As in other cases, In
have recovered various constituents of the mold, three of which relate to funds, introducing concentric circles, and other flat pieces are aimed at the sides (Sternini, 1995, 92, Amrein and Nenna, 2006, 495 s., Figs. 3 -4).

All these patterns have a similar feature: the party with the decorative motif appears Raised to the plane of the matrix itself, since it should be possible to attach the other parts of the mold for the wall, which could be wood or stone, they made up a cubic space, which would blow the hot glass mass obtained in part the bottle prism, stamped at the bottom of the motive clause would cast.

The neck, rim and handle would be developed later (Sternini, 1995, Fig 135).

According to recent interpretations (Amrein and Nenna, 2006, 491), several possibilities exist for the development of these vessels, the mold may consist of five elements, four wall pieces, which usually present bevel side to be fitted two to two , which would be mounted on the bottom part, which in turn provides a recessed perimeter zone to allow such placement.

Similarly, the walls could be formed by a single mold, which recess encastraría on the perimeter which often shows the mold base.

Finally, it could work with a single mold for the walls, in whose inner space encastraría the bottom, which is not in this case, the center wheels, may be the ultimate solution that was chosen for our part, in the case of is really present






a single plane, not recessed perimeter zone.

Finally, given the limited knowledge we have about the master glassmakers of antiquity, we can not fail to note the finding in Linz (Austria) two bottles of rectangular section, type Isings 90 with the bases decorated with concentric circles and two Entries (Sentia Secunda and felt secondary facit facit Aquileiae Aq vitro) that refer to a stained glass artisan would be working in Aquileia, Italy.

This name can also add that of C. Salvius Gratus, it appears, also, as a mark in some prismatic bottles located in the Po valley, natural area of expansion of Aquileia (Calvi, 1968, 13).

This is further evidence pointing to the presence in this city of glass workshops, in addition to a long list of Westerners who have offices dedicated to the development of these popular bottles are common to all regions of the Empire.

The bottle prismatic (type Isings 50)

This vessel was, as noted, one of the most common during the first two centuries of our era.

The glass is usually thick, bluish-green color and good quality.

Appear towards the second third of the century, continuing until the late second century AD, while in the Eastern Empire, these bottles, which were introduced from the western provinces in the second half of the century, remain in use until the following century .

The wall thickness and strength of the handles, with great stability, made them ideal for storage and






transport of liquids, according to the audience, being protected by wrapping wicker (Caldera de Castro, 1994 - 95, 119).

Technically, they were made by blowing open or, as we have discussed, with the aid of molds, showing them several decorations stamped on the bottom, which has been associated with brands of the workshops that produced (Foy and Nenna, 2006, 7 sec.)

Thus, we find that reference marks to epigraphic home workshop or the name of glassmaking (see above).

In other cases, the marks consist of simple geometric patterns of varying complexity, vegetables or figurative, which, likewise, might be used to identify the contents of the container, constituting, in any case, a definitive method to determine the establishment workshops, the dispersion of the products and, therefore, trade relations between the different parts of the Empire (Caldera de Castro, 1994-95, 120).

On the bottoms of the bottles documented in the Iberian Peninsula shows a wide range of figurative motifs and animals in motion, busts of gods and compositions with palms, whose dispersion can set peninsular origin also epigraphic certain brands in a circle or surrounded by a plant crowns are specific to southern regions, which may highlight the letters "LIT" or "LLF", probably from workshops located in the west or south of the peninsula (Price, 2006, 284, Fig 7; da Cruz, 2006, Fig 5 .)
