HISTORY OF LATEX:

One-hundred
seventeen-years ago the domestication of the rubber tree took place.
Brazil provided the world with the rubber tree, Hevea Brasiliensis,
but that country no longer plays any significant part in the world
NR (natural rubber) trade. In 1873 seeds were exported from the
lower Amazon area of Brazil to London UK by Henry Wickham, a local
planter acting for the British Government.
The seeds were
germinated at the Tropical Herbarium in Kew Gardens, London and sent
to India but died. In 1876 2800 more seedlings were exported to
Ceylon (Now Sri Sanka) where they grew strongly, and the technique
of tapping was developed. Once established outside its native
country it was propagated in all British Colonies. By 1898 a rubber
plantation had been established in Malaysia and today most
plantations are in Southeast Asia with some in Tropical Africa.
By 1900, most of the techniques and agricultural practices required
to establish large plantations had been developed. One key technique
was dud grafting. This is essentially a cloning technique which
ensures that genetically identical trees can be produced in
unlimited numbers.
Simultaneously, local farmers saw the opportunities of rubber
cultivation, and planted small groves of trees to supplement their
own income.
This gives rise to two types of rubber plantations in most producing
countries: the estates, or plantations and the smallholdings.
Estates are essentially large-scale farms, with professional
management. Most latex comes from professionally managed estates.
Latex Is Not Made From Sap
Latex is often described as the sap of the Hevea tree. This is not
an accurate description. The sap runs deeper inside the tree,
beneath the cambium. Latex runs in the latex ducts which are in a
layer immediately outside the cambium. This highlights the skill of
the tapper. If the cambium is cut, then the tree is damaged, because
the cambium is where all the growth takes place.
Methods Of Latex Rubber Tapping

All
natural rubber originates in the Hevea tree, and it starts its
journey when the tree is tapped. Trees are rarely tapped more often
than once every two days.
A tapper starts the trek around the plantation before dawn. At each
tree a sharp knife is used to shave off the thinnest possible layer
from the intact section of bark. (The cut must be neither too deep,
nor too thick. Either will reduce the productive life of the tree.)
This starts the latex flowing, and the tapper leaves a little cup
underneath the cut. He returns later that night and collects the
cup.
Processing Of Latex
After the latex is gathered on the tapper's return journey it is
then poured into containers and delivered to a processing station
where is is strained, heated and concentrated. At the end of this
process the latex is washed of all proteins that could cause
allergies.
Environmental Conservation
When latex production tends to diminish and the tree is so tall its
heavy crown is often damaged (between 30 and 35 years) the rubber
trees are cut down and replaced with new stock. The tree is then
used for wood and other uses.

sure you look for the
Talalay latex made in the U.S.A. to be sure
you are purchasing the finest quality latex in the world.
