Sliver leaf decorations
In Indian Sweets
Silver leaf decorations are added to the sweets to look more appealing and good to eat. Silver leaf decorations are made by pounding into a sheet less than a millimeter thick. It is backed up with paper for support and the paper is peeled before its been used.

Silver is expensive and the signs of luxury and wealth.
It makes the sweets look good beacuse of its lusturous self and its flexability.
Its put on sweets becuase there kept in fresh air for a long time and silver does not lose its lustre in pure air.
What is the chemical problem?
The chemical in this statement is silver. Well, silver is a very inactive metal. Silver sometimes slowy reacts with sulfur if it interacts with sulfur compounds in the air. Which forms a new sunbstance called silver sulfide which may cause health issues if its eaten. Since silver leaf does not contain much of silver so its not that harmful to the body. If there is much of silver consumed or exposure might also cause argyria. Mostly silver conducts heat which may cause environmental issues.

I strongly disagree that silver leaf decorations should be in indian sweets. There are more negatives to that side than positives. It can cause health issues, environmental issues, damages to the body such as death. Even though it looks appealing on indian sweets, luxury, expensive, and its has a wide industrial use. I believe that the diseases are a bigger part of a person surviving life rather eating.

Lustre: shows the beautiness of the decorations on the sweets to make them look delightful.
Reaction with the air: The silver leaf are made out of metal and does not lose lustre in pure air. The leaves have silver also included which doesn't react with water or air. Even though its silver it can get rusty which isn't a good thing.
