What is Asbestos?

According to Who.int, Asbestos is a group of naturally occurring fibrous crystals that have poor heat conduction and relative chemical resistance. All types of asbestos, including white asbestos (Chrysotile), are harmful to health. Since 1973, The International Agency for Research on Cancer (IARC) of the World Health Organization has classified all types of asbestos as Group 1 carcinogens in humans, based on 40 years of research and evidence from human and experimental studies.

Why is asbestos dangerous to humans?

Asbestos crystals, when entering the body, can cause lung cancer, larynx and ovarian cancer, malignant mesothelioma (a type of lung and abdominal cancer), and asbestos lung dust (pulmonary fibrosis), as stated by WHO.

Are there really asbestos in Chinese thermos bottles?

Asbestos is used in double-layer glass thermos bottles to secure the two glass layers and provide insulation, reducing product costs. However, stainless steel thermos bottles do not contain asbestos as the insulation layer is welded. It can be difficult for consumers to distinguish between thermos bottles and tea infusers that use asbestos, so it is best to choose reputable suppliers, brands, and stores.

Recommendations from professionals

According to Assoc. Prof. Dr. Tran Hong Con from the Faculty of Chemistry, University of Natural Sciences, VNU-Hanoi, asbestos only poses a danger when it is released into the environment and becomes broken pieces. Therefore, it is crucial not to break or remove the thermos bottle to avoid releasing asbestos outside.
