Encalmo Goblet

Here's the 3rd goblet. The first one that has some color in it. This was made with a technique called encalmo, where multiple sections of tubing are joined together. In this case, its two sections that are both clear tubing, with a ring of yellow in between. Unfortunately, when I joined the sections together, I forgot to make sure that 1 of the ends was open. This means the entire length of tubing was sealed off, which causes the heat inside to expand, until the tubing pops - in this case, right at the seam, making the yellow ring bubble in a couple spots. Remembering to open an end would give a much cleaner look. Guess this is one of those mistakes you only need to make once and then you will always remember!
