Kato Liquid Polyclay (Clear Medium) is a revolutionary product which allows users to create perfect photo transfers and finishes for Kato Polyclay pieces. It can also be used as an adhesive, grout, or glaze. Liquid Polyclays should be cured at 300F (150C) for 20 minutes for a matte finish. To create a glossier finish, cure for an additional 10 minutes at 350F (177C), or wave a heat gun over project until desired glossiness is achieved. Do not inhale fumes and never cure above 350F (177C) or allow Liquid Polyclay to come in contact with an open flame.
