Hazel

== Description ==
A small deciduous tree or large shrub (Corylus avellana, Corylus americana or Corylus maxima) native to the northern hemisphere. Hazel trees are grown ornamentally and for their nuts.

Heat-resistant glass

== Description ==
Glass that is dimensionally stable during large heat fluctuations. Four types of heat-resistant glass are: borosilicate, alumina glass, alkaline-free silica and quartz. Borosilicate glass typically contains silica (81%), boric oxide (13%), soda (4%) with some alumina. It has a very low thermal expansion coefficient and a high softening point (600C). Examples of borosilicate glass are Pyrex®, Duran and Kimax. Alkaline-free silica glass also has high thermal resistance. A normal glass mixture is softened then leached in an acid bath to remove alkalis followed by heating to 1100C to fill voids. This produces a hard glass, such as Vicor, that can be used up to 870C. Quartz glass, or pure fused silica, also provides excellent thermal stability.

Heather

== Description ==
A small flowering evergreen shrub, Calluna vulgaris, common in western Europe. Heather has been used for dying textiles in Scotland since the 18th century. It contains quercetin and myricetin colors along with some tannins in the woody stems. Heather produces a pink color in unmordanted wool. A yellowish orange color is obtained using alum or tin as mordants while copper and chrome produce brown colors. An iron mordant in wool produces a dark green. The colors are slightly fugitive. Heather stems were also used to make brooms, brushes, and baskets.

Helium

== Description ==
An inert, noble gas element. Helium is a colorless, odorless gas that is much lighter than air. In 1868, the spectrum for helium was identified in the sun's corona during an eclipse by Lockyer and Frankland. Helium was isolated in 1890 by Hillebrand and identified by Ramsay in 1895 in the mineral cleveite. Helium has been used in dirigibles and balloons for elevation and is preferred over hydrogen because it is noncombustible. It is also used for cryogenics, leak detection, geological dating, luminous signs, lasers, and as an oxygen diluent in deep sea diving tanks. Although helium is naturally produced by the disintegration of radioactive element, it is anticipated that helium reserves will be depleted by the end of the 21st century.

Hematoxylin

== Description ==
A red crystalline component that is the coloring agent in logwood dye. Logwood dye, or hematoxylon, is contained in the heartwood of the tree. The blood red extract is obtained by boiling the chips in water. It contains about 10% of the colorant hematoxylin along with resins and tannins. Hematoxylin oxidizes to form the reddish-brown metallic crystals of hematein that are insoluble in water. Using a variety of mordants, the extract can be prepared as a lake ranging in color from red to brown to navy (chrome), violet (alum) to black (iron). Logwood was used in black inks (iron gall ink and bichromate ink) and watercolors. It is still used to dye textiles and leather black. Hematoxylin is also used as a histological stain in the preparation of organic tissues for microscopic examination.
