Javier Mercado teaches sugary art. To support him in his work, KFN recently sponsored the calcium oxide he works with. Confectioners use it as a drying agent. While it dries the surrounding air, it is not part of the sugary art. Sugar sculptures are 100 per cent sugar, boiled with water at 170 °C. Once heated up, the material is brought into the desired form. Only then calcium oxide is put to use: to keep the sugary art dry it is of paramount importance.
