Yavuz Eroğlu-pagev 1. Vice President, SEM plastic general manager

Poet-writer Sunay Akın underlined in Pagev Iftarında, “Ezezfen” meaning the word “ 100 experts in science “ concept came to be very interesting. I couldn't stop thinking about how a person could specialize in such matters, how he could have mastered such details. Then today, I thought about the depth and detail of every job and knowledge.…

Every business is a specialty. It is essential to love every job with passion and to go down to the details to achieve success.

For the first time in Turkey, we produce plastic Crystal Glass made by our company and design in our factories located in Istanbul and Malatya.

Crystal glasses produced are tested for many quality tests after each production Party and quality certificates related to each lot are approved-archived and stored in the archive samples of each party.

One of the tests carried out is to determine whether the cups are resistant to heat and whether they are softened or deformed due to hot water. For this purpose, a separate test procedure is applied and a glass of boiling water is observed. For this test, water is boiled and boiling water is poured into the glass, the glass's length or shrinkage, bending, etc. shape change is measured and observed.

10 years ago, we had an interesting experience. At that time, we received from a large European raw material supplier, our raw material was manufactured in Malatya plants and the final product was put on the market after a series of tests. After a while, customer complaints started to be received from our sales team. Customer complaints are mainly from customers in Istanbul, Izmir and Antalya, and customers in other provinces did not complain.

We discussed the matter with the sales team immediately meeting the emergency agenda. First of all, quality certificates belonging to the production lots and recorded production records were examined. As a result of our investigation, we found that the products passed all tests. How is it that the heat-tested products in the factory become deformed under hot conditions when they reached customers ? First of all, we asked the Malatya factory quality team to test the samples taken from that lot again to check the accuracy of the tests. The result was interesting. The glasses were warm!! Interestingly, when we tested the products that we received from the customers that we received from the customers in our Istanbul plant, we found that they were subjected to heat. The customers were right. But our factory insisted on the results of the test.

At the end of the two hard days, sleepless and questioning each step, the solution was found. We skipped the simplest physics rule. Although water boiled at 100 degrees at sea level, it was at lower temperatures at places higher than sea level. Therefore, the water in Malatya at 1,100 meters high from the sea is boiling at 100 degrees lower, and with the result of the test conducted with water at low temperatures, Glass was eaten because the water of consumers in Istanbul, Antalya, Izmir cities at sea level was boiling at 100 degrees.

We immediately withdrawn the goods sold to all sea-level provinces from the market. The problem was solved.

So what happened to the glasses that were produced before ?

We solved the problem by giving these glasses to high-rise cities and airline customers.

We received a complaint from a very prestigious large European airline client. The complaint was that the lemon drinks that airline customers drank during the trip had a sour taste in the glass we produced, and therefore the glass spoils the natural taste of the drink. That was interesting...

We tried with our team on the customer complaint immediately. As a result, we found out that this is not the case. When we went into some detail, we realized that the tastes of lemon drinks were more sour than the people in the plane.

However, this was not about our product. As a matter of fact, the glass glass served in business class served in a glass glass with Lemon, the normal daily drink of lemonade more sour taste came with.

Of course we didn't leave the subject like this, when we went into a little more detail, we saw that we were taking 20% of the taste with our tongue and 80% with our nose. In addition, the perception and expectation that our brain created with Taste had an effect on the taste of food.

The pressure difference is the difference in air and ground. When the plane is in the air cabin pressure is lower than the ground. It is the low air humidity, which corresponds to 15% of the passengers felt when flying in the air, and the air pressure of 2,500 meters above sea level. We feel under pressure on a mountain of 2,500 meters high. The taste of sugar and salt is felt less at low pressure. For this reason, the meals eaten on the plane, 20%-30% more salt and 15%-20% more sugar-free taste than the ground gives the feeling. For this reason, the companies preparing the plane dinner, 20% to 30% more salt and 15% to 20% more sugar than the ones on the ground.

In a striking example, it relates to tomato juice. If you notice that the highest amount of tomato juice consumed are the media planes. The taste of tomato juice on the plane is more delicious than the one on the ground. In this regard, the plane tomato juice in general, fresh fruit and round (degustator) taste can be said to have. The reason for this is that fruit flavours are easier to reveal at low pressure. So, considering that 80% of the taste originates from the smell, it turns out that the tomato juice consumed on the plane gives a more delicious taste.

As in the two very small examples above, no work is simple. When you enter each job detail, it requires expertise, experience and knowledge. Accumulation is sometimes gained by training us, sometimes by seeing in the work, and sometimes by experiencing ourselves in the experience. The most beautiful experience is of course the one earned by training and seeing. Because the experience gained by ourselves by experimenting and living is not cheap.

In the villages of Anatolia that spend the winter under snow, on snow roads that come almost to the waist of children, the adults walk the way in advance to find the way to the school, and the tiny students reach their schools from the path through the white cover that covers all places.

We owe our thanks to all our seniors who have contributed to our sector's development today, carried out many expensive experiences on our behalf and passed on to US, increased our belief that we will achieve with success, and left a trail on the snow.
