Good point Frans I think Gertrude Stein said a Rose is a rose is a Rose and in chem class I have been known to say sodium chlo ide is sodium chloride   Grin

Dear,

    Coarse salt is more PURE ! Dissolves in 3 days as I use it   : 100g till 400 mL  / Use 2 times a day 10 mL over the steamed meals .=5g NaCl /day is an EXACT  MUST 

Fine is faster to use  But here spoiled with anticoagulant NaSCN ! FOR SPOILED PEOPLE .

Worth depends for WHOME ….!

For me coarce is worth most .       But Kg fine =Kg coarse .NaCl

 

Regards

F.

Understood. 

 

They purification process is done very well. There is a local preference for it but the market is not large. 

 

The big problem is Lombok is stripping trees from other islands, they need so much energy. I saw salt being made with wood, coconut husks, corn cobs and rice hull. 

 

Is fine salt worth more or less than coarse? Who thinks so?

 

Thanks

Crispin

Yes I see now, sea water is around 35 gram per litre and boiling water
saturates at over 400 grams but I couldn't see where the extra  salt
was coming from so assumed they were evaporating from sea water rather
than a more concentrated brine.

So if they were starting with a concentration of 20% salt then they
would only have to evaporate 320 litres of water instead of the 2000
litres I first worked out ( I also misread a decimal point one place
in the saturation point of brine).
