Toyo-Sasaki Kurotama Gold Foil Cold Sake Set
Toyo-Sasaki Kurotama Gold Foil Cold Sake Set
The Toyo-Sasaki Kurotama Gold Cold Sake Set brings together clear Japanese glass, deep ink-like accents, and real gold foil detailing in a refined sake set made for quiet enjoyment and elegant gifting. Made in Japan by Toyo-Sasaki, the set includes one sake carafe and two matching sake cups, offering a complete presentation for chilled sake, fruit sake, plum wine, or other cold drinks.
The design is centered around a dark “kurotama” sphere-like motif, suspended within the transparent glass like ink resting in water. Fine vertical lines run through the carafe and cups, giving the set a calm sense of rhythm, while scattered real gold foil adds a soft metallic shimmer. As light passes through the glass, the gold catches gently against the black accents, creating a look that feels understated, luxurious, and quietly ceremonial.
Each piece is made using semi-red crystal glass with a smooth, transparent finish that allows the colour of sake to remain visible. The carafe features a recessed inner chamber that can hold ice, helping keep sake chilled without diluting its flavour. This makes the set especially practical for cold sake service, allowing the drink to stay refreshing while preserving its original aroma and taste.
The sake cups are shaped with a wide, flared mouth and a stable thickened base, giving them a comfortable hold and a balanced feel on the table. The clear glass body, black linear pattern, and real gold foil details create a refined contrast that works beautifully for both modern and traditional table settings.
Presented in a wooden box, the Kurotama Gold Cold Sake Set is suitable for gifting, entertaining, or personal use. Its combination of Japanese craftsmanship, practical chilled-sake design, and real gold foil decoration makes it a thoughtful choice for sake lovers and collectors of Japanese glassware.

Product Care
MAIN TAINING
HAND WASH
To prevent damage to items, it is recommended to clean them individually using warm water and non-abrasive cleaning products. We recommend setting your dishwasher on gentle mode or washing gently by hand.
DRY AND WIPE
Place the glass on a towel or absorbent kitchen paper and blot it dry, or wipe it carefully while holding the body with your thumbs to reduce pressure. Use lint-free fine cotton or linen towels. Put the cups back into the box or stand them upright without touching each other.
STORAGE and PRESERVATION
The edges of handmade crystal wine bottles are very thin, so they should be placed in a cupboard or packaging box with the cup mouth facing upward to prevent the cup mouths from touching each other. Do not stack wine bottles or hang them with hooks to avoid cracking the handles. Wine bottles should be stored in a clean and tidy place, with the mouth of the cup facing up and the cap open for ventilation.
MAINTENANCE
Do not leave wine in the bottle. Please clean it in time after use. The decanter must be cleaned with a soft sponge in warm water. Do not use detergent. If fog appears, pour some coarse salt and half a liter of alcohol. Shake vigorously and rinse with warm water several times. Insert absorbent kitchen paper into the cup for about 10 hours to absorb residual moisture.
The crystal glass material is purely hand-blown. Occasionally small bubbles and small scratches are normal phenomena. The crystal material is not resistant to high temperatures and cannot be heated and steamed. It is not suitable for boiling water to be poured directly into it. It is only suitable for daily tea temperatures below 50~60℃.

Design
Crafting Of Edo Kiriko
The artist marks simple grid lines on the glass without drawing a design to provide the plan's framework. The design grid is drawn on the glass's surface using a bamboo stick or brush with red iron oxide. Next, the baselines of the design are lightly etched using a whetstone. Relying on these fine marks and lines, the delicate patterns of Edo kiriko are created with the artisan's expertise and skills.
First Cut
The base design is cut to about three-quarters of the final width and depth. The surface of the glass is cut using a sand paste-coated metal disc rotating at high speed. Generally, emery powder with many abrasive particles is used to create the sand paste. The clear pattern border lines and the irregular patterns are cut little by little. The balance between the thickness and depth of the cut lines relies upon the artisan's years of experience, as there are no detailed sketches.
Adjustments
The patterns cut in the second stage are adjusted, and the surface is smoothly polished in this process. A whetstone disc, natural or artificial, is used to cut delicate patterns which cannot be created with the metal disc used in the prior process. This is the last cutting stage to complete the designs, so careful work is required not to leave any powder residue and to ensure a brilliant finish.
Polishing
This is the final stage of production, and it is usually carried out on soda-lime glass (most prevalent type of glass). The opaque surface left by the third stage is returned once more to its original transparent state, with the attractive shine and sparkle typical of Edo kiriko. Chemical processing with hydrofluoric acid is also applied for high-class crystal glass. Depending on the piece, a variety of different polishing discs are used, such as paulownia wood discs, willow wood discs, hair brush discs, and belt discs. The final work is polished by applying water and polishing powders to obtain a glittering finish, while fine sections are polished with a cloth or a brush. To complete the final polishing, a cloth buffing disc is used to bring out the sparkle and shine of the cut glass.
