Serax Amber Zuma Tumblers - Brown

Hand washing is strongly recommended to preserve the graduated amber tint and the overall finish of the glass. Dishwasher use may lead to fading or damage.

These tumblers are best suited for cold or room temperature beverages. While glass can withstand some heat, sudden extreme temperature changes (like pouring boiling water into a cold glass) can cause thermal shock and potentially crack the glass.

It means the color is applied in a way that it is more concentrated at one end (in this case, the base) and fades towards the other, creating a smooth transition of color.

The description mentions an injection of amber-pigmented mass in between two transparent layers, suggesting the color is integrated within the glass structure for depth and durability.

Specific dimensions are not provided in the product information, but they are described as 'tumblers', typically indicating a standard size for drinking glasses.

Store them in a dry place, upright or inverted, ensuring they are not stacked in a way that could cause scratching or chipping. Allow ample space between them.

This is likely due to hard water deposits. Try washing with distilled water or adding a small amount of vinegar to your wash water, then rinse thoroughly and dry immediately with a soft cloth.

Ensure you are hand washing with mild soap and avoiding abrasive cleaners or prolonged soaking, which can degrade the pigment over time.

Slight variations in glass or color concentration are inherent to the handcrafted nature of such items and add to their unique character. If significant flaws are present, contact customer support.
