Extra fine sand detail.png

Extra fine sand is an item used in the creation of the Orthen furnace core and blessed sand. It is made at level 20 Crafting by grinding any size of sandstone. The likelihood of receiving extra fine sand scales per kilogram, meaning heavier sandstone blocks provide a faster rate of sand.

The next step of the process to create blessed sand is to bless the extra fine sand by using it on certain Saradominist altars (or using the 'bless' option while in range). A total of 40,000 extra fine sand is required to make a blessed flask, 1,000 is required to make an artificer's measure, and 100 is required to make an Orthen furnace core.

Conversion rate[edit | edit source]

Each size of sandstone has a different chance of granting sand, and the larger sizes can grant multiple sand at once.

Overall, from a sample of around 7000 of each sandstone, the average sand received per block of sandstone appears to be almost exactly 1 sand per 10kg of sandstone ground.

Buying sandstone[edit | edit source]

If one were to buy sandstone, the rate is very simple. It takes two ticks to grind each sandstone, and add on a few ticks to reload the inventory using a preset (in this example we will use 4 ticks). Thus an inventory will take 60 ticks.

With the addition of Telekinetic Grind, there is an alternative way to grind sandstone. Each cast of the spell consumes 1 law rune and 2 astral runes, and grinds the entire inventory in a single tick. With a law staff will reduce the effective law rune cost to 0.9 per cast, and using a large rune pouch to effectively equip the astral runes will allow 28 sandstone per inventory. The following assumes the use of a law staff and large rune pouch, and 4 ticks per inventory (though it can easily be done in 2 or 3 ticks with practice).

Size Avg. sand per inventory Manual grinding Telekinetic Grind
Expected sand per tick Time for 40,000 sand Expected sand per tick Time for 40,000 sand Additional cost

Thus, as expected, 10kg is the fastest and the other sizes follow.

Mining sandstone[edit | edit source]

Mining sandstone is a more interesting analysis, as you have several options. You can grind everything you mine, or you can choose to drop some of the lower sizes to change the balance of time between mining and grinding - so you don't spend time grinding the clearly worst options.

Each of the four sizes is exactly equal chance to mine - 1/4.

Here follows the calculation. There are four sensible options:

  • Grinding everything [all]
  • Dropping 1kg and grinding 2kg, 5kg, and 10kg [2kg+]
  • Dropping 1kg and 2kg, grinding 5kg and 10kg [5kg+]
  • Dropping 1kg, 2kg, and 5kg, grinding 10kg [10kg only]

It takes 4 ticks to mine each block (assuming a high enough mining level and pickaxe, and as long as stamina is not zero), followed by 2 ticks to grind it. There are 27 inventory spots (as one is taken by the stack of sand). Add on a few ticks to begin grinding/mining when the previous task is finished (we'll use 4 in this example - one could easily be faster though).

This does not include the double ore chance provided by the Honed perk (covered below).

Additionally, the Telekinetic Grind spell can be used to grind ore instead of manually grinding it. This essentially eliminates time grinding, though it will need to be cast once per size held. For clarity we will assume 1 tick is used per size, plus another 2 ticks of doing nothing (which can be eliminated by very active play). Additionally, the maximum number of sandstone per inventory is reduced by up to 2 as law and astral runes need to be carried (though this can be 1 if using a small rune pouch, or none with a large rune pouch equipped) - we will assume no change, using a large rune pouch.

As we are using a large rune pouch, a law staff is much less useful as it will require an additional inventory space when using an augmented pickaxe.

When using Telekinetic Grind, the time spent grinding is so minimal that grinding all sandstone is the fastest method (though one could drop 1kg for a slight cost reduction with a relatively small time addition.) Grinding everything is around 3.8% faster than dropping anything.

Without Telekinetic Grind, dropping 1kg is the most optimal method by a small margin. This makes sense, as from the buying sandstone section above, grinding 1kg is worse than any manual grinding mining method, so removing the time spent grinding 1kg in favour of more mining would increase the sand per tick slightly. By performing the optimal method one earns sand around 3% faster, which can save around 3 hours over the all method.

The optimal method with Telekinetic Grind is around 41% faster than the optimal method without.

Honed

The Honed perk provides a 2% double ore chance per rank, giving up to 12% double ore chance, and is the only such chance that can apply to sandstone (sandstone is not a core ore so has no levelling benefits, and Varrock armour does not apply). This effectively reduces the time per block mined to 4/(1+double ore chance) - or 3.5714... ticks per ore for Honed rank 6. Here follows the same table as above with Honed 6.

Using Honed 6 can save almost 7 hours over not using it. Working through other ranks (not shown here) shows a saving of 1.27, 2.48, 3.65, 4.78, 5.87, 6.7 hours as compared to not using honed, respectively.

Update history[edit | edit source]

The update history project is a work-in-progress – not all updates to this topic may be covered below. See here for how to help out!
  • patch 11 May 2020 (Update):
    • A pile of rubble that can be found during the Enakhra's Lament quest was allowing players to acquire a large amount of extra fine sand at a much faster rate. A delay has now been added to put this in line with existing methods of obtaining sandstone.
  • patch 2 December 2019 (Update):
    • Blessed sand and extra fine sand used for creating the Blessed Flask are now tradeable.
    • Experience for grinding sandstone and blessing extra fine sand has been increased to 7xp per.
    • Blessing extra fine sand now requires level 20 Prayer.

Trivia[edit | edit source]

  • The examine text is a direct quote from Star Wars Episode II: Attack of the Clones, in which Anakin Skywalker says to Padmé Amidala that he doesn't like sand, talking about his experience with sand on his desert home planet of Tatooine.
