From the last meeting, I got this beautiful insulator made by Fidenza in the year 1959 with the BORAL trademark!

The name BORAL comes from the words "boro" and "alluminio", because this type of hard glass contains boron and aluminium oxides as two of the principal components. In this way, Fidenza has developed a good alternative to the Pyrex glass, increasing the competition against the MIVA manufacturer.

Obviously, BORAL is not a MIVA trademark... as also shown in old Fidenza catalogues and advertisements!

Thanks to my friends for this fantastic insulator!
