Avventuria Clear glass with metal flecks, often copper, to create a shimmery, metallic look. The process is aptly named, as it means "adventure" describing the difficulty of working with this process.
Battuto "Beaten" Similar to inciso, but with deeper and broader cuts, can look similar to stylized fish scales.
Corroso "Corrosive" A surface treatment in which the glass is etched by dunking the finished object into a vat of Hydroflouric acid. Masks of sawdust or paraffin are used to protect areas of the work that the artist does not want affected by the acid.
Cristallo A clear, highly malleable, colorless glass that can be blown into vessels with remarkably thin walls.
Filigrana
A technique from the 1500's used to make items with an opaque white or
colored glass core. Specially designed glass rods are placed in a furnace
lengthwise and fused together. After fusion, they are blown and shaped. 
This technique has 3 additional patterns, depending on how the filaments
are twisted and aligned. With mezza-filigrana, rods with one filament
are used. a reticello is a diamond shaped pattern created by twisting
two halves of an object in opposite directions while heating, distorting
the straight lines of the filigrana rods, creating a diamond mesh pattern.
a retortoli consists of 2 filaments twisted into a spiral.
A Ghiaccio "Ice". Hot glass is submerged in cold water creating a finely crackled surface.
Incamiciato A multilayered glass technique. Colored or pasta vitrea glass is encased in a final cristallo or transparent colored layer. First developed in the 1920's.
Inciso "Incision" A thin line scored into the glass by a grinding wheel.
Inclamo Fusing together many different colored glass pieces while pliable, and then forming them into a single object.
Iridato Glass which achieves a thin iridescent coating due to the exposure to the gaseous vapors of a metal, usually tin or titanium. Other metals which form an oxide on the surface of the hot glass can also be used.
Lattimo Opaque white or colored glass.
Massiccio A technique in which large or heavy objects are created without blowing because the molten glass is too heavy and dense. The glass is shaped, molded or formed while hot.
Millefiori "A thousand flowers" Lattimo glass decorated with murrine and often encased in a layer of clear or tinted glass. One of the oldest techniques that is still very popular today.
Murrine A glass technique first developed by the Romans and rediscovered in late 1800's. Thin sections of glass rods are fused together and then blown, formed or molded into the desired shape. The rods are often designed to create a floral or geometric design. See our INSERT LINK!!!!!!!Murano Glass Pendants and Murano Glass paperweights for examples. In addition, we also have a short article on how a Millefiori Pendant is made.
Pasta Vitrea A very difficult technique to master, in which a colored, opaque glass is made by adding clear or colored crystals to molten glass.
Pennelate A design created by fusing colored pieces of glass to the surface of a hot item being blown.
Pulegoso Clear glass containing innumerable bubbles (puleghe). The bubbles are created by adding kerosene to the hot glass, creating bubbles upon combustion.
Soffiati Mouth blown glass with classic lines and delicate colors.
Sommerso A technique used to create thick layered objects by repeatedly dipping a piece into various crucibles of molten glass to form a multi- layered or multi-hued effect.
Tessere Glass created by fusing together various pieces of glass of almost random shapes and sizes and then blown or worked.
Tessuto A multicolored, often striped glass made by fusing colored rods placed together in an alternating pattern and blown.
Trasparente colorato A clear glass similar to cristallo but with an added tint or color.
Velato Treating the surface of the glass with a grinding wheel, giving it a satin finish.
