, but yes - the decorative effect is similar to his later 'cloisonne' pieces where a variety of his shapes/colours show this crazed/crizzled appearance, and would agree with you about the 'speckled' translation. Can't see this one looks like marbling though, which is more correctly described as a soft liquid flowing of swirled lines.
Gary is probably laughing at my dipping toes into an area about which I know s-- all, and my comments are taken only from pix I can see in the stunning Parkington collection of Scottish Monart glass that appeared in the sale catalogues (2) back in 1997 and 1998.

Forgive my ignorance, but are you trying to make the case for some potential connection between the Mataro Glassworks and Salvador Y, or is it just that this piece looks like Salvador's later work. Maybe crackled/cloisonne surface decoration was big everywhere just prior to WW I - am I wrong, or do I recall this colour/effect occurring in WMF glass also.
