Used for the 'Serti' or outlining technique of silk painting. The clear gutta is piped onto the silk before painting as a barrier to the spread of the silk colour. When the gutta is dry Javana Silk Colour, or an alternative heat-fixed flowing fabric colour (eg Dye-na-Flow), is applied.
Once the work is finished and dried it is then fixed using the heat of an iron. The piece of work is washed to remove the gutta to reveal the original colour of the silk.
Can be applied with a paintbrush, or decanted into a nozzle bottle and used with a fineliner tip for absolute precision.
For silk and other lightweight fabrics made of cotton, viscose as well as blended fabrics with no more than 20% synthetic content.
