When crafting 6 stained glass of the same color you only get 6 glass panes. Doing so with normal glass yields 16 glass panes.
What I expected to happen was...:
I get 16 glass panes
What actually happened was...:
I got 6 glass panes
Steps to Reproduce:
1. Get 6 stained glass blocks of the same color and 6 normal glass blocks
2. On a crafting table, craft glass panes out of them
3. Notice the different numbers of glass panes you get

Yes, could be intentional, but it does not make sense (in a Minecraft way) to get 16 normal glass panes but only 6 stained ones. Should be the same, either 16 or 6.
as the model's changed.
Minecraft got ThermoPane (TM) windows...
In fact, if you have 6 blocks @ 6 faces = 36 panes / 2 = 18 window panes
Ah right, I forgot that the input is 6 blocks. If Steve were perfect at cutting glass, then you would expect 6 * 8 = 48 panes, which would have the same total volume.
Of course, that would be just ridiculous; 16 is fine.
I'm talking in terms of volume, not surface area. I always interpreted Minecraft's glass blocks as a solid block of glass (i.e. no air inside). In that case, the volume of a glass block equals eight glass panes, which is easy enough to observe when you count the pixels. A glass block measures 16x16x16 pixels on the default resource pack, equaling 4096 "voxels". A glass pane measures 16x16x2, equaling 512 voxels, exactly 1/8 of a glass block.
Of course, if glass blocks are hollow, then only the faces count. In that case, we'd need to know the thickness of each face to figure out how many panes it could make. If each face is 2 pixels thick, you'd have 16x16x2 * 6 - 16x2x2 * 12 + 2x2x2 * 8 = 2368 voxels. Those numbers are the total volume of each face, minus the total volume of each edge, plus the total volume of each corner - this has to be done because there's overlap. Those numbers are correct, as you get the same result with 16x16x2 * 2 + 16x12x2 * 2 + 12x12x2 * 2 (which measures pairs opposite faces, excluding volume that's already been counted). Anyways, those numbers would only give you enough glass for 4.625 glass panes, not 6, leaving the recipe to provide 27.75 panes.
I got curious and tried glass with 1-pixel-thick walls: 16x16x1 * 6 - 16x1x1 * 12 + 1x1x1 * 8 = 1360, or only enough for 2.65625 panes (15.9375 for the whole recipe). This is actually the closest to Minecraft's crafting result, so I guess glass blocks actually are hollow (which would explain why they break so easily).
Anyways, I probably got carried away here, considering I don't actually care whether the crafting recipe is realistic. Game balance is always more important than that, so I'm guessing it's just a coincidence that Mojang's recipe works well with that last formula.
Could be intentional.
