As you know glass is a transparent (or translucent) substance, however can opaque glass make sense? I don't use a metaphor but I want to talk about a literal sense.enter image description here

For another example, can the orange in the picture above be called 'blue orange' even though 'orange' means orange color fruit?

  • @TypelA I know but I mean 'golden apple' means 'golden green or red apple' because 'apple' means 'red thing'?

  • Sorry, I don't understand. Apples come in different colors, including red, green and yellow. You seem to know this. Gold is a yellowish color. Something that is gold-colored is golden. Hence, golden apple. "Apple" does not mean "red thing," it means the fruit of a Malus domestica tree.

  • @TypelA so I defined apple as the round fruit of a tree of the rose family, which has thin green or red skin and crisp flesh

  • I guess we're talking about different fruits. Like this? I have to admit I'm not familiar with this fruit, and it's not what most English speakers think of when you say "apple" by itself. Is this really a horticulture question? Are you asking if this particular fruit has a yellow variety?

  • @TypelA I give you another example, if 'sky' means 'blue sky,' is 'yellow sky' a contradiction?

Does opaque glass make sense?

Absolutely! There doesn't need to be anything symbolic or metaphoric about it.

There exists a manufacturing process where they mix some additional material into the glass that makes it "hazy" (usually white in color) to the point that it's barely transparent any more.

I recall seeing various kitchen equipment of this sort, like bowls, plates, cups, and in particular, heat-resistant baking utensils.

Their appearance can often be characterized with a "milky" impression, and they get decorated with moderate amounts of colorful (hand-) painted ornaments.

  • Though the dictionary defines glass is translucent or transparent (not opaque), it doesn't matter?

    The dictionary was narrow-sighted in this case. Or perhaps, they had a limited space for the word definitions, and they could not afford to go into details about something that applies only to 3% of all glass products. Though I still think they should have been able to squeeze in the modifier "most often transparent" into a definition describing glass.

  • Some alcoholic beverages are distributed in bottles made of entirely opaque glass. My after-shave sits in an opaque glass flask. You will likely find numerous further examples to products packaged in opaque glass in a drogerie's body-care product-lineup.
