Abstract:	Oral tradition tells us that egg whites were used as ingredients of mortars, which are used to bind building materials for the construction of churches, and other architectural structures, during the Spanish colonial period in the Philippines. Egg whites comprise mainly of proteins, specifically ovalbumin. To see if our church builders used egg whites as mortar ingredients, can we simply qualitatively test them for the presence of proteins? Or do we need sophisticated techniques?
