Wax doesn't normally come off during etching. However, if the lines are too fine/thin, the acid can easily undermine (attack sideways below the wax from an etched area) the waxed lines and the wax will come off with a bit of shell.
If you are having this problem, you should consider either etching for a shorter period of time, or writing with a wider stylus. Medium or fine are OK; extra fine or narrower usually come off.

Why do you have to wash and dry the specimen after etching?
Washing and drying the specimen after etching removes any residual chemicals and contaminants from the surface, ensuring accurate results during further analysis. It also prevents any potential interactions between the etching solution and the subsequent processing steps. Additionally, drying the specimen helps prevent corrosion or oxidation of the newly exposed surface.

Does hand mouth foot get other your fingernails causing them to peel off?
Yes. Many people report problems with nails peeling during the virus's run, and more often after the symptoms seem to be gone... including up to as much as 6-8 weeks afterwards. So people often miss teh association between the virus and teh peeling. The virus and peeling can happen in children, and speaking from direct experience, in adults as well. No pain is associated with the peeling at all, but the peeling nails can get snagged on things, which of course can be painful.

What are the origins of pysanky?
Ancient people worshipped the sun, which warmed the earth and was the source of all life. In winter, earth was dormant and appeared to be without life. Likewise a whole egg appears to be lifeless. In spring the earth renewed herself, and new life sprang from the egg. Thus the egg is a perfect symbol of the sudden burst of life from dormancy. Ancient Ukrainians believed that eggs had special powers. Eggs were decorated with symbols that had magical and protective powers; these powers were thus transfered to the egg, which was used for talismanic purposes. When Christianity came to Ukraine (Kyivan Rus), the egg was incorporated into Easter celebrations. Easter is the culmination of the Christian year, and celebrates the victory of life over death. The pysanka, which had been created in ancient times during spring festivities celebrating the rebirth of nature, was an ideal symbol for then new Christian Easter holiday. Pysanky created for Easter had many purposes. The original purposes were protective and magical. Pysanky were left in a bowl in the house to protect it from evil. They were placed in the stables and beehives to not simply protect the beasts of the household, but to insure their future fertility. Pysanky were hung in fruit trees to assure a plentiful harvest, and farmers buried eggs in their fields to assure a bountiful harvest. Pysanky were also given as gifts to friends and family: children received light, colorful pysanky with floral designs, while teenagers received eggs with lots of white, indicating that their future was a blank page. Married couples received 40 triangle eggs, which represent power in all facets of life, while older people received black eggs with ladders and gates, representing the ascent to heaven. Making pysanky was not a social event, but an important religious ritual. The women of the family would gather on the given day, say a few prayers, and work together to produce a family's pysanky. Men rarely participated (it was unheard of), and this ritual was performed in near silence at the end of a day sanctified by refraining from gossip, argument, or sin. The pysanka maker prayed that the recipient of her eggs would be endowed with joy, good fortune, happiness, and protection from harm. In the mid-19th century traditions began to change as the world grew more modern. Pysanky were less and less considered magical objects, and more and more considered mere objects of art. They began to be sold, and used mainly as pretty decorations. The knowledge of the meaning of their symbols began to be forgotten. And rather than being made and given away during the great spring holiday (velykden), they began to be given away year round.
