Looking at the gaudy half-finished silver-plated glass mirror before them, the two of them were caught between laughter and tears. Still, they were not discouraged. They had already worked out the correct method for capturing images, and now they were only a tiny step away from preserving them completely. They had also unexpectedly discovered how to silver glass, so they were quite happy deep down.
Next, the two of them simply opened all the windows and doors and focused on making a glass mirror. Ao Fei brought over a new piece of smooth glass, while Qu Bing began preparing the silver-plating solution. However, during the preliminary cleaning, no matter how Qu Bing wiped it, some dust and tiny fibers always remained on the glass. Even if the silvering succeeded, those would leave flaws on its surface.
Ao Fei had been studying lenses for some time and had long since developed a special way to clean them. First, he held a mouthful of clean water in his mouth and sprayed it into the surrounding air, reducing the dust floating in the air. Then he had Qu Bing scrub the glass with alcohol. After going over it like that, they really did obtain a clean glass surface.
Once the alcohol had naturally evaporated, Qu Bing poured the two mixed solutions directly onto the glass, then tilted the glass so the solution spread evenly across it. Before long, a thin silver-plated coating precipitated onto the glass. After rinsing away the excess solution with clean water, the two of them had a complete silver-plated glass mirror.
"This mirror gives such a clear reflection! I wonder how much better it is than a bronze mirror. If we sold it, plenty of people would fight to buy one," Qu Bing exclaimed.
"A mirror with such powerful
