An ambitious collector who decides to travel to time and collect famous things from various times and make a historical collection, but it will not be easy as he thought!
A man sporting a curled mustache stepped forward and explained the problem while scratching the side of his head. "See, we recently changed one of our suppliers. We have two materials we used to melt together to make a type of ceramic. The ceramic is used for potion bottles and is very resistant to acid." He held up a sliver of glass that looked faintly green in color. I recognized it as the same glass I used to keep my poisons and potions in. "However, the newly supplied material isn't bonding the same way. It's brittle, acid breaks it down, and if you add magicly enhanced potion, it seems to leech the magic out and becomes heavier than sin."
