Rama, if is not a link from the internet I have not found a way to do it, I am new in this "magical" stuff of computing and learning, only David has a way to do it or like Seogsoo that has his own web page. I only do copy and paste, but not from my computer files but something that is conected in the web.

Sorry.

Regards

Zercas

HI ALL,

This is an interesting topic

The use of natural dyes is attracting growing attention. However their extraction and

processing cannot, in general, be regarded as environmentally friendly or even

environmentally benign. To dye 100 kg. leather with 2% dye requires approximately

100kg. dried leaves, equivalent to 500 to 1000kg. freshly picked leaves. Even if only

a small fraction of the leather produced were dyed with vegetable dyes, very large

plantations would be necessary. In addition, dye producing plants, with a few minor

exceptions, supply no foodstuffs or other useful by-products. The chromophore is

often present only in very small, often unknown quantities and is unevenly

distributed. The extraction process also produces a large amount of inert materials

which have to be removed from the goods or the dyebaths

Suspicion would not be sufficient market need

Here this natural dyes are not for all.

The main aim of dyeing the leather with Natural flowers and fruits is mainly as a herbal that will act as a supportive therapy to cure the diseases.

So instead of seeing the commercial aspects, we should see the types of application and how it will help the human life.

There are many places in this world that will give a quality herbal flowers.

The Plants in North Pole are having less nitrogen and pottassium , but has a grate affinity towords acidity and heat. Our study and research should be like a leather tanned with herbal and dyed with natural dyes should be used maximum to one month after which, he should buy the next leather piece tanned with herbal.

He should not use the leather for years like our shoes or foot wear.

So the tanners also tan good number of leathers that will giive life to many tannery workers.

Dear Mr.Kallenwe,

The old records in our Government departments speak volumes about herbals and how the Europians and Americans were behind them. These Westerners gave a transister radio to the Tribes at hill and took many kinds of Herbals.

You must know onething Mr.Kellenwe, in head ache there are 36 kinds. Due to air lock, due to cold, due to stress due to weather and so on.

But you take only pain killers, the side effect of which is nerves weakens.

But the herbals has no side effects.

Here I am sugessting use of herbals in Tnning., so that the leather Industry will survive and we are trying our level best in joining our hands so that the sufferers will get some mind support.

Snake oil always has sold well, and certainly stimulates the economy! Most of these guys get it in the end though.

Is snake oil mono unsaturated? Because a lot of the arguments I am seeing are highly saturated-with BS!

At least you must be able to read enough of it to figure out that it is BS. Is it in Spanish?

Definitelly not Castillian! By the way did you know that the word in English: "Gibberish"; supossedly comes from one Ibn Gabirol? A Judeo-Hispanic scholar that wrote in Arabic, mainly medical texts.
