Cleaning work on Würzburg's Franconia Fountain

清洁是喷泉恢复的一部分

作为文化的一部分赞助,因为Karcher cleaned a large part of the Franconia Fountain at the Würzburg Residence. Over the decades, the hard Würzburg water had left layers of limescale millimetres thick on the figures, making it virtually impossible to see at first glance that they are made from bronze. In addition, biogenic growth had settled on the limestone elements. The cleaning operation was completed ahead of the restoration of the fountain, which will continue through to 2020.

与国有宫殿，花园和湖泊的巴伐利亚管理部门的恢复中心密切合作，策划并开展了清洁工作。要拆下Limescale的层，Kärcher清洁专家Nick Heyden使用冷水高压高达500巴。“初步详细的调查和测试表明，尽管压力，我们可以用这种方法在金属表面上轻轻地工作，”海顿说。这使得能够删除大部分LimeScale。以前，这种技术已成功地在斯图加特的宫殿喷泉上使用。

To remove the biogenic growth, Heyden worked with a hot water high-pressure cleaner in gentle steam mode with a surface pressure of 0.5 to 1 bar and a temperature of up to 100°C. This type of cleaning allows moss and lichen to be removed without high pressure or chemicals. It also delays the growth of new vegetation, as the steam's high temperature disrupts the deeper-seated spores.

下一步

"Before the cleaning, it was impossible to identify the bronze figures. We are now able to inspect them in more detail and work out how we can maintain the protective patina," explains Hannah Holland, metal restorer at the Restoration Centre of the Bavarian Administration. Various techniques are conceivable here. The use of chemicals would be irreversible, which means that coloured waxes will probably be used. "Wax can be renewed regularly and protects the bronze’s patina from new limescale formation. Coloured waxes also allow us to retouch, like in picture restoration, until the required result is achieved," says the restorer.

喷泉是巴伐利亚州丽晶王子的Luitpold的礼物，在他的70岁生日之际。它被称为“整个Frankish人民的爱情纪念碑”，作为“纪念碑弗朗西尼亚”。Residenzplatz被选为纪念碑的场地，将其放在丽晶王子的发源地旁边。整个工作包括青铜数据，是由Ferdinand Freiherr Von Miller设计的。喷泉于1894年6月3日亮相。
