Neste trabalho 68 contas de vidro encontradas no sítio arqueológico do Cais do Valongo na zona portuário do Rio de Janeiro foram analisadas usando a técnica de fluorescência de raios de raios X (XRF). Para análise por XRF as contas foram separadas seguindo as suas formas e coloração: nove de cor branca e cilíndricas, quinze de cor vermelha e cilíndricas e quarenta e quatro de cor azul e facetadas. Para a análise das contas foi utilizado um sistema comercial de XRF (ARTAX 200 - Bruker) composto por um tubo de raios X com anodo de Molibdênio e um detector XFlash. As condições operacionais de análise foram: 35 kV, 500 μA e tempo de exposição de 600 s. Foi possível detectar 16 elementos: Si, K, Ca, Ti, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Sr, S...
