I can answer immediately: ceramic thermos cup.
Stainless steel thermos cup is undoubtedly the mainstream of the market.
Most of the thermos cups on the market are stainless steel inner tubes, but the quality of stainless steel inner tubes for thermos cups needs to be guaranteed. The mainstream of the thermos cup is 304 stainless steel, but occasionally unscrupulous businesses use 201 stainless steel as 304. 201 Stainless steel is industrial stainless steel, acid and alkali resistance is not strong, mainly used in decoration materials, watch shell, watch band, steel pipe. If used in a thermos cup, it can harm human health.
So if you want to choose a safe thermos cup is not without solution! Kyocera's ceramic thermos uses an exclusive ceramic coated inner liner that is safe and lightweight. Can meet your thermos cup everything \"ideal\".
The two materials are healthy and environmentally friendly materials, but relatively speaking, the ceramic cup is more environmentally friendly and more natural, and if it is used to make tea or drink coffee, it is more emotional, and there is a strong light earthen ceramic fragrance.
Stainless steel thermos works best.
But ceramic cups and stainless steel have advantages and disadvantages, ceramic cups do not have those metal or other bad taste, but easy to break; Stainless steel is strong but sometimes grime and smell unpleasant.
Ceramic is better.
Ceramic is a completely harmless material, so many kitchen supplies such as ceramic kitchenware are used this material. In general, there will be some safety risks in metal thermos cups and plastic thermos cups, and long-term use has the risk of ingestion of poor metal substances. Ceramic thermos cups are completely harmless and suitable for long-term use.

Stainless steel thermos cup is better.
The corrosion resistance of stainless steel is stronger, if you often use a cup to make drinks (milk, coffee, etc.), it is recommended to choose 316 stainless steel. As for tea, the corrosion of stainless steel is relatively small. So whether it is tea, or flower tea, fruit tea
Stainless steel is more expensive than ceramic liner, but the hardness is stronger than the corrosion resistance of stainless steel, but it is not recommended as the first choice.
Ceramic cups and stainless steel have advantages and disadvantages, ceramic cups do not have those metal or other bad taste, but easy to break; Stainless steel is strong but sometimes grime and smell unpleasant.

These two kinds of thermos cups can not be compared, each has its own advantages and disadvantages, stainless steel thermos cups are convenient to carry, good thermal insulation performance, but must buy the real food grade 304 plate, many cheap stainless steel thermos cups on the market are 201 plate, which is not good for the body.
Ceramic thermos cup beautiful, good shape, insulation performance is relatively weak, shoelaces are not very convenient
The insulation effect is good stainless steel. Long holding time. From the health said ceramic thermos cup is good.
