Cover Photograph: Episcopic microscope images taken from the glass side for the stack composed of glass enamel screen printed and fired at 650°C for 180 s onto glass substrates with different composition: A, Soda‐Lime Silica glass, B, Borosilicate AF45, C, Borosilicate Eagle 2000.The enamel deposited on the borosilicate AF 45 and Eagle 2000 demonstrates that the enamel layers present a network of cracks, initiated in the layer and propagating further to the glass substrate.The amount of cracks at the interface between the film and the glass substrate increases with the amount of tensile stress present in the enamel. https://doi.org/10.1111/ijag.15478

封面照片：从玻璃侧面拍摄的镜面显微镜图像，由玻璃搪瓷丝网组成的叠层印刷并在650°C的温度下焙烧180 s在具有不同成分的玻璃基板上：A，苏打石灰玻璃，B，硼硅酸盐AF45，C （Borosilica Eagle 2000）。沉积在硼硅酸盐AF 45和Eagle 2000上的搪瓷表明，搪瓷层存在裂纹网络，裂纹始于该层并进一步传播至玻璃基底。玻璃基底随搪瓷中存在的拉应力的增加而增加。https://doi.org/10.1111/ijag.15478
