In Archaeology, screening or sifting is the action of separating materials from soil samples obtained by excavating at excavation sites. The screening station at the Varrock dig site is the only area where this can be done, unless the Auto-screener v1.080 has been made, using blueprints that can be purchased from Ezreal who runs the Archaeology Guild shop (this requires the Associate rank within the guild and 50,000 Chronotes).
Experience from screening is initially 1 exp per soil, and is increased at Archaeology levels 38, 71, 93 and 111, to 3 , 5, 12 and 20 exp respectively. Screening takes 3 ticks per item equivalent to 3 minutes per 100.
A higher Archaeology level increases the chance of receiving materials from soil.
Screening soil also has a rare chance to produce an artefact from the same area as the soil sample.
There are six different types of soil. The minimum level is the level required to be able to access the dig site with that soil. The maximum level is the highest level of the material which can be obtained with that soil.
|Dig site||Soil type||Minimum level||Maximum level|
|Varrock Dig Site||Senntisten soil||1||1|
|Infernal Source||Fiery brimstone||20||36|
|Stormguard Citadel||Aerated sediment||70||98|
