Makes tap water tasty!

Enjoy clean drinking water everywhere and all the time from now on with the drinking bottle eau good by Black+Blum. The active charcoal stick inside the bottle makes this possible.

The Binchotan active charcoal has been used in Japan since the 17th century as a purifying method for water as it reduces the chlorine content, mineralises the water and ensures a neutral pH value.

The Binchotan active charcoal can be effective for up to six months and is then recycled in different ways or even remanufactured. Both Black + Blum founders Dan Black and Martin Black sent a clear message about environmental protection with eau good:

“Worldwide more than 22 billion plastic water bottles are thrown away as rubbish every year.
We want to reduce this by offering a product which improves the taste of tap water and so encourages the consumer to buy less mineral water in bottles.”
The history of Binchotan active charcoal?

Its origin cannot be specifically proven however it is presumed that a form of Binchotan active charcoal (sometimes also called ‘white charcoal’) was introduced to Japan by a Japanese monk and scholar named Kukai 1200 years ago.
During the Japanese Edo period (17th century) it was widely spread by a man called Binchuya Chozaemon. How is Binchotan active charcoal produced?

First of all sustainably grown timber is laid down for some time in a kiln at a relatively low temperature; then towards the end of the process, the oven temperature is raised to about 1000 °C so that the wood glows red.
Then the charcoal is taken out and quickly covered with a special powder consisting of earth, sand and ashes; so that the charcoal surface gets a whitish colouration (which explains the name ‘white charcoal’). The rapid increase in temperature, followed by a fast cooling down leads to the bark burning and leaves behind a smooth hard surface. There is a clear metallic sound when it is beaten. How does the charcoal work?

The Binchotan charcoal has an indescribably porous surface with tiny pores which face in many different directions. Only 1 gramme has a surface of over 500 m² (about one-tenth of the size of a football field). It is also known as active charcoal as pollutant ions are absorbed by the carbon surface.

The active charcoal also has the property of setting free minerals such as calcium, iron and magnesium in water, these have health promoting properties and improve the taste of the water.
How long does it last? When you use your Binchotan active charcoal with our eau good bottle and fill it once a day it should last three months. Then you can recycle it by boiling it in water for 10 minutes and drying it in the sun.

This recycling should ensure a further three months use. Which other uses does Binchotan active charcoal have?

If your Binchotan active charcoal has been used as a water filter then it is still usable in many ways.

If you crumble it and scatter it on your house plants it will give the soil nutrients which benefit plant growth. Due to its porous surface it can also be used as a deodorant, to absorb unpleasant smells in cat litter, laundry baskets, nappy containers or shoes. Binchotan is also an effective humidity absorber and can absorb any humidity in a wardrobe. Binchotan also has numerous properties which promote good health. It not only diffuses ‘dangerous’ electro-magnetic waves from computer screens but also creates negative ions. More precisely, the infrared rays constantly emitted by the charcoal reduce the humidity in fine particles which naturally change into negative ions.
Use and care Only use tap water with the Binchotan active charcoal. Your Binchotan active charcoal has already been washed and is ready to use. Please do not wash it with solvents or soap. Please do not wash it with aromatised tonics or juices. Please take the charcoal out of the bottle you are using it in before washing it. The impurities absorbed by the Binchotan active charcoal are freed by dousing it with boiling water. Do not drink water which has been in contact with the Binchotan active charcoal for more than 48 hours. You occasionally find tiny particles / fragments of the active charcoal in the water, but that isn’t a ground for concern; swallowing them isn’t harmful (active charcoal tablets are prescribed to treat diarrhoea, digestive problems or wind).
