how is stained glass made?\na. adding metallic oxides to sand and ash or lime, then infusing at high temperatures\nb. adding metallic oxides to salt, then infusing over time at low temperatures\nc. adding metallic oxides to sulfur, then infusing at high temperatures\nd. adding metallic oxides to sulfur, then infusing at low temperatures\nplease select the best answer from the choices provided\no a\no b\no c\no d
Answer
Brief Explanations:
Stained glass is made by adding metallic oxides to sand and ash or lime (the main components of glass - making materials), and then infusing at high temperatures. Salt and sulfur are not the base materials for glass production. Low - temperature infusion is not the typical process for making stained glass.
Answer:
A. adding metallic oxides to sand and ash or lime, then infusing at high temperatures
