"made from" and "made of" - are they different

[lingua]

Hello teachers,

I am very glad to have found this site!! :)

I was wondering if there is a difference between "made of" and "made from"
or can they be used interchangeably?

Thank you

They can be used interchangeably, yes, but they are different. That difference is subtle:

This box is made of wood. <I carved it out of a wood block>
This box is made from wood. <I built it using wood>

This cone is made from honey. <Some honey was used>
This cone is made of honey. <It's all or almost all honey>

All the best.
