You need notions of quantity, and concentration to ensure mixing two identical potions together produces a double-mass of potion, rather than a single mass of double-strength potion, and also that mixing potion A with concentration 0.5 and potion B, identical except its concentration is 0.7, gives you a double-mass of potion C, identical but with concentration 0.6. > > A minor weakening agent (-3) that also a *really* effective sleeping > > draught (17), and reduces physical dexterity (-5). > > First off.

Having specific effects would be nasty by virtue of the sheer volume of coordinates required.

Not necessarily water - but something unremarkable perhaps. Something with very high values for everything might be very acidic, and a good magical electrolyte, but unremarkable otherwise. Negative values are merely the reflection of positive ones - ie, a very negative acidity would be a very positive alkalinity. > > The reason for doing a coordinate system rather than a flat expression > > for each axis is that it allows you to put in break values.

If X is less than Y, it does this, but if it's larger than Y, it does that.

This is bringing in another issue - that of external influences on reactions (eg magical chants, special instruments, etc).

There is, but it's really a non option if you intend on any amount of chemicals, or chemicals that do not have to be centrally registered. > marian > -- > Yes - at last - You. I Choose you.
