Abstract

Experiments in which recently excavated artifacts were soaked for at least four hours in 40 g/liter aqueous solutions of CalgonTM (sodium [hexa]metaphosphate), then rinsed off in a colander under tap water, show this method to be 1.5 to 6.4 times more thorough than traditional scrubbing while taking only two-thirds the time. This method, particularly effective in cleaning large batches of small or intricately surfaced objects, is a practical cost-saving procedure in both public and private-sector research.

Résumé

Résumé

Experimentos en que artifactos recién excavados fueron remojados por al menos cuatro horas en soluciones acuosas de 40 g/litro de CalgonMR (hexametafosfato de sodio), y después enjuagados con agua potable en un colador, demostraron que este método es entre 1.5 y 6.4 veces más completo y más rápido (2/3 del tiempo) que el método tradicional de fregarlos. Este método es particularmente efectivo en limpiar lotes grandes de objectos pequeños o de superficies intricadas y es práctico y económico en investigaciones públicas y particulares.
