AbstractThis paper describes the analysis of two near-spherical metallic inclusions partially incorporated within two Roman raw glass slags in order to elucidate the process that induced their formation and to determine whether their presence was related to ancient glass colouring processes. The theory of metallic scraps or powder being used in Roman times for glass-making and colouring purposes is widely accepted by the archaeological scientific community, although the assumption has been mainly based on oral traditions and documented medieval practices of glass processing. The analysis of the two inclusions, carried out by X-ray computed tomography, electrochemical analyses, and scanning electron microscopy, revealed their material composition, corrosion and internal structure. Results indicate that the two metallic bodies originated when, during the melting phase of glass, metal scraps were added to colour the material: the colloidal metal–glass system reached then a supersaturation condition and the latter ultimately induced metal expulsion and agglomeration. According to the authors’ knowledge, these two inclusions represent the first documented and studied finds directly associated with the ancient practise of adding metallic agents to colour glass, and their analysis provides clear insights into the use of metallic waste in the glass colouring process.

The seamless integration of emerging technologies in architecture negates their architectural expression. As long as emerging technologies in material processing and fabrication continue to be relegated to the lowly status of construction tools their impact on architecture will be deferred. Architecture can only express issues that are considered as design factors. In order to rein in the current trend of geometry driven design characterized by its lack of construction logics, emerging technologies in material processing and fabrication must supplant pure form among architectural design considerations. When these technologies are core drivers of design they have the potential to engender novel architectural expression and, in doing so, their potential effects become undeferred. The Barcelona Pavilion exemplified the undeferring of emerging early 20th century material and technological potential. Current emerging technologies in glass processing and fabrication will be undeferred in a reimagining of that project: The Glassroom Pavilion.

Glass is one of the most relevant high-performance materials that has the benefit of a favorable environmental footprint compared with that of other commodity materials. Despite the advantageous properties of glasses, polymers are often favored because they can be processed using scalable industrial replication techniques like injection molding (IM). Glasses are generally processed through melting, which is both energy intensive and technologically challenging. We present a process for glassworks using high-throughput IM of an amorphous silicon dioxide nanocomposite that combines established process technologies and low-energy sintering. We produce highly transparent glass using classical IM and sintering, allowing for a potentially substantial reduction in energy consumption. Our strategy merges polymer and glass processing, with substantial implications for glass utilization.
