The new formula features a high concentration of powder with high yield for greater efficiency. Standard aerosol food colouring sprays tend to give off a very subtle finish and can be difficult to apply to specific parts of your cake without touching the surrounding areas. Colourglo™ powder spray is in the soft metallic colour, and in a pump dispenser, allowing you to quickly and easily cover an area with your colour to achieve a concentrated coverage, hold the dispenser close to the surface. A less concentrated coverage can be achieved by holding the dispenser further away.User information: Simply hold the spray approx. 10-20cm away from the cake and spray in short, gentle bursts - move closer for specific areas.
