经不同强化处理（即钢化、热强化、化学强化）和未经处理（退火钠石灰玻璃）的商用玻璃锡面进行了成分和表面表征，然后与大猩猩玻璃®进行了比较。用原子力显微镜观察了热处理试样表面强度处理后的缺陷。拉曼研究表明，由于处理引起的结构不同，网络连通性（Q2/ q1比率）有所差异。用XPS对锡的氧化态进行了评价，比较了不同处理下锡的氧化态变化。补充，关于裂纹行为的研究使用维氏压头进行；与Gorilla glass®相比，浮法钠钙玻璃的开裂模式有所不同。此外，由拉曼光谱测定的IQ2: iq1比值与压痕产生的裂纹尺寸相关。
Tin side of commercial glasses with different strengthening treatments (i.e. tempered, heat strengthened, chemically strengthened) and without treatment (annealed soda-lime glass) have been compositional and surface characterized and then, compared with Gorilla Glass®. Surface flaws from the strength treatment were observed in thermally treated samples by AFM. Raman studies show differences in the network connectivity (Q2/Q1ratio) because the different structures caused by the treatments. XPS was used to evaluate the oxidation state of the tin and compare the variations through the different treatments. Complementary, a study about the crack behaviour using a Vickers indenter was performed; different cracking pattern was obtained for float soda-lime glass in comparison with Gorilla Glass®. In addition, the IQ2:IQ1ratio as determined from Raman spectroscopy correlates with crack size from indentations.
