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
Answer
Brief Explanations:
Stained - glass is made by adding metallic oxides to sand and ash or lime, and then fusing at high temperatures. Metallic oxides give the glass its color, and sand, ash or lime are the main components of the glass - making mixture. High - temperature fusing is necessary to melt the components together to form glass.
Answer:
A. adding metallic oxides to sand and ash or lime, then infusing at high temperatures
