made of/from

[irinaofr]

The shoes are made of leather
The shirt is made of cotton
The cheese is made from milk
The vine is made from grapes

Why?

Why...?

If the material is clear with the product- a wooden chair looks like wood, then we say 'of'. When the process changes the material, then we say 'from'. If you hadn't been told, would you associate wine with grapes?

Hi,
I wonder if the following formula fits all the cases:
made of - for countable nouns
made from - for uncountable ones

That sounds attractive. (Another one that I'm going to have to go away and think about. )

I don't think it does:

It's made of plastic.
Cider is made from apples.

I meant the resulting thing, Tdol. Here, cider.

My teacher told me that the material at the 2 side of 'of' are obviously the same, while that at the 2 side of 'from' change their form greatly.

I hope someone give a definite answer.
