European Antique Glass (Green / 70mm Height) | ADHOC Selection

"Green Light, Holding Time." - A Quiet Elegance Residing in 100-Year-Old Glass

Product Description:
A small green glass cup born in an old European workshop. Standing at just 70mm tall, this vessel retains the essence of the hand-blown technique of its time. The slightly varying thickness of the rim, naturally formed air bubbles, and a soft green glow. It possesses a warmth not found in industrial products, fitting perfectly in the palm of your hand. Simply by pouring water, it reveals a transparency and shade as if scooping from a forest spring. Beyond being a cup, it also shines as a mini flower vase or a candle holder. Each piece has a unique expression, allowing you to discover new beauty with every glance. (R070162)

Special Notes:
There are several differences in ease of processing and properties between colored glass and colorless glass. Colorless glass is essentially pure soda-lime glass with impurities like iron oxide removed. Colored glass, on the other hand, has a more complex composition due to the addition of metal oxides (e.g., chromium oxide, copper oxide, cobalt oxide). This results in changes to the melting point and viscosity, which can make processing timing difficult. Some colorants (metal oxides) can make the glass more prone to cracking during cooling or make it difficult to achieve a uniform color. Especially with dark colors (green, blue, purple, etc.), the appearance of the color can change depending on the thickness, so attention to shape is also required. Additionally, there can be slight differences in heat resistance and expansion rates, so caution is needed when mixing or welding with colorless glass. Due to reasons such as "more prone to color variation, altered viscosity, and fragility," colored glass can be considered a material for advanced glass artisans compared to colorless glass.
