La mínima emisión de co2 y evaporación del agua hacen que la arena sea un desengrasante apto

Abstract

This experiment set out with the purpose of determining the best temper agent between sand, quartz and sawdust. To achieve this, three ceramic bowls were made with 300 g of clay and 10 g of temper. After this, the absorption capacity of each bowl was checked using 80 ml of oil in each container for 30 minutes, after which the remaining amount of oil was measured. This process was repeated a second time. The results indicate that the sand is the best temper agent, while sawdust is the second, leaving the quartz in the last place.
