Harcuba is a master etcher. This week, he was etching on pieces made by Novotny and by the museum Hot Shop crew. He starts by making a drawing on paper, often a napkin, then uses a Sharpie to make the drawing on the glass. Then he etches the design on the glass. (It sounds a lot simpler than it is.) He works on a dozen pieces at the same time, going back and forth between different pieces.
Hot Shop visitors who sit in the front row of the gallery often have a chance to speak with the artist and ask questions, which is great fun.
In addition to making pieces for Harcuba to etch, Novotny (red shirt) made some of his own pieces. He called this one a "cage," although to me it looked like a basket or like this Knotted Openwork Scarf stitch — in glass.
