Manual founder and creative director Craighton Berman funded this Tea Maker No.1 on Kickstarter. The minimalist tea brewer is made of slip-cast porcelain and cool-to-the-touch laboratory-grade borosilicate glass. Inspired by the Chinese gaiwan, its double-wall construction keeps the steep temperature stable. The tea maker holds 6 oz (175 ml), slightly more than the traditional brewing vessel, but offers the same control in decanting. The accompanying porcelain pitcher holds 9 oz (270 ml).
