Dupioni Dupioni Dupioni (also referred to as Douppioni or Dupion) is a plain weave crisp type of silk fabric, produced by using fine thread in the warp and uneven thread reeled from two or more entangled cocoons in the weft. This creates tightly-woven yardage with a highly-lustrous surface. It is similar to shantung, but slightly thicker, heavier, and with a greater slub (cross-wise irregularity) count. Dupioni is often woven with differing colors of threads scattered through the warp and weft. This technique gives the fabric an iridescent effect, similar to but not as pronounced as shot silk taffeta. Dupioni can be
Types of volcanic eruptions Types of volcanic eruptions Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different types of eruptions. The most well-observed are magmatic eruptions, which involve the decompression of gas within magma that
