Discovery of the oldest glass furnaces Israel near Mount Carmel


glassmaking furnaces dating back to the late Roman era were discovered at the foot of Mount Carmel, between junctions Ha-Amakim and Yagur, announced Monday the Israeli Antiquities Authority (IAA). This archaeological discovery is further evidence of the place occupied by the Israeli glass industry on the international stage.

Israel, a major glass production center

Furnaces glass splinters, discovered during excavations carried out in the framework of a railway project underway in the Jezreel Valley, prove that Israel was indeed a leading glass production centers of the ancient world .


"This is a very important discovery with implications for the history of the glass industry both in Israel and in the entire ancient world," says Yael Gorin-Rosen, chief curator of the department glassware in the AIA. He added: "We know from historical sources dating back to the Roman era that the Acre Valley was famous for the excellent quality of its sand, particularly suitable for the manufacture of glass. Chemical analyzes of glass utensils from this period discovered in European sites and wrecks of sunken ships in the Mediterranean region have proved that the glass is rooted in our region. Now, furnaces have been discovered, for the first time, where the raw material used to manufacture the glassware was produced. "


The extraordinary results of these almost accidental excavations have attracted glass experts worldwide. "This sensational discovery is of great interest for the understanding of all the glass trade system in antiquity. Here we have evidence that Israel was a production center of international importance; his drink was widely distributed in Europe and all the Mediterranean countries, "says Professor Ian Freestone of the University College London, an expert in the identification of the chemical composition of the glass.

The site was located by Abdel Salam Al-Sa'id, an inspector of AIA who oversaw the construction of the new railway line linking Haifa to the east. The archaeologist, whose task is to ensure that the work does not affect sites that may have historical significance, discovered pieces of raw glass, antique stalls and a layer of ash in a trench. "We also found pieces of glazed bricks from the walls and ceiling of the oven," says the director of excavations.

Industrial production for a growing market


Furnaces included two compartments: a combustion chamber where burning kindling to obtain a very high temperature, and a melting chamber in which the raw materials (the pure sand and salt) were inserted and then fused to a temperature of about 1200 Co. The glass was then heated for one to two weeks, until huge pieces of raw glass are formed. Some weighed over 10 tons. At the end of the production process, the ovens were cooled and the glass pieces were broken into smaller pieces and sold to workshops where they were re-melted to produce glassware.

The use of glass has largely developed in early Roman times, because of its characteristics very popular: its transparency, beauty, delicacy and manufactured utensils and speed production blow. Become a necessity in every home of the Roman Empire, glass was produced in industrial quantities in specialized centers. The site discovered in the Zvoulon Valley is an excellent example of such glass manufacturing centers.

Remember also that the edict of Maximum, issued 301 of the vulgar era by the Roman emperor Diocletian, mentions two types of glass: the first known under the name Judea glass (that is to say, the Land of Israel) and the second glass of Alexandria (Egypt). The glass Judea was light green and cheaper than Egyptian glass. This discovery now allows to locate one of the centers where this had occurred prized commodity in the Roman Empire.

The ovens will be transferred to the regional school "Carmel Zvoulon" and exposed to the public in a few months.

AGC Glass Europe to refurbish its Cuneo float plant (Italy) in 2017


AGC Glass Europe has planned to carry out the refurbishment of its Cuneo float glass line in Cuneo (Piemont, Italy). This investment of around 25 million euros is decided not only by the positive impact that it will have on the productivity of the plant and the expected environmental benefits, but also by the prospect of extending its current range of products.

The refurbishment including design improvements will significantly boost the plant’s capacity and reduce its energy consumption, with a corresponding positive impact on its yield and product quality. The reduced energy consumption will also mean a large reduction in atmospheric emissions, with 50% less CO (carbon monoxide), 14% less CO2 (carbon dioxide) and 30% less NOx (nitrogen oxides). This improved environmental performance in turn will make the plant eligible for the energy certification system operated by the Italian government, with subsidies granted over a period of five years in proportion to the energy savings achieved.

Together with the future gains expected from the cogeneration project, these developments will significantly boost the competitiveness of the Cuneo plant.
