Developed with Dalton Maag, Tephra is a type family based on the lower-case ‘interact’ typeface designed at 8vo in 1994. The original type has been extended and updated to a set of six fonts: Tephra 0; Tephra 12; Tephra 50; Tephra 100; Tephra 138; Tephra 250. Tephra was launched with the publication of a limited edition set of six silkscreen prints designed by Hamish Muir
