Detailed Solution

The above statement is true.
The steel spoon and glass bowl shine due to their lustrous properties.
Lustrous means shiny. It is the property of metal whereas non-lustrous is the property of non-metals which means not shiny. Or we can say that lustrous materials are those which are shiny. Examples of lustrous materials are gold, silver, copper etc.  Examples of non-lustrous materials are wood, paper etc.
