Type 4: Special Noun + Noun STRESS ON SECOND WORD
4a: The First Word is a Material of which the Second Word is Made
The 4a. examples are sorted into the following groups: Clothing Materials; Metals and Construction Materials; Jewellery and Precious Materials; Food Materials; Other Materials; Energy and Fuel Materials; and, Chemical Materials + A Process or Activity.
Note that many (or most) of the audio recordings available on the internet are recordings of expressions or 'set phrases' that can be found in the dictionary. These expressions are often not literally true. For example, "an ivory tower" is not really made of ivory and "a glass ceiling" can either be a true ceiling made of glass or it can have a figurative meaning.
But, whether the word combination is an expression or a true description such as, "a glass table top", the way you say it (i.e., the stress pattern) is the same.
