Not from the lab, but this is also chemistry: crystalline glaze vase!

This special type glaze crystallizes at a specific temperature while the vase is burned. How does the work? The glaze contains a lot zinc oxide, and a few secret component what melts at 1200 °C. While the vase is in the furnace it is cooled slowly (under hours) from 1200 °C to 1150 °C what lets the glaze to crystallize, just in a beaker in the lab. If the glaze is cooled down too fast, small crystals or even no crystals form, or if its cooled down under days, really large, even cm long crystals could form on the surface of the vase.  

Why is this so interesting? Every glaze what is made via this method is unique and unrepeatable, since its impossible to grow the same amount and the same shape of crystals on its surface.

Artist recreates his childhood doodles 20 years later

In his series “Kiddie Arts,” Telmo Pieper took his old doodles and used Photoshop to digitally recreate them in a realistic style. While the pictures still look bizarre and fantastical, it’s fascinating to see the two versions — one by a child and one by an adult — side by side. [article]
