The story of the successes and failures experienced by Real F\u00e1brica de Ferro de Ipanema, a 19th-century iron and steel enterprise in Brazil, has already been told and analyzed several times. Today we are very familiar with the technical difficulties faced by Swedes and Germans who were brought here to successfully produce large volumes of good quality iron in the inland regions of S\u00e3o Paulo State, a goal never achieved. That was a time when iron and steel production had already reached an advanced stage in Europe, where blast furnaces were built using scientific knowledge accumulated in previous centuries. But little is known about attempts to produce iron before the days of the Real F\u00e1brica. Then, ore was converted to iron using smelting methods carried out in the middle of the forest, using very small furnaces. Once produced, there were difficulties in distributing the output.<\/p>\n

Many practices employed in metal-working and smelting, and miners who specialized in gold, silver, and precious stones were brought to Brazil in 1598 by Dom Francisco de Sousa, seventh governor-general of Brazil, who served from 1591-1602. Sousa kept abreast of information about the occurrence of valuable ores in a region near what was then Vila de S\u00e3o Paulo de Piratininga, on Ara\u00e7oiaba Hill, 15 km from the present city of Iper\u00f3. Exploration at the site had begun a year earlier by Portuguese bandeirante and merchant Afonso Sardinha who, according to historian Pedro Taques (1714-1777), had hoped to find precious metals there.<\/p>\n

In Ara\u00e7oiaba, however, the abundance of iron ore was limited to magnetite. In order to take advantage of the potential of that area, furnaces and forges were built to make bars and simple pieces such as knives, spades, tools, and nails. \u201cThe smelters used practical knowledge in their work. They had no scientific understanding of the factors involved in the smelting process, especially with regard to what happens when the materials burn,\u201d said historian Anicleide Zequini, an expert in the field at the Museu Republicano in Itu, affiliated with the Museu Paulista at the University of S\u00e3o Paulo (USP). \u201cThose elements were not revealed until the so-called scientific revolution that occurred between 1789 and 1848, with the advances made in chemistry, and proceeded step by step with the Industrial Revolution.\u201d<\/p>\n

The efforts at Ara\u00e7oiaba Hill by Dom Francisco and Sardinha were short-lived. At the time, all or part of the investment funds had to be furnished by the entrepreneur. If capital was limited and the returns not immediate, the investor went bankrupt, as happened with Dom Francisco. His attempts were futile and he died in extreme poverty. Two similar initiatives followed. In the 17th century, in 1684, the Portuguese Luiz Lopes de Carvalho built an iron mill at that same site. To raise money he mortgaged his properties in Portugal, but soon went bankrupt. During the following century, in 1763, it was Domingos Pereira Ferreira\u2019s turn to try. \u201cHe must have been the last to produce iron on that hill, with the help of the smelters,\u201d Zequini says. It was not until 1810 that the Real F\u00e1brica was built, a few kilometers from that site.<\/p>\n

Ara\u00e7oiaba was not the only place in S\u00e3o Paulo where iron was manufactured in the 17th century. The F\u00e1brica de Ferro de Santo Amaro opened at Vila de S\u00e3o Paulo in 1607, the result of a partnership among Diogo Quadros, Francisco Lopes Pinto, and Antonio de Souza. It lasted a few years before shutting down.<\/p>\n

The activities carried out from the 16th to 18th centuries in inland S\u00e3o Paulo were researched between 1983 and 1989 by archeologist Margarida Davina Andreatta, one of Brazil\u2019s pioneers in architectural history, according to Zequini. The site researched and dug up by Andreatta was located with the help of Jos\u00e9 Monteiro Salazar, a history researcher in the region. She identified the site, known as Afonso Sardinha, and found rubble, tiles, various kinds of ceramics, vestiges of the furnace, and other structures. When Zequini wrote her doctoral dissertation about the site, she had the pieces she found dated and so proved that they were from the period she had studied. \u201cThat was the first 16th century site to be dated in S\u00e3o Paulo,\u2019\u201d says Andreatta. Now retired from USP, she still goes to the Museu Paulista twice a week and coordinates an archeological history group at the Bras Cubas University, in Mogi das Cruzes (SP).<\/p>\n","protected":false},"excerpt":{"rendered":"Attempts to produce iron in Brazil began in the 16th century","protected":false},"author":15,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[152],"tags":[241],"coauthors":[104],"class_list":["post-139499","post","type-post","status-publish","format-standard","hentry","category-retrospect","tag-history"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/139499","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/15"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=139499"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/139499\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=139499"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=139499"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=139499"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=139499"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
