Old Sheffield plate tall candlesticks with hurricane glass shades - Embossed with nautilus shells, scrolls and acanthi leaves - 烛台 (2) - 镀银

Stunning pair of Rococo Revival Old Sheffield plate candleholders with hurricane glass shades, dating to the Regency Period. Waisted columns with bulbous knops and shoulders are raised on fluted circular bases. Opulent hand-chased relief decoration of acanthi foliage, scrolls, stylised ribbed waves to bases and nautilus sea shells. The storm shades are made of thick glass and have an inverted bell-shape. Very monumental candlesticks standing at half a metre tall assembled and an absolutely exquisite example of English silversmithing craftsmanship. Origin: Sheffield Date: c. 1790s 6166 g 34 cm tall without shades 53 cm tall with shades 16.5 cm across the base Excellent antique condition. Copper bleeding appropriate to age and use; the top of one sconce is a bit uneven; fleabites to the lower rims of the glass shades. Sheffield Plate, now known by collectors as "Old Sheffield Plate" was accidentally invented by Thomas Boulsover, of Sheffield's Cutlers Company, in 1743. While trying to repair the handle of a customer's silver knife, he heated it too much and the silver started to melt. When he examined the damaged handle, he noticed that the silver and copper had fused together very strongly. Experiments showed that the two metals behaved as one when he tried to reshape them, even though he could clearly see two different layers. Boulsover developed the technique of sandwiching an ingot of copper between two thin plates of silver, tightly binding it with wire and then heating it in a furnace. This was then milled into sheets from which objects were made. The production of Sheffield Plate declined after 1840 when George Elkington invented electro silver plating which is why genuine Old Sheffield Plate items are so rare and highly regarded. Furthermore, electroplating tends to produce a "brilliant" surface with a hard colour – as it consists of pure rather than sterling silver and is usually deposited more thinly which causes it to lose silvering much quicker than Old Sheffield ware that still retains its beauty 250 years down the line.

一对令人惊叹的洛可可复兴式旧谢菲尔德盘形烛台,配有防飓风玻璃灯罩,可追溯到摄政时期。带有球形凸起和肩部的收腰柱子位于凹槽圆形底座上。华丽的手工雕刻浮雕装饰,包括刺叶、卷轴、底座上的风格化肋状波浪和鹦鹉螺贝壳。

防风雨帘由厚玻璃制成,呈倒钟形。

巨大的烛台高达半米,是英国银匠工艺的绝妙典范。

起源:谢菲尔德
日期:约 1790 年代

6166 克
34 厘米高(无遮光)
53 厘米高,带遮阳帘
底座直径 16.5 厘米

古董状况极佳。铜的渗色与年代和使用情况相符;一个壁灯的顶部有点不平整;玻璃灯罩的下边缘有裂痕。

谢菲尔德盘,现在被收藏家称为“老谢菲尔德盘”,是由谢菲尔德刀具公司的托马斯·博尔索弗于 1743 年偶然发明的。在试图修复一位顾客的银刀的刀柄时,他加热过度,银开始熔化。当他检查损坏的刀柄时,他注意到银和铜已经非常牢固地融合在一起。实验表明,当他试图重塑这两种金属时,它们表现得像一种金属,尽管他可以清楚地看到两个不同的层。博尔索弗发明了一种技术,将一块铜锭夹在两块薄银板之间,用金属丝紧紧地绑住,然后在炉中加热。然后将其研磨成薄片,用来制造物品。

1840 年乔治·埃尔金顿发明了电镀银之后,谢菲尔德盘的产量开始下降,这也是真正的老谢菲尔德盘产品如此稀有和备受推崇的原因。此外,电镀往往会产生“光亮”的表面和坚硬的颜色——因为它由纯银而非标准银制成,而且通常镀层更薄,这导致它的银质比老谢菲尔德器皿更快褪色,而老谢菲尔德器皿在 250 年后仍保持其美丽。
