== Occurrence ==

Mentions of this type of lava can be found in 18th Century Hawaiian newspapers where it is called "Lauoho o Pele," "Lauoho Pele," and "Lauoho ehuehu a Pele."


Wind often carries the light fibers high into the air and to places several kilometers away from the vent. It is common to find strands of Pele's hair on high places like treetops, radio antennas, and electric poles.

Pele's hair does not occur only in Hawaii. It can be found near other volcanoes around the world, for example in Nicaragua ([[Masaya_Volcano|Masaya]]), Italy ([[Mount_Etna|Etna]]), Ethiopia ([[Erta_Ale|Erta’ Ale]]), and Iceland, where it is known as "nornahár" ("witches' hair").<ref name="Duffield77">{{cite journal | url=https://pubs.usgs.gov/journal/1977/vol5issue1/report.pdf | last1=Duffield | first1=W.

It is not recommended to touch Pele's hair, because it is very brittle and very sharp, and small broken pieces can enter the skin. Gloves should be worn while examining it.

== Applications ==
[[Mineral wool]] (also called stone wool or rock wool) is commonly used as a non-combustible, durable, dimensionally stable, UV stable, hydrophobic, vapor-permeable building insulation material for residential, commercial, and high rise buildings. The process of manufacturing this material uses a similar principle to the formation of Pele's hair: melting rock and recycled slag from steel manufacturing combined with high-pressure air currents. A hydrophilic version of this material can be used as a low water usage, high yield, soil substitute for hydroponic agriculture.

== Traditional beliefs ==
Pele is known as the goddess of fire, lightning, wind, dance and volcanoes. The legends that tell how Pele first came to the Hawaiian Islands have a lot of versions, but it is believed that Pele's spirit lives in the crater of the Kilauea volcano, on the island of Hawaii. Pele appears as a spirit in many forms, and she is considered a negative harbinger. Most native Hawaiians state that they have had at least one encounter with her.{{Citation needed|date=May 2017}}

Hawaiians traditionally believe that they must live in harmony with all natural things, and that Pele will curse with bad luck people who take lava rock, sand, seashells, or other natural parts of the islands away with them, until they return these items to their rightful place. Additionally, federal law prohibits taking anything out of a national park. Each year large quantities of such objects are mailed back to Hawaii by people who believe they have received such bad luck.<ref>{{cite web|url=http://mythicalrealm.com/mythical-gods-legends/pele-goddess-of-fire-hawaii/|title=Pele, Hawaii Goddess of Fire: Hawaiian Legend ⋆ Mythical Realm|date=22 August 2016}}</ref><ref>{{cite web|url=http://goddessschool.com/projects/Amaris/L1FPPele.html|title=Hawai'ian Volcano Goddess, Madame Pele|first=Grandmother|last=Moon}}</ref>

Pele's hair, with a hand lens as scale
Strands of Pele's hair under microscope view

Pele's hair (closest modern Hawaiian translation: "lauoho o Pele"[1]) is a volcanic glass formation produced from cooled lava stretched into thin strands, usually from lava fountains, lava cascades, or vigorous lava flows. It is named after Pele, the Hawaiian goddess of volcanoes.[2]

Occurrence

[edit]

Mentions of this type of lava can be found in 18th Century Hawaiian newspapers where it is called "Lauoho o Pele," "Lauoho Pele," and "Lauoho ehuehu a Pele."

Wind often carries the light fibers high into the air and to places several kilometers away from the vent. It is common to find strands of Pele's hair on high places like treetops, radio antennas, and electric poles.

Pele's hair has been produced by volcanoes around the world, for example in Nicaragua (Masaya), Italy (Etna), Ethiopia (Erta’ Ale), and Iceland, where it is known as nornahár [ˈnɔ(r)tnaˌhauːr̥] ('witches' hair').[3] It is usually found in gaps in the ground, mostly near vents, skylights, ocean entry, or in corners where Pele's hair can accumulate.

It is not recommended to touch Pele's hair, because it is very brittle and very sharp, and small broken pieces can enter the skin. Gloves should be worn while examining it.

Pele's hair may occur along with Pele's tears.[3] They indicate to volcanologists information about the eruption, such as the temperatures and the magma's path to the surface. Plagioclase starts to crystallize from the magma of Pele's hair at around 1,160 °C (about 2120 °F).[4] Also, the shape of the tears can provide an indication of the velocity of the eruption, and the bubbles of gas and particles trapped within the tears can provide information about the composition of the magma chamber.

Formation

[edit]
First description by J. Dana, 1849
Pele's hair on a pahoehoe flow at Kīlauea Volcano, Hawaiʻi, March 27, 1984

The strands are created when molten lava is ejected into the air and form tiny droplets, which elongate perfectly straight. It usually forms in lava fountains, lava cascades, and vigorous lava flows.[3]

Features

[edit]

Pele's hair has a golden yellow color and looks like human hair or dry straw. In sunlight, it has a shimmering gold color. Length varies considerably, but is typically 5 to 15 cm, and can be up to 2 m.[5] Hair diameter ranges from about 1 to 300 μm (0.001 to 0.3 mm).
