Made from atau Made of ?

Klo mau mengatakan "terbuat dari" itu pakai "made from" atau "made of"? Simak penjelasan berikut:

"Made from" digunakan apabila bahan dasar utk membuat berubah atau tidak kelihatan lagi bentuk bahan dasarnya. Contoh:
- Wine is made from grapes.
(sudah tidak wujud "grape", tp berubah jadi "wine")
- Paper is made from wood.
(sudah tidak wujud "wood" lagi, tp berubah jadi "paper")

"Made of" kebalikannya, bahan dasar yg digunakannya masih berujud atau masih tampak. Contoh:
- The chairs are made of wood.
(masih tampak bahan dasar "wood")
- The house is made of bricks.
(bahan "brick" masih tetap utuh meski sudah dilapisi semen)

Contoh lain:
1. This shirt is made of cotton.
2. The chair is made of leather.
3. The vodka is made from potatoes.
4. The tea is made from barley.
5. The watch is made of gold.
