Question

which type of glass contains added compounds to increase the strength of the glass and to insure stability in high temperatures?

laminated glass

crystal glass

density glass

borosilicate glass

Explanation:

Laminated glass is for safety (multiple layers), crystal glass is decorative/optical, "density glass" is not a standard type. Borosilicate glass has added compounds (like boron oxide) to increase strength and thermal stability, used in high - temp applications (e.g., labware, ovenware).

Answer:

D. Borosilicate glass
