Printmaking

I have these thick glass panels that I got at the recycle center and have been trying to figure out how to use them in the art room. 

I decided to try printmaking.  I used tempera paint and spread it out evenly with a brayer.  The children were able to use tools such as combs, sponges, and brushes to create lines and patterns in the paint.  We then put a piece of paper over the paint and lightly pressed down allowing the image to be transferred onto the paper.  It was an interesting first try however, I don't think tempera paint might be right for the job.  It's too slippery and not tacky enough.
