Yes. I know that there are some in Santiago, so there must be more artisans doing that type of work on the island. You want to look for someone that does "vitriales", which is what they are called in Spanish.
Here are some panels from my house done by a local artisan shop in Santiago.
Excellent! Thanks for the photos and the translation. I am a leaded glass artist, and I'm excited to see glass work done by local craftspeople when I visit.
