Husband and wife glassblowers Tove Ohlander and Rich Arentzen trained in Sweden before they opened their Pine Street studio and store, AO Glass Works, earlier this year. Many families and school classes have since stopped in to watch them mold molten glass, shaping it into vases, bowls, lampshades and tiny figurines available for purchase. This fall, the couple is adding a new service: custom glassware crafted in the shape of a child's handprint or footprint. Your kids make an imprint in sand, and Ohlander and Arentzen use that form to produce the piece. Call ahead to find out what's cooking in their 2000-degree oven.
