The defects of glass bottles can be divided into two categories: appearance defects and internal defects. The so-called appearance defects generally reflect defects that can be observed with the naked eye, while internal defects that are generally invisible to the naked eye can only be known with the help of measuring instruments and chemical analysis methods.
Defects on glassware products can also be divided into two categories based on their causes: melt defects and manufacturing defects. Melt defects refer to defects in the glass liquid itself, such as bubbles, stones, stripes, crystallization, color difference, etc. The main reason for these defects is due to poor glass melting. Defects formed during the manufacturing process of products, such as explosion cracks, microcracks, scratches, deformations, dimensional deviations, cold spots, wrinkles, streamline ripples, sticking molds, imprints, fire spots, pollution, and various decorative defects. These are all visible defects, while intrinsic defects mainly refer to the uniformity, annealing stress, chemical stability, and heat resistance of the glass. Appearance defects mainly affect the aesthetic effect of the product, while intrinsic defects directly affect the quality of the product.
