Which material is used for household glassware such as jars and window panes and is known for transparency and heat resistance?

• A. Glass
• B. Ceramics
• C. Composite
• D. GRP

Answer: (A)

Choosing a material for household glassware and windows comes down to being see-through and able to handle heat. Glass is transparent, so jars and window panes stay clear, letting you see contents or through the pane. It can be formed into thin, smooth shapes that are easy to clean and sterilize, which is ideal for jars. It also resists heat reasonably well, and with variants like tempered or borosilicate glass, its resistance to thermal shocks is improved, making it safe for hot liquids and everyday temperature changes in windows and cookware. Ceramics are generally opaque, composites and GRP are typically not transparent, so they don’t meet the requirement for see-through visibility. That combination makes glass the best fit for these uses.
