After the glass glaze was opened, no one had already burned pottery without sprinkling it with a mixture of sand and ash.

    The potters did not yet know that it was not the ash itself that was important, but the soda, potash, and niter present in the ash. These substances together with sand formed a new substance. Now we call it glass glaze.

    It often happened that the glaze itself was stained in any color: red or purple, blue or green.

    Glazed dishes had great advantages over unglazed. The edges of the cups became smooth, as if polished. It was more pleasant to drink from such cups. And, besides, it showed one very important advantage: it turned out that a shiny crust retains moisture. In such a jug, you can store water or wine for a long time and transfer them from place to place.

    Centuries passed. Elegant glass glaze on clay vessels was no longer surprising anyone. People learned how to get a soda from soda lakes and used it to make a glaze.

    But in the new generation, a new inventor appeared. Looking at the smooth shiny glaze covering the clay like thin armor, he thought: “Is it possible to make a thing out of it alone?”

    And this brave man has betrayed the rules of his fathers. Instead of sprinkling jugs with a mixture of sand and soda, he prepared more of this mixture, put it in a separate pot and put it in a fire.

    When the mixture melted, he caught a little sticky liquid with a clay stick and threw it on a stone. Soon on the stone lay a poured shiny drop - the first glass product on earth!

    It is difficult for us to imagine what feelings and thoughts owned the first glassmaker when this miracle happened before his eyes. It was created by his hands. From the simple crude materials of nature, something new arose.
