made of? made from?

I was cleaning the house earlier. While cleaning the kitchen cabinet, I actually found several interesting things.

last raya's cookies and some packed dates

no, I did not found my cat in there, but i did found a pack of asam keping and a box of SINGA tea (the best!)

a pack of unopened goji berries @ wolfberries

and lastly, a pack of candies, made of yak meat.

yes, YAK.

The last two items were presents from a friend from Xinjiang, China. Some of you may find the yak candy a bit  out of the ordinary, but actually it tastes quite nice. (I tried one and never touch them again^^). On the packaging, it says "This product is made of the meat of the yak, a unique treasure of the snow mountain and grassland of the Qinghai-Tibetan Highlands.

Eating a candy made of yak meat may be a challenge for some, but deciding whether to use 'made of' or 'made from' is far more challenging for some people. So how do you decide on which to use? Is any of them grammatically wrong?

Actually both are grammatically correct, but it is used in different context. The natural characteristics of the given object would help to determine on whether to use 'of' or 'from'.

Take a look at these examples:-

Plastics are made from oil.

These boxes were made from recycled plastic materials.

That chair is made of wood.

Wardina's hat is made of raccoon's fur.

If you noticed, 'made of' is used when we can still see the actual materials in the end product. If we take a look at a chair, we can still see the wood. But when we look at a plastic bottle, we cannot really see the oil, so the phrase 'made from' is used.

So, for the yak candy, it is made of yak meat, as you can still see, and even taste the texture of the meat.

what about these examples?

The slipper is made of / from a tire.

These customs are made of / from animal skins.

This special dress is made of / from silk.

The beads were made of / from hardened yellow pine sap.

The box is made of / from gold.

Post your answers in the comments, then we can discuss them together!

In the meantime, if any of you are visiting western China, you can bring back anything for me, other than the yak candies ^^
