Chemistry Laboratory
Template:Languages Template:7ok
Source
This building becomes available after you have learned the Basic Chemistry tech.
Note: If a lab will be used for making explosives it should be built in a separate compound far from other buildings. The Explosives page has further details.

Level 2
This upgrade is only visible if you have an Essential Macerator in your inventory
"Upgrade this bench to allow essence creation"
- 1 Essential Macerator
- Requires:
- 1 Marble Mortar
- 4 Linen
- 1 Reagent Bottle
- 1 Thermometer
- 1 Thoth's Metal Sheeting
- 2 Bolt
- 2 Washer
- 10 Glass Pipe
- 4 Tin Sheeting

Alcohol Lamp
The Alcohol Lamp must first be assembled using the Skills->Assembly menu. It requires:
- 1 Reagent Bottle
- 1 Small Gear
- 1 Gold Wire
- 1 Rope
Glassware
Install one each of the following:
Chemistry Labs require a level 1 upgrade to be able to install glassware.
Labs used to make Explosives do not need high quality glassware. A quality of 1 is sufficient.
Glassware of specific quality will allow for the lab to be calibrated. Calibrated labs give increased powdered gem yield, increased litmus strip solution, and require fewer essences per essential compound.
Calibration level 2 requires the glassware to have an average quality exactly divisible by 100 (rounded down), and an average quality above 7000. It reduces the cost of an essential compound from 70 debens to 40 debens.
For calibration level 3 the average quality of the glassware must be exactly 8000 or 9000, rounded down. (The sum of the glassware quality must be between 40000 and 40004, or 45000 and 45004). It reduces the cost of an essential compound from 70 debens to 35 debens
It is STRONGLY recommended that if you are going to calibrate a lab, you calibrate it to level 3. The amount of time and resources saved for a level 3 lab vs a level 2 or level 1 lab is well worth the potential extra outlay costs.
Additional Information
You will not get any upgrade stuff back when you salvage an upgraded Chem Lab at salvage level 7.

When pulverizing bones into Bonemeal, the quantity depends on the type of animal bone used. Rabbit Bones give ?, Sheep Bones give 3, Beef Bones give 4, and Camel Bones give 5.
Powdered Gems
Used for Test of the Ritual Tattoo and certain Essences.
You must have the gems in your inventory in order to see the option on the lab.
Powdered gem yield is multiplied by (1 + the precise calibration level of the lab). At calibration 3 (maximum known), yields are multiplied by 4.
| Gem Size | Quantity Made |
|---|---|
| Huge | 7 |
| Large | 4 |
| Medium | 2 |
| Small | 1 |
| Cuttable | 1 |
| Cut Gem (Any Cut) | 1 |
The wooden pestle breaks after some number of powderings and has to be replaced.
Note: A Gem Cutting Table installed with a Gem Shearing Chisel can turn any gem into an average of 3.5 (1-7) gems of the next smaller size. Breaking down bigger gems into small will yield more powder than powdering them directly. Be aware that fracturing and pulverizing only a single gem increases the probability of a lower (or higher) than average yield
For example, using 1 huge gem in a lab with calibration 3:
Unfractured
- 1 Huge * 7 * 4 = 28 gem powder
After fracturing and pulverizing (average yield):
- 1 huge * 3.5 = 3.5 large gems
- 3.5 * 3.5 = 12.25 med gems
- 12.25 * 3.5 = 42.87 small gems
- 42.87 * 4 = 171.5 gem powder
