i'm very confused... if i'm supposed to make a corn pudding
http://salemwiki.info/index.php/Unbaked_Corn_Pudding

now, assuming the water is 75 and the garlics only 2, the water has a "purity power" of 75 (and garlics 2) or the garlics are like "1kg of garlic" and the 75 water "0,75kg water"?
i'm confused about calculating teorically max purity for foods, i don't think a 75 can be like 75 "units" of 0%purity water VS 2 garlic of 5%purity...

any1 knows how that works?

Water has 0% purity and drags the end purity down alot. Some people are nagging for high purity water, but thas just crazy to make it easier to get even higher humoured chars. Im not sure about the maths behind calculating end purity, but I guess you will end up with a 1-2% purity product. Which suck.

i wantn't know what is the result... but if the 75 water is counted like a 0,75 unit (1 unit = 1 garlic) or like 75 units

Nobody has bothered figuring out the crafting equations yet. Or at least, if they have, not bothered to publish.

My observations seem to suggest that the quantity of each item does not matter, only the number of kinds of things.

Pie Dough and Oatmeal crackers made from the same flour end up with the same purity, even though Pie Dough uses more flour. The elemental composition of the flour is averaged with that of the water. With Flour that is 35/23/25/17, you will get dough that is 30/24/25/21.

Similarly for Smelting, there is a difference in Ore purity with and without Lime, but you get the same purity for 1 lime as you do for 20, though I'm not sure of how it's averaged. It's much less penalizing than water in pie dough.

The reason you see such dramatic drops in Purity when mixing ingredients is that Purity is roughly proportional to the square of the highest Element.
If you have flour that's 5/85/5/5, that's a purity of *runs calculations...* 64% with 6.76x multiplier. Multiplier = (9 * Purity) + 1
If you make it into Pie dough, it's now 15/55/15/15, with a purity of 16% with a 2.44x multiplier.

Because of this huge loss in food purity when impure substances are used, Cabbage Crumbs are considered something of a "Wonder Food" since they can be made entirely from high-purity ingredients (no water!).

The purity equation has been published on the wiki. It's very simple.

When you're making something that has three ingredients, they are all added together and divided by three. So, it's an average of the ingredients, regardless of the amount of each.

When an individual ingredient has an amount, it's averaged first. For example, pumpkin pies take one dough and three pumpkin. The 3 pumpkin pieces might be at different purities, so first they are averaged. The pumpkin piece average is then used as the quality number when averaging the pumpkin piece ingredient with the dough for the final quality.

That's why it doesn't matter how many lime you put in a smelter, because the lime is averaged together (and is always 0%) and then counted as one of the two ingredients. You can vary the quality of your iron though, if you smelt different qualities of ore in the same run.

I did some calculations, and Iron Purity is (4*Ore + Lime)/5

It's not all THAT simple. Also, the Purity article on the wiki is rather terrible. It also doesn't contain the information that we have just discussed about the relative contributions of different ingredients.

I'll have to do something about that.

thank a lot all ^^

that may be very helpful in teorically math!

In case of iron quantity of lime and ore matters. In case of standard crafts it doesn't, at least for now.

Also, it's not purity that is being averaged but alchemical components. So, if you craft something from 2 ingrredients, one being 100% pure (100 in one element) and another 0% pure (25 in all elements) you won't get 50% pure result. You will get something with 62.5 in one element and 12.5 in 3 others, giving something around 25% purity

The quantity of Lime does not matter, only the presence/absence. There is no difference in purity when using 1 Lime or 10. When Lime is used, the Ore has 4x weight in the element averaging.
