Safety Guidelines

Like with all products involving glass and hot water, we want you to be safe when using our products. Before using, please make sure you read the instructions below.

Ukiyo Lifestyle (the Company) shall be under no liability if the defect or failure, in the reasonable opinion of the Company, arises from wilful damage or misuse, negligence by the customer or any third party, failure to follow the Company’s instructions, or alteration or repair of the goods without the company’s prior approval.

Caution! The bottle may be hot and may burn you if you touch it when it is hot. If the bottle breaks, the glass may injure you, so carefully clean up any broken glass using gloves and a broom. Do not touch broken glass with your bare hands.

Ukiyo Sense is not responsible in any way for the misuse of products going against the following guidelines:

DO NOT pour boiling water IMMEDIATELY into the bottle. This will make sure that the glass does not overheat beyond the temperature of 
90 degrees Celsius (or 194 degrees Fahrenheit). After you boil hot water, wait for at least 3-5 minutes before pouring into the glass bottle and closing the lead.

If the ambient temperature is low, warming up the bottle before use will help the bottle last longer. This will also help the liquid to steep more effectively as the water will not lose heat when poured into the bottle.

When borosilicate glass is exposed to a sudden change of temperature of approximately 95-99
°C (205-210°F), it is susceptible to fracturing, breaking, shattering, or exploding. Glass is less likely to break or shatter if you warm it up gradually. Once you have poured in the boiling water, avoid resting your bottle on cold surfaces. Instead, rest your bottle on a trivet or kitchen towel.

Be careful when touching the top glass when hot. When opening, make sure that all the liquids at the top have moved down to the bottom part. To do this, tilt the bottle at a 45° angle.

Never place into high-temperature heaters such as microwave ovens, sterilisation cabinets, ovens or open flames. Keep away from sources of electricity.

Glass products are fragile, please handle with care. Do not drop, scratch or brush with sharp objects. 
clean your bottle thoroughly after each use. Hand-washing only.

Do not use with dry ice or any carbonated liquids or materials. Their gas can increase the pressure, causing leaks or breaking the bottle.

Keep away from children under 15 years old, due to the danger of hot liquids and glass handling.

When it has cooled down, make sure you clean the bottle thoroughly after every use and that every part is dry. Hand-washing only.

Ukiyo Lifestyle is not responsible for any misuse that goes against the guidelines listed above.
