Below are most of the sites I visited. Forgive me, I have yet to learn how to put links on here (or anywhere else for that matter). I will give you the names of the blogs I visited though. I think all of them have a tutorial on how to make the colored glass, but each one is a little bit different.
This was my attempt at putting the mixture inside of the bottle. It takes patience to swirl the color all around the bottle evenly & then to get all the excess color out. It also takes quite a while in the oven at a low temp to get it to dry. I was not patient on steps 2 and 3 that I just mentioned and as a result we got some gloppiness going on here. I ended up having to spend time soaking the bottle in hot water and getting it all out after it had dried. I ended up using a wire hanger to do that job! My daughter was grossed out by the glop but I was a bit fascinated.
And here they all are on my mantel. (Please don't judge my mantel....I don't have very strong decorator genes, but I'm working on improving what I do have.)
So, there you have it. My first attempts at colored glass. I'm pretty sure I will do it again in the future! I've already had my eye on several clear glass objects in my house...such as a vase on top of my bookcase and a votive candle holder in my cupboard.
