The whole process of the occurrence of the skin egg is more fantastic: a raw duck eggs, with grass ash wrapped up thirty or forty days, and then open the dark green, transparent, can be taken at the same time the skin egg, and the taste is not yet finished. Through technical improvement, nowadays do skin egg is usually with lime powder, second tea, edible salt, flour alkali, grass ash, loess layer, grain shells and so on mixing and for the material mud, will be fresh and no cracks of the duck eggs one by one package mud, sealed tightly with a plastic film for 30-40 days that is the skin egg.
