I would like to add:

I'm old enough to have seen all those doorstep milkbottles with caps
standing an inch or more above the bottle rims in 1962/3 winter

At what temp would this occur?

I forgot to bring the milk in on Wednesday until late afternoon and,
because we are 600ft asl on a NW slope there'd been no sun and well
below freezing temps all day - I expected the lid to be pushed up but
it wasn't.


Whatever the coldest overnight temperatures were over the early 1960s, I
don't have the data. Cold enough for sea-water to freeze at Weymouth,
Broadstairs etc

I can remember a couple of mornings when I was at junior school when the
school milk had ice on top. That was probably in February, 1956.

It would have been full-cream milk only in those days which may be relevant.

Yes, presumably the creaminess of the milk would affect the freezing
point.
