For a presentation, I am trying to say "These works of art are no longer made." I'm having trouble figuring out what verb tense I should use, though. So far I have:

"Estas obras ya no..." but I don't know how to finish the sentence. Son hecho? Fueron hecho? Han hecho? I can't figure it out. I know this might be easier if I phrased the sentence in the active, rather than passive, voice, but I'd prefer to write it this way, in light of the rest of the paragraph.

Thank you for using the Jiskha Homework Help Forum. This is a good spot for the passive: Ya no se hacen estas obras.
