lot of sweet foods, and also in products we might not consider as food – toothpaste, medicines and pain killers.
But where does salt come from? Salt mines and the sea… I have been researching salt production from sea water because it features in my next novel, possibly called ‘Saltpans’ – which gives a big idea! From Roman times, if not even earlier, people obtained salt from the sea; in hot countries sea water was held in vast shallow lagoons which would evaporate leaving crystals of salt – it has been done for millennia and it is still done today. However, in our cooler climes, it was necessary to evaporate the water from the sea with human intervention. Sea water was contained in bucket pots, and some evaporation would occur, but then the salty liquid was pumped – sometimes using windmills, into salt pans, vast five meter square iron containers, the saltpans, which were heated, sometimes by coal, sometimes by wood, sometimes by charcoal to evaporate the remaining liquid. This as you can imagine put the pans under some stress as the salt was corrosive.
So salt is used in and on food, as a flavouring and as a preservative, but it has many other uses:

  • tanning
  • medicine
  • chemical production
  • the chlor-alkali industry
  • the soda industry
  • gas and oil exploration and drilling
  • textiles and dying
  • processing metals
  • paper manufacture
  • white rubber manufacture
  • soil additive
  • de-icer for roads
  • salting food
  • in the food industry in many, many ways
  • fire fighting
  • household cleaner
  • windows and prisms
  • … and no doubt much, much more!

It is an amazing product, and it’s no wonder the Romans used it in part payment of their soldiers!
