This set from Daler Rowney includes 5 tubes of popular acrylic mediums, ideal for creating special effects with all acylic colours. There is also a short project sheet to get you started.
Impasto Gel (1 tube each of gloss and matt): White, translucent heavy bodied gel to create textures, dries to a matt or gloss finish, ideal for covering large areas with heavy bodied acrylic colour.
Glaze Medium (Gloss): White, translucent cream that increases the flow and transparency of acrylic colours to produce a fine glossy glaze. Can be used as an adhesive glaze medium perfect for collage, decoupage onto wood, board or even flat stone.
Pearlescent Tinting Medium: Gives a pearly metallic lustre when mixed with acrylics. On its own it dries to an attractive off-white pinkish pearlised colour - works well on dark and light surfaces.
Slow Drying Gel: Slows down the drying time of acrylics. Increasing proportions of the gel will increase transparency and reduce viscosity.
