Tea Coaster / Glass Coaster / Stained Glass

◎ A note before you buy: Please do not place an order if you cannot accept the following conditions. Solder will change as it oxidizes upon contact with air. This is especially true for the copper patina, which will transform from bright copper to antique copper, and eventually to a dark brown. Therefore, the final product will "absolutely" not look identical to the photos. We cannot control how the patina changes. If you are unable to accept the variations in copper patina due to oxidation, please request a black patina from the designer, which changes the least. Gentle reminder: When using the 10cm coasters, please place cups gently. If using a heavy mug, such as a thick ceramic mug, placing it down forcefully may break the coaster. Initially, we only sold small coasters because tea ceremony cups are placed down gently. Additionally, larger pieces of glass are more fragile. Buyers, please exercise caution during use to avoid injury. Product dimensions: Length 6cm x Width 6cm x Thickness 0.3cm, Length 10cm x Width 10cm x Thickness 0.3cm (±0.5cm) Main materials: Begonia glass, solder, hand-dyed patina Origin: Taiwan (designer's handmade) Important notes: ▴ All products in this shop are designed and handcrafted by the designer. The reclaimed vintage glass, decades old, may exhibit scratches, color spots, or bubbles due to its history and environment. Minor scratches and chips may also occur during the glass grinding process (especially noticeable on clear or mirror glass), all of which are within the normal range. ▴ The patterns and colors of the glass are unique to each piece; identical items cannot be guaranteed. Please communicate thoroughly with the designer before ordering. ▴ Solder, whether patinated or not, will develop a misty or darker appearance upon contact with air due to oxidation (especially noticeable with copper patina). ▴ Do not use for serving food. Even 99% pure solder is not food-grade tin. ▴ Some containers without drilled holes can hold water, but this will accelerate the oxidation of the solder and may produce a significant amount of white crystals. ▴ To promote environmental protection, simple packaging will be used for all shipments. ▴ For glass products, please record a video during unboxing to protect your rights. Currently, only SF Express offers compensation for damage. You may contact the designer to enable SF Express shipping for your order (delivery to residential addresses only, no pickup at convenience stores). Shipping costs for any logistics method are borne by the buyer. Care instructions: ▴ The solder surface will form an oxidation layer over time with prolonged exposure to air. This can be gently scraped away with a toothpick. For daily care, simply wipe with a dry cotton cloth. ▴ For advanced care, a thin layer of polishing wax (soft wax) can be applied to the surface. After it dries, buff to a shine with a dry cotton cloth.
