Red lead or minium (Pb₃O₄)
Minium, also known as red lead, is a ceramic pigment used to produce red tones in ceramic glazes. This pigment is highly valued for its ability to provide a rich range of red colors, from intense, warm tones to darker hues.
However, minium is a highly toxic compound and its detrimental effects on human health and the environment have led to a significant decrease in its use in recent decades. Read lead, being a heavy metal, presents intoxication risks, especially when it comes into contact with food or beverages, which makes it dangerous in ceramic pieces that are in direct contact with these products. As a result, it has been replaced by safer alternatives, such as pigments based on iron oxides or lead-free ceramic compounds.Interesting Fact
The use of minium is not limited to ceramics, as it has also been used in painting, glass manufacturing and other industrial applications due to its chemical stability and its ability to provide long-lasting and striking colors.Helpful Tip
If you decide to work with minium, strictly follow all safety precautions, including the use of personal protective equipment and proper waste disposal. Always look for less hazardous alternatives whenever possible, especially for parts that will come into contact with food.
