What Material Is Enamel Pot

Enamel, formerly known as enamel, originated from glass decorative metals. It has the inherent mechanical strength and processing properties of metals, as well as the corrosion resistance, wear resistance, heat resistance, non toxicity, and decorative properties of coatings. Is enamel pot harmful to human health? Generally, high-quality enamel pots are non-toxic and harmless. It should be noted that enamel pots are not suitable for frying vegetables, and they should not store foods with strong acidity or alkalinity, otherwise harmful substances will be released into the food.

1, What material is enamel pot

Enamel pot refers to a pot made by coating enamel on the surface of a metal body, while enamel is a composite material made of inorganic glassy materials that are melted and solidified on the base metal and firmly bonded with the metal. Enamel mainly consists of two parts, namely metal material and enamel.

The metal materials used for enamel generally include steel, aluminum, copper, and stainless steel. Steel is mainly made of low-carbon steel plates, which are the main material for the inner liner of volumetric water heaters. And iron is mainly used as iron carbon alloys with a carbon content of over 2.11%, which are materials for producing cookware. Aluminum materials mainly consist of pure aluminum and aluminum magnesium alloys, while copper materials mainly include purple copper and brass.

The glaze raw materials used for enamel mainly include three categories: mineral raw materials, chemical raw materials, and pigment raw materials. The production of porcelain glaze involves melting these three raw materials in a certain proportion at a high temperature of around 1200 ℃, and rapidly cooling them to form granular or sheet-like borosilicate glass. It is divided into base glaze, surface glaze, edge glaze, and decorative glaze based on its technological performance; According to the different matrix materials, it can be divided into steel plate glaze, cast iron glaze, copper enamel glaze, aluminum enamel glaze, and stainless steel enamel glaze.

Enamel pots have good mechanical strength and physicochemical characteristics of enamel, which are good in corrosion resistance, wear resistance, heat resistance, and also have the characteristics of being non-toxic and decorative. Due to its beauty and lightweight, it has been favored by consumers.

2, Is enamel pot harmful to human health

1. Enamel pots are generally white in color, and the glaze solvents used for white enamel are silicon oxide, alumina, manganese oxide, potassium oxide, and sodium oxide. They are lead-free, so there is no risk of aluminum poisoning. Meanwhile, due to the stable chemical properties of enamel pots, they can store mild acidic and alkaline foods. So high-quality pot enamel is non-toxic and harmless. Generally suitable for making soup.

2. It should be noted that enamel pots should not be used for stir frying, as the enamel tableware coated on the outer layer of enamel products is actually a layer of enamel, containing substances such as aluminum silicate. When stir frying, collision and friction can easily cause damage, causing substances such as aluminum silicate to transfer to the food.

3. In order to extend the service life of the wok, it is best not to quickly cool or heat it up, and try not to store acidic foods such as vinegar and kimchi for a long time, as well as strong acidic and alkaline foods. When purchasing enamel pots, it is best not to use bright colors, such as red or orange, which may contain metals such as cadmium and are not good for the human body.
