They demonstrated their craftsmanship in rolling, edging and laser cutting and built their first stainless steel vessel themselves. The vessel shell was rolled and welded from a thin stainless steel sheet, the vessel lid was edged and fixed with rivets, and the vessel feet were mounted. In order to obtain a real unique specimen, the vessels were inscribed with the name of the respective child using a laser. During a tour of the factory, the children quickly realised that the large tanks are actually built in exactly the same way as the mini vessels. An impressive realisation in spite of the very different dimensions. Like the large tanks, which are often used in food processing plants, the small vessels were cleaned before initial operation and then filled with ice. Whether children, Roth employees or parents at home, everyone was proud of what the children had created from a few pieces of sheet metal. We had a very nice day together.
