1) The designs I stamp onto my prosphora and lytia loaves tend to disappear by the time the baking is done. Why? How can I stop this? There is a prayer for prosphora bakers to pray prior to baking:
O Lord Jesus Christ, only begotten Son of the Eternal Father, who has said with Thy most pure lips: Without me you can do nothing. O Lord, my Lord, with faith I accept your words; help me a sinner, to prepare the Bread of Offering, that the works of my hands may be acceptable at Thy Holy Table and may become through the operation of Thy Holy Spirit the communion of Thy Most Pure Body for me and for all Thy people. In the Name of the Father, and of the Son, and of the Holy Spirirt. Amen.
For the litiya breads, I figure you are using 2 biscuit or cookie cutters to cut 2 different sized discs after rolling out the dough to a thickness of less than about a quarter inch.
. Preheat your oven, and don't let a lot of time lapse from the time you stamp the dough until the time you put your breads in the oven.
. Use the seal on the smaller of the two discs, making sure to get a clearly etched seal before putting the two pieces together.
. Moisten the larger disc top, place the smaller one on top of it, then use a wooden skewer or toothpick to poke holes around the seal, down through the dough to the bottom of the lower disc.
The water seals the 2 discs together, along with the toothpick holes. The toothpick holes also puncture air pockets which can cause the dough to rise too much.
The dough's consistency, the oven temperature, etc. can all cause success or failure. My wife has a knack for baking, and says I treat the dough like a punching bag when I try to knead it myself. I guess you could say she is "at one with the dough", because she knows what needs to be done in order to bake breads, cakes, cookies, etc. The only baked item she avoids is pie crust.
Purists will say you must knead the dough by hand, but a Kitchen Aid mixer does a superior job of kneading the dough. So, if you work around purists, just be discrete and don't tell them.

The breads finished in the correct form are what really matters. My wife says she will be glad to talk by phone with you if you want a more direct discussion.
