1. Something is made of something.
2. Something is made from something.

I want to know when to use "made from" and when to use "made of".

Please help me with a few examples.


If something keeps its form, we use 'made of''
But if the form is changed during the process of making, then we use 'made from'.

"The shirt is made of cotton."
"The house is made of bricks."
"The keyboard is made of plastic."

"Paper is made from trees."
"Wine is made from grapes."
"This cake is made from all natural ingredients."

We use the expression be made from when we can no longer identiy the material that was used just by looking at the object.
e.g. Almost all paper is made from wood pulp.
When you look at a piece of paper, there is no way to tell that it started out as wood pulp.

We use the expression be made out of when we can identify the material that was used just by looking at the object.
e.g. That old dresser is made out of knotty pine.
When you look at that dresser, you can tell immediately (by the look, grain and color) what kind of wood was used - if you are familiar with different kinds of wood, of course. [made of is an alternate form].

We use the expression made with when we mention onoe or more ingredients.
e.g. This paint is made with latex.

When I see this question, I find that I am able to answer it.
However, I don't know whether it's right or wrong to do so.
Because my grammar is poor too.
Could anybody give me some suggestions on it?
Because I don't know whether I should do the same thing when the same thing happens.

Many thanks in advance.
