As 9-year-old Naman Kotian waited for his mom and his sister to finish their own glass beads, he clutched his safety goggles in [link widoczny dla zalogowanych] his hands. He had to wear them “so the fire won’t spark in your eyes or anything.”Naman, along with several other kids, made his own glass bead with the help of local glass artist Abby Gitlitz and the WonderLab staff.WonderLab sponsored a workshop called Changing Glass in its February “Forged by Fire” series.Three local glass artists demonstrated decorative fire-blown glass-making techniques.WonderLab sponsored the Forged by Fire series to show how creativity in arts and sciences is connected.
Before the kids set to work on their glass beads, Gitlitz used cookie baking metaphors and honey to explain what happened to the glass when the kids fired it. “When I work with this glass it gets four times hotter than the cookies in your oven,” Gitlitz said. She then pulled out a [link widoczny dla zalogowanych] jar of honey to demonstrate what happens to glass when it gets hot.“Glass moves as much as honey when it’s hot,” Gitlitz said, swirling a jar of honey.The honey was the same consistency as hot glass. A straw in the honey jar mimicked the steel rod the kids used to wrap their hot glass around and make their bead. She pulled the straw out and twirled it to form a bead of honey on the straw.
Gitlitz told the group how to make glass rods colorful by using different chemical additives. Two fat selenium and copper sticks, which looked like giant crayons, are used to turn glass yellow and green.“It’s like food coloring,” Gitlitz said.Gitlitz asked her audience to act out [link widoczny dla zalogowanych] what happens to the glass when the kids dropped their beads in water to cool.
