Metal crockery gets expensive coating (6,5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
silver plate
'expensive coating' is the definition.
'silver plate' can be an answer for 'coating' (silver plate is a kind of coating). I'm not certain of the 'expensive' bit.
'metal crockery' is the wordplay.
'metal' becomes 'silver' (silver is a metallic element).
'crockery' becomes 'plate' (plate is a kind of crockery).
'silver'+'plate'='SILVER-PLATE'
'gets' is the link.
Can you help me to learn more?
(Another definition for silver plate that I've seen is " Valuable metallic ware".)
