More Blocks was released under zlib/libpng for code and CC BY-SA 3.0 Unported for textures, see LICENSE.txt for info.

Additional changes by VanessaEzekowitz in July 2013 to take all items 
out of creative inventory.

August 2013 -- Jeremy Anderson tries to get this working after the new color
changes, and to resurrect the craft recipes. Still GPL'd as far as I'm concerned.


August 2013 -- rewritten a bit by VanessaEzekowitz to further condense the code.

==============================================================================


Recipe for standard colors:

dye
super glow glass
super glow glass
super glow glass


Recipe for pastel colors:

light dye
white paint
super glow glass
super glow glass
super glow glass


Recipe for faint colors:

light dye
white paint
white paint
super glow glass
super glow glass
super glow glass

recipe for low-glow-stained-glass:
as above, but substitute 'glow glass' for super glow glass.

recipe for no-glow-stained-glass:
as regular stained glass, but substitute plain 'glass' for super glow glass


All recipes produce three stained glass blocks.
