I have come up with another theory, which plays off of some information already suggested. Playing off the idea that each altar is slightly stronger than the last:
focus 1 = "1 point"
focus 2 = "2 points"
focus 3 = "3 points"
focus 1 + focus 2 = 3 points... "aspect 1"
focus 3 = 3 points... "aspect 2"
We know that it takes two focuses to create an aspect, and that its possible to have "magma I" and "magma II" on the same item. While it's true "Magma II" may not be created from another aspect but something else entirely, for the purpose of my theory I'm going to assume it is.
With that in mind, two focuses somehow need to be added at the third altar. This has been suggested previously, but as most things follow a pattern of some sort that we have seen thus far as crafting is concerned, I didn't see a pattern to this idea and was looking for one. (I tend to think along the lines of patterns and structure when problem solving anyway, so my theories tend to revolve around such.) Equating a numerical value to each altar of +1 over the previous one allows for 3 points per aspect, if you will, which establishes a point value necessary to create an aspect. If there are two aspects, their point value, if you will, should be equal to each other. In this case, that works.
Now following that, and using the same point value for focuses if we assume again that
an inferior focus has a value of 1 point
a focus (medium) has a value of 2 points
a superior focus has a value of 3 points
Now if we are going straight air, air, air you would use inferior air, focus air = 3 points air (focus 1), superior focus air = 3 points air (focus 2).
But, if we are going magma I and magma 2 you would use for example, inferior earth, focus fire = 3 points magma I (focus 1)
and inferior earth, focus fire again at the third altar for 3 points magma II (focus 2)
(It's possible also that since the first aspect use a smaller amount of earth than fire to create magma I to maintain the balance for magma II you would need to go inferior fire, focus earth for magma II, but I'm not sure if that would matter or not.)
So, it may be we have to use a inferior focus and a "medium" focus at the third altar somehow. As for how to combine them, your guess is as good as mine at this point.
Again, this is just a theory.
