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.

Cost

• 214 Nails
• 19 Rope
• 10 Wooden Peg
• 5 Copper Sheeting
• 1 Wooden Pestle
• 1 Clay Mortars

Built in a Compound. Uses 13x15 cells.

(Lets you make Arsenic, Gunpowder and Ink

Upgrades

Tech required: Advanced Chemistry 2

Level 1

"Upgrade this bench to allow advanced reactions"

• 1 Brass Plate
• 20 Glass Jars
• 1 Thermometer
• 4 Bolt
• 8 Washer
• 4 Magnesium Wire
• 20 Steel Wire
• 1 Stainless Steel Pot

(Lets you make Papyrus Strips)
(Add Glassware (which lets you calibrate it) to make Gear Oil, Potash Ointment, Lime Emulsion, Acid Extract, Gem Glue and Explosives)

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
• 4 Bolt
• 8 Washer
• 20 Steel Wire
• 20 Gold Wire

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:

• Thistle Tube
• Test Tube
• Distillation Coil
• Beaker
• Florence Flask

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.

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
