The alchemy lab is the tenth building in the game, initially costing 75 billion cookies. Each alchemy lab initially produces 1.6 million CpS by turning gold into cookies. When fully upgraded, they each produce 409.6 million CpS.

Alchemy labs are twice as efficient. "Pushing alchemy to its most extreme limits, you find that everything is transmutable into anything else - lead to gold, mercury to water; more importantly, you realize that anything can -and should- be converted to cookies."

The Alchemy lab is the fifth most expensive item you can purchase. It will give you 500 cookies every 5 seconds by transforming gold.
It initially costs 50,000 cookies, increasing in price by 10% with each consecutive purchase. Some grandmas will change to that of a golden grandma.
Buying your first Alchemy Lab will increase Grandma output by +4 cookies per 5 seconds.
The Alchemy Lab of Cookie Clicker parodies one of the most well-known goals of Alchemy, to devise a way to transform lesser metals, such as lead, into higher metals, usually gold.
The economic consequences of transforming the rare element of gold into cookie material have not been fully explored by the game, but it would likely cause inflation in many of the world's currencies. However, given that the player is likely to create cookies at a fast enough rate to end world hunger entirely, a post-scarcity economy may have emerged in its place, potentially limiting the need of currency, to begin with.
A news tick suggests that gold is not the only precious metal that can be used in Alchemy Labs. Silver can also be transmuted into white chocolate, according to the titles, but there are no other upgrades or achievements that support this. Additionally, the process of converting gold into cookies appears to be reversible.
The "Aqua crustulae" upgrade name means "Water of cookie" in Latin. It's probably is a reference to Latin expression "Aqua vitae" that means "Water of life".
The "All that glitters is gold" achievement is a reference to the chorus of "All-Star" by Smash Mouth.
The "We could all use a little change" achievement is a reference to "All-Star" by Smash Mouth.
