H.DUPONT SERTI METALLIC GUTTA
Water based gutta ready-to-use. Use a medium-sized nib: not too small (or the gutta will not make a sufficient barrier) but not too large (there is a risk of peeling). Apply the colours once it is completely dry. Fix the gutta by ironing for 3 minutes at 150ºC on the reverse of the silk. Available in a 30ml tube in 4 different colours. Price per tube.
