You are right Emmi, :thup: Murano should be reserved for Murano glass only.
Mind you, that said, eBay don't help as their category listing for Murano Glass, automatically selects Sommerso as well, and most Murano Glass is not Sommerso.
Because of this, many listers, some of whom I feel should know better, list their lamp work glass as Murano Sommerso, and when corrected get quite shirty!!
It also sends out the wrong message that all Murano Glass is Sommerso and so novice glass collectors buy a piece described as Sommerso and genuinely believe it is.
So back to my last reply....this is where eBay could have a list of questons before posting to alert the seller....and show examples to help them.
Does anybody else agree with this??
