Abstract: Through by used high temperature melting experiment, reaction temperature of fining agent such as SnO2, CeO2and Na2SO4in the role of high aluminosilicate system were researched, and then according to the results of the high temperature observation research,two groups of compound fining agent were selected to contrast the effect of compound fining agent on clarification was discussed, analyze the changes of bubble quantity and dimension in glass clarification process.Results show that reaction temperature of three kinds of fining agent which role in high aluminosilicate glass are slightly lower than role in normal sodium calcium silicon, gradient clarification formed by using SnO 2and Na2SO4as compound fining agent are more apparent effect than Synergy Clarification formed by using SnO 2and CeO2 combination,clarify effect is well.
