Dear friends,
I am searching for reduction of corrosion in copper utensils which we use in household purpose.
The classic solution for this is tinning. Even in ancient times, copper vessels were made food grade by tinning. That still applies today. If you absolutely need a dielectric, a polimeric coating could help, for example, a car paint. However, this type of coating is only suitable for decorative purposes (not for cooking and not for contact with food).
Dear vadim verlotski,
thanks for your kind information on my query on copper plate corrosion and improving it by tinning.
does the antimicrobial activity of tinning will reduce? also am having some other query that mostly cooking and storing of food in copper vessels are not recommonded for long time.
Copper itself has an antibacterial effect, which is why, for example, cent coins made of steel are copper-plated. Unfortunately, antibacterial effect of copper is based on toxicity of Cu ions. For this reason, copper containers are not recommended for contact with food. Tin, on the other hand, is non-toxic and is often used to make contact with food (metal conserves are made of either aluminum sheet or tinned sheet steel). Tinned copper sheet is harmless in the sense of toxicity.
Dear Vadim Verlotski,
thanks again sir, as it every one knows that copper has high antibacterial effect that's why people will recommended for storing the drinking water in copper utensils for longer duration too.. and also humans drink water by keeping in copper vessels.
i am having a doubt sir does if use copper tinned material with contact to the water which is non toxic and does have anti bacterial effect.
please clarify sir..
Tin has no antibacterial effect and is not toxic, so it is biologically neutral. Copper and silver have antibacterial properties but are toxic. It can be good to protect water from bacteria, but it is dangerous to store food because toxic copper or silver ions are dissolved in food.
