===2.  Work with and isolate alchemical materials.===

Only full-fledged alchemists can isolate alchemical compounds, and only then with the aid of an alchemical lab.  Doing so requires a period of one week, the consumption of 100 gp worth of reagents and catalysts and a throw of 14+ in order to be successful.  The amount of material that can be refined within this time period depends on the material in question.  The alchemist's lab must be worth a minimum of 1000 gold in order to attempt this (it is not possible to do so in a traveling lab).

The alchemist can improve her chance of success in the following manners.:
*For every additional 2000 gp in value of the lab she gains a +1 bonus to the throw.
*Possessing a library worth 2000 gp adds a +1 bonus to the throw.  A successful throw indicates the value of the library is increased by 500 gp, due to the notes she has taken during the process.  
*For every additional 1000 gp of worth of the library add +1 to the throw.
*For every additional week spent add +1 to the throw.
*For every additional 500 gp worth in materials and consumable materials add +1 to the throw.
*Note that uncommon or rare items will likely have a higher throw.

A throw of 1 will always fail and has a 50% chance of destroying the substance in question.
