Antique British Porcelain Chemical jars made by Pearson Pottery, Nottingham, England for transporting chemicals to colonial countries that’s the reason for the twin tone colour denoting toxic contents but later the empty jars were sold for low price to Indians who used them for storing Salt, pickle, tamarind and other food stuffs because of the fact that they lasted long and they become so popular that even till date newly made porcelain jars also follow the same colour pattern without knowing what it really stands for.
