The goal in winning is to have eggs with hard shells! (Well, also a hitting technique exist).
So this is why I started the topic, I'd like to "cheat a little", by finding a way of hardening my egg shells. Remember, it has to look normal, no epoxy paint is acceptable for example.
I thought about something. Maybe dipping it in a hot solution of calcium chloride for some time, to let it be absorbed in the pores of the casing, and then dipping it in sodium silicate. Calcium silicate will form in the pores, which would harden the shell, right? Or a carbonate, resulting in the formation of CaCO3
Reaction 1: CaCl2 + Na2SiO3 ---> CaSiO3 + 2NaCl
Reaction 2 : CaCl2 + Na2CO3 --> CaCO3 + 2NaCl
