Urns

Urns are a type of pot that can be made using the crafting skill. They were released on 15 February 2011 and were first mentioned in the February 2011 Behind the Scenes article. While training fishing, mining, smelting, cooking, or woodcutting, urns will "collect" scraps and eventually become full based on the experience gained from the activity. Once full, the urn can be teleported to Ernie for additional experience in the skill that was being trained to fill the urn. The amount of additional experience received from teleporting a full urn equates to exactly 20% of the experience used to fill the urn.

Only "base" experience counts towards filling the urn. For example, if you were to mine two ores at once using the Varrock Armour, only the experience from the first ore will be added to the urn, but not the second. Anytime "bonus" experience is given (such as Penace Horn or Sacred Clay item, or a special experience gain such as a minigame reward or Genie Lamp), it is not counted towards filling the urn. For example: Collecting a Magic Log with a Sacred Clay Hatchet will add the "base" 250 exp to the urn, but not the extra "bonus" 250 rewarded from the hatchet.

Prayer urns operate differently in that you do not receive any experience until the urn is teleported away. As soon as you teleport it away, you receive all of the experience you would have from spreading the demonic ashes normally along with the 20% experience bonus. You do not receive prayer ash drops, as they are automatically added to the urn and the experience is gained once it is teleported. This allows training prayer by killing Demons from a safe spot without having to leave the safe spot to collect ashes.

You will need to finish the urn that you have started filling before you can fill another of the same skill type. You may have multiple urns from various skills, however; for example, you could start filling a cracked fishing urn while you are still filling a cracked mining urn. You may only have 10 non-empty urns in one skill type at a time (these are urns with any number of scraps in them: a pot with one scrap in, all the way to a pot that is completely full). Unfired urns, urns without runes, and empty urns with runes do not count towards this total.

Urn creation
Note: A fired urn without a rune attached is tradeable; all other urns are untradeable.

First, the player must go to a Pottery wheel and use 2 pieces of soft clay on the potter's wheel. Players must then select a type of urn and craft it on the wheel to make an Urn (unf). The types of urns that players can craft depends on the player's crafting level. Urns that require a higher crafting level to create will catch scraps from higher level training activities. The Assist System can be used to craft urns that are above a players crafting level. Alternatively, the urn (unf) can be bought from other players.

Once a player has an Urn (unf), they can then use the urn on a pottery oven to make an Urn (nr). Players must then add a rune to the urn in order to make an Urn (r) wich can be used to gain bonus XP. Each urn uses the following rune:
 * Fishing - Water rune
 * Cooking - Fire rune
 * Mining - Earth rune
 * Smelting - Fire rune
 * Woodcutting - Earth rune
 * Prayer - Air rune

Players can then train any skill as they normally would with the urn in their inventory. When the urn is full, the player will receive a chatbox notification and the Urn (full) will have a teleport option. Players can then teleport the urn to receive experience.

Percentage formula
You can use the following formula to estimate the percentage increase in filling the urn per unit material:

20 x (unit exp / urn exp)

For example: A yew log gives 175 and a strong woodcutting urn gives 1662.5 exp. The formula estimates:

20 x (175/1662.5) = about 2.1% per log.

For the prayer urns the formula is a bit different, since the bonus exp including the unit exp is awarded when the urn is teleported. The formula is then:

120 x (unit exp / urn exp)

Trivia


When you "Check Level" of an urn that is exactly half full, the message shown is "This (urn type) is half full, or is it half empty?" as opposed to "This (urn type) is 50% full."
