Hemimorphite

== Description ==
A white ore composed of hydrous zinc silicate. Hemimorphite is a minor ore of zinc that occurs in zinc mines worldwide with significant deposits in Siberia, Romania, Sardinia, Slovenia, Belgium (Vieille Montagne), Germany (Aachen), Poland (Silesia), England (Derbyshire), Mexico (Durango), and the U.S. (Montana, New Jersey, Colorado, Pennsylvania). Until the mid 18th century, the name calamine was used for both zinc silicate and zinc carbonate (smithsonite) minerals since they are similar in appearance and often occur in the same rock. Once they were recognized as two distinct minerals and assigned separate names, the name calamine was retained to designate their admixtures. Hemimorphite was also called electric calamine in the U.S.

Hemlock

== Description ==
Any of several evergreen conifer trees of the genus Tsuga. Hemlock trees are native to North America and Asia. These softwood trees produce a timber that is stiff and splinters easily. The light yellow wood is primarily used for paper pulp, boxes, and crates. The bark extract from the eastern hemlock, T. canadensis, and western hemlock, T. heterophylla, trees is high in tannins containing up to 22%. The extract is also used as a dye to produce colors ranging from a pinkish tan to a dark gray. Native Americans used hemlock to dye basketry and blankets.
== Synonyms and Related Terms ==
eastern hemlock (Tsuga canadensis -also called Canadian hemlock and hemlock spruce); western hemlock (Tsuga heterophylla -also called hemlock fir and Prince Albert's fir); European hemlock (Conium maculatum -also called poisonous hemlock); Japanese hemlock (Tsuga diversifolia); Siebold's hemlock (Tsuga sieboldii); pruche du Canada (Fr.); spruce pine
== Physical and Chemical Properties==
* Height = medium to large trees (10-60m) with branches stemming in flattened sprays
* Bark = gray to brown with deep furrows that scale
* Leaves = flattened needles (5-35 mm long, 1-3 mm wide). Occur spirally on stem, but lie flat on the stem (Wikipedia )
* Cones = oblong cylinders (15-40 mm long) Seeds are small and winged.

Hemlock bark

== Description ==
The bark extract from the eastern hemlock, Tsuga canadensis, and western hemlock, Tsuga heterophylla, contains up to 22% tannins. The extract, however, contains very little sugar for fermentation so organic acids generally need to be added to the tanning bath. Hemlock bark was an important vegetable tanning material in North America for many years producing the characteristic red leather of 19th century America (Roberts and Etherington 1982). The extract was also used as a dye to produce colors ranging from a pinkish tan to a dark gray. Native Americans used hemlock to dye basketry and blankets. Hemlock dye has fair lightfastness and good washfastness.

Henna

== Description ==
A reddish-orange dyestuff that comes from the leaves of small evergreen trees, Lawsonia inermis or Lawsonia alba, native to the Middle East, northern Africa and Asia. Henna was used by the ancient Egyptians and Asians for dyeing hair, nails, skin, leather, wool, and silk. Henna-dyed cloth was sometimes used for mummy wrappings.

Herbicide

== Description ==
A chemical used to kill or inhibit the growth of plants, especially weeds. Historically, sea salts, waste manufacturing products, and oils were used as weed killers. In the late 19th century, additional materials such as carbon disulfide, borax, pyridine, mercurials, and arsenic trioxide were used to target weeds. By 1945, synthetic organic herbicides were developed which required very low dosage treatments. Weed killers are categorized as preplant, preemergence, and postemergence. Examples include amitrole, picloram, 2,4-D, DDT, atrazine, glyphosate, diquat, and paraquat. Many herbicides do not decompose and have created long-term hazards to the environment.

== Description ==
A golden brown to red color gemstone composed of calcium aluminum silicate with a small portion of iron. Hessonite resembles yellow zircon in color and both were called hyacinth in ancient times because they were found in the same gem-bearing gravels of Ceylon. Hessonite is softer than quartz and less brittle than zircon and hence, was used in ancient engraved gems (Ogden 1982).
