Santa Clara Del Cobre - Casa Zarco Vase

I picked this beauty up at a local estate sale this morning. 13" tall, 10" wide and weighing in at 7 lbs. It's marked at the bottom: Casa Zarco / Sta. Clara Del Cobre / Mich.

Would love to learn more about it. A few questions below but if any other facts or comments I'd really appreciate it.

Anyone know anything about Casa Zarco, or how their work is considered among the other workshops in town?
Can the design or mark help anyone guess which decade this might have been made?
Does anyone know how or why it appears white/silver below the scratches and carvings?

 

Wow! 250 workshops in Santa Clara del Cobre according to wikipedia.org. I can only find a mention of Casa Zarco in a 1989 issue of a publication entitled La jornada semanal.

Oh! Oh! Here's better luck. A couple of videos and a press account. Zarco is a common (and apparently prominant) name in Santa Clara though. There's both a Zarco street and a Zarco family. Not sure these are about the same taller (workshop.) Can't find anything more about a "Casa Zarco."
