The threshold seems to be around 120 deg F.
Pre heating the water to 'luke hot'?.. around 90 to 110 deg F and letting it cool while making CS induces a thermal stir effect that does well on small batches.
On larger batches, the stir effect slows down when it's needed the most.
Preheating also increases intial water conductivity to speed things up when it does the least harm, that is, when there are very few particles to collide.
A pale yellow CS is not "bad".. it could be better, that's all.

Hello everybody,<<<<
I understand from a previous question, about heating CS, that this is not advisable.
As I am making my own CS since last week, I am still in the middle of experimenting. For instance someone advised me to use 500 ml cold, and 500 ml heated (not boil) water, so that the total of 1 litre would be around 60 degrees Celcius. This warm temperature would make a better CS I was told.
Uptil now I got a cristal clear, colourless quality of CS by using sterilised - only cold - water from the chemist. But when I warmed half a litre and poured it with the cold half a litre, the endresult of the CS was light yellow, not cristal clear colourless.
Is it right to conclude that heating part of the water is no good idea, perhaps because of mineral parts from the kettle?
Another question: what sort of quality is CS with a light yellow colour? Is it only good enough to water the plants for instance, but not good enough to ingest?
Thanks, and looking forward to your reply!
