Glass blowing workshop tour in murano

I have no experience blowing glass but recall seeing at least one "experience" listed on Airbnb that included some handling of glass. I don't recall whether it promised actual glassblowing. Glassblowing is not something one picks up in an hour or two, so I assume you're looking for a workshop of significant length. Lampwork (for making beads and other small objects) would be somewhat easier to pick up during a short workshop, I assume.
