Hamari gali main aate the ek baba ji sykil lekar awaaj lagate bhande kalai karalo.....or ham tab tak wahin sadak par baithe dekhte rahte ..jab tak poori gali walon ke bartan kalai na ho jate.......bachpan ki yaden taza ho gayin
Kalai can be done in various ways. Virgin grade Tin (called ‘Ranga’ in Hindi), caustic soda, sal ammoniac or ammonium chloride (called ‘Nausadar’ powder in Hindi), and water are used in the process.[21]
Kalai is required to be done on the vessels after approximately every two months of the doing the same.[21] Earlier, copper and brass vessels were used because of their high conductivity.[21] High conductivity of copper vessels reduces the fuel cost. Tin also conducts heat almost as quickly as copper, so there’s no question of copper losing its conductivity because of the Kalai. The vessels had to be tin-coated frequently to maintain the taste of the food as after sometime the food tastes bitter and it led to even food poisoning.[21] The copper, in traces gets dissolved in water when the water is stored in a copper vessel for a long period of time. This scientific process is called “Oligodynamic effect”.[21] Copper reacts with certain foods and can lead to gastrointestinal symptoms.[22][23] By doing Kalai, the deposition of tin layer works as a safe substance between the copper and the food.[23] Tin will melt if the temperature is above 425 degrees Fahrenheit (218.333 degrees Celsius).[23] Tin from the copper vessel wears away with time so usage of metal utensils, so wooden or silicon spatulas should be used. Cooking of acidic foods should be avoided. A chemical reaction between copper and oxygen called Oxidization turn the copper vessels black.[23] If Kalai is not done on the copper vessels, copper will react with the air’s moisture and create copper carbonate, which is green in color. This can make a person severely ill.[23]
Pital ke bartan Mein Kalai isliye ki Jaati Hai Taki khana jaldi kharab Na Ho Pital ke bartan mein Agar khana banaa kar thodi der Chhod Diya Jaaye aur khane Mein Yadi katai ka istemal hua hai to thodi der khana chhodane per jahreela ho jayega isliye Pital ke bartan Mein khana banane ke turant baad bhojan ko nikal Diya jata hai
@@Oldschoolbadass You cannot cook food items like tamarind/lemon directly on brass/copper vessels. Once coated with tin, it acts as a barrier and you can cook any food in it. Also tin is good for body. However you can cook rice/sweet/milk items on brass vessels safely without the tin coating.
