Taking kitchen litho further into the kitchen...
I'm using Émilion's discovery of coke as an etching solution on top of aluminum foil in what she calls "kitchen lithography" and adding more kitchen ingredients--tapioca flour and pancake syrup--to the process. Cola works as an etching solution because it contains phosphoric acid, and pancake syrup (the cheap stuff) works as a binding agent because it contains gum.

Estou usando a invenção da Émilion na França de usar coca cola para gravar folha de aluminio (litografia caseira). Adicionei mais dois ingredientes de cosinha--polvilho e melado de panqueca--ao processo. A coca serve para fazer gravura porque contem acido fosforico, e o melado de panqueca serve como protetor porque contem goma.
