You have to turn on blending, I think.

maybe something like this:

glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glEnable(GL_DEPTH_TEST);

But with blended trinagles you should proceed the following:

1. draw all non-transparent primitives
2. code above
3. draw your transparent primitives depth-sorted(furthest first, nearest last)

if primitives are texture-mapped or not doesn't matter.
