Well first of all it was a gut feeling,i have been collecting all types of glass for about thirty years in this time i have seen many signatures on Gordiola glass another signature is cuneo and one has souvenir Ibiza on it, the shapes and the enameling are copies or Spanish glass from a couple of centuries earlier ie canine and flora-fauna and flora,in Mallorca i had a chance to buy a book on Spanish glass but didnt have enough pesetas with me and many of the shapes and enameling were in it as typical Spanish,the Gordiola book mentions their new enamaling shop next to the furnaces,c1930,my final proof arrived a few minutes ago signed Gordiola Mallorca it was sold to me as Italian. also i have been accused of being psychic. now awaiting new camera, my birthday is on St Georges day, wont be long.
PS. Many of the pieces carry the coat of arms of Spanish regions.
