How to make Barley bread?

I started experimenting with baking using mixture of wheat and barley. The loaf was very tasty when made this way.

1. 
   

   Barley is one of the grains that has gluten. So is there a recipe for bread with only barley?

   
   


2. 
   

   In my experiment, I added 2/3^rd wheat and 1/3^rd barley flour. What is the maximum amount I can substitute, if pure barley bread can't be made?

   
   

I want the bread to raise nicely and have normal texture.
