Adding lime (CaO) to a glass will cause what change?
Decreased transparency
Decreased softening point
Increased transparency
Increased softening point
Adding lime (CaO) to glass will cause an increased softening point.
Explanation: Lime (CaO) is a stabilizer. Although an excess of calcium oxide to a silica melt will cause devitrification, additions of small amounts of lime stabilize the glass melt with respect to water, fixing the problem of water solubility introduced with the soda component. The softening point is the temperature at which a material softens beyond some arbitrary softness.

Figure 1A shows the locations of the five anole lizard
populations in the study. Figure 2A shows the mean
CTmin (critical thermal minimum, the temperature
at which lizards lose their coordination) over time for two of the
populations. Figure 2B compares the mean CTmin
values for all five populations in the summers of 2013 (closed
