In the year of 1970, Aluízio Siqueira was interested in the art of stained glass and he started to study the subject. He had countless difficulties, because there was no literature in Portuguese, neither was there suitable material in the Brazilian market, besides clear glass, Brazil has little colored or stained glass. For such, Aluízio created and set up a machine to extrude the lead gutter, in form of a H. He imported the tools and necessary machinery, except for the ink.

Aluízio designed and executed the stained glass in
