This past Sunday, I took my parents to Shatter Glass Group in Chicago, so we could give glassblowing a try. Interesting enough already, made better by the expert knowledge of Ashley, who led the workshop. She explained about how the glass manufacturers manipulate the chemistry of the glass to allow it to be worked with at different temperatures, about the elements used to make different colors, and more. We spent two hours with an instructor, and we each created a pint glass/vase.
UPDATED: Both pictures of a glass vase are my final piece, before and after cooling.
