Use made of to talk about the material of an object - wood, plastic, glass, crystal, etc. which has not gone through very much processing. You can still see the original material:
- This table is made of wood.
- The window is made of glass.
- This shirt is made of cotton.



Use made from to talk about one object that came from another, different object:
- This purse is made from recycled plastic bags.
- Cheese is made from milk.
- Wine is made from grapes.

In each of these cases, you can't see the original materials anymore (plastic bags, milk, or grapes); they have been transformed into something completely new.
