Why did the tall glass shade influence early 19th-century candlestick designs?

In the early 19th century, the design of candlesticks was primarily influenced by the introduction of the tall glass open shade. This functional addition was significant because it prevented the candle flame from flickering, providing a more stable and consistent light source.1

Beyond this practical innovation, candlesticks of the period were typically crafted from brass or bronze and featured Egyptian or Classical motifs. This aesthetic reflected the widespread cultural fascination known as "Egyptomania," which influenced decorative arts across the continent at the time.1
