We are used to stainless steel thermal flasks in the market. But do you know that some beverages are not suitable to be placed in stainless steel flask?

Common issues stainless steel thermal flask users might face:

  1. Metallic Taste

  2. Change of smell or aroma of beverages

  3. Metal Leaching


Stainless steel thermal flask can leach chemical to acidic beverages, and will stain when used for long period of time. Iron, chromium and nickel were all found to leach into both alkaline and acidic foods and beverages such as coffee, tea, citrus juice, milk and many more.

With porcelain interior, Swanz Kokoro is 100% BPA Free, free from

metal and chemical leachings. 

No More Metallic Taste and

Lingering Smell

Say no more to metallic taste in your drinks. Porcelain preserves your beverages authentic taste. Enjoy the best of your drinks.

Naturally Easy to Clean

Porcelain are made from kaolin clay and fired at temperatures as high as 2,600°F. This makes porcelain pores extremely fine, making it easy to clean and prevents any stain and smell to linger on it.

One of the popular question being asked: What is the main difference between porcelain and ceramic? The main difference is the size of surface pores. Ceramic has relatively larger pores compared to porcelain, resulting in stain might still occur in common ceramic. Which it will not happen in porcelain.

Goodbye Coffee Stain

No Peeling Off

Another common question to be asked is what is the difference between solid porcelain and ceramic coating? Ceramic coatings is only a coating, it might peel off and having the risk of peel off residues to be consumed.
