(부산=NSP통신 허아영 기자) = (도남선 앵커) = 석계 유길삼 lives and works in Dan-ha yo Yang-san Kyung-sang province.
He is a master potter who tenaciously has worked with traditional firewood kiln for more than three decades.
He has held many exhibitions in Korea as well as Japan, making people around the world know the excellency of Korean pottery.
More than a decade ago 석계 유길삼 found a new substance, 슘, in the pottery in fire 슘 is now attracting much interest.
He says that this substance is the wisdom of Korean ancestors which is made in fire more than 1300 celsius.
This conductive matter makes almost every material like fertilizer, salt, water, and alcoholic drinks better in terms of their nature, conducting its goodness to its surroundings.
What is Shum?
A test report from a university.
Neutral water with 7.0 ph is poured into a glass coated with shum.
After that ph indicator shows a wonderful result.
Water touching the glass indicates 8.6ph, water one centimeter inside the glass shows 8.4ph and center of the glass 7.5ph.
The water immediately becomes alkaline.
Red wine and soju show the same result.
When red wine with 6.0ph and soju with 6.5ph are poured into the glass respectively, ph levels of them increase in no time.
The quantity of essential minerals also increase.
Same result comes with bowls.
A document from a laboratory of Korean fertilizer manufacturer.
The sugar content of a shum-treated matured tomato is tested.
The sugar content of a matured tomato treated with shum once shows 0.3, second 0.4, third 1.1 and fourth 1.6. The gap is very large.
Now weight is tested
The weight of the treated tomato is 2.82 gram heavier.
During the initial experiment, this new substance shows effect on strawberries, rice, red peppers, and tomatoes, but now as the number of farmers using this increases, it also gives excellent effect on almost every produce like apples, blueberries, grapes.
Shum is made through special process after clay is heated with 1300 celsius degree and ground into fine dust. The institution says that shum has abundant natural minerals.
Far infrared radiation from shum detoxifies the inside of produce, activates metabolism of them and enables them to absorb balanced nutrients, increasing sugar contents and boosting growth.
Here's Kim doo-ok who ran a company whose products was a way to improve the polluted environment with microbes
Once she dreamed to purify polluted rivers around Busan with these microbes but a year ago she happened to conduct a experiment in which she raised mudfish in a shum-treated concrete container filled with dirty water from the most polluted Dea-ri river in Busan.
The result was surprising. She expected the mudfish would immediately die just after they were put into the dirty water but they survive for more than a year.
Though some feeds were given, the container was refilled with the river water so the mudfish were supposed to die at once.
The water is too polluted for any fish to live for more than a few minutes.
This matter efficiently makes the very nature of things like water, fertilizer, and every conductible substances better.
With shum ordinary wine becomes high quality one as it enhances the taste and scent. Now time is ticking for it to become widely known with a paper by a university professor.
If concrete dam can purify water, if skin touching clothes and bed clothes make people healthier, if PETs purify soil instead of polluting
These ifs are among the future assignments for shum found by 유길삼 who is selected as this year's New Knowledge Worker of Korea
