Using Wood Stain on Indiana Limestone

I have started experimenting with some of my limestone pieces. I have used wood stains to add a different feeling to the work. This is my second attempt. I don’t have a title for this one yet, and it is still in progress. I have to figure out how to base it. I have had many suggestions to hang it. But, that is beside the point. As you can see, this piece is not the standard color of Indiana limestone. I used a blue universal wood dye to add color. I think it is pretty cool. What I don’t know is how it will hold the color if it becomes an outdoor sculpture. That is one of the fun parts of being an artist is that you get to experiment to see what happens.
