The porous glass thick film was fabricated by the diffusion‐induced phase separation and the sintering technique from scrap glass, polyvinylidene fluoride, and dimethylacetamide ( DMA c). Pores formed due to the dissolution of DMA c in water. As heat treatment temperature increases, densification of porous glass was gradually enhanced while the pore channels were maintained. Porosity data of ~62% and 55% were obtained at 700°C and 800°C, respectively. The pore size diameters were 91.1 μm (700°C) and 90.8 μm (800°C) separately. The porous materials showed acid durability partially because flower‐like crystals were dissolved in 1 M HCl solution. The process reported in this paper provided a simple method to prepare porous glass under one‐step calcinations at low temperature and was helpful for the reuse technology of scrap glass.
