You can freely express your creative side and mix different powders in the QJAR. However, there are one or two things you should bear in mind.
Powders with different densities and chemical properties can become unevenly distributed in the container during prolonged storage. For example, one molecule may sink to the bottom while another concentrates on the surface.
If you then take a spoonful with your QSCOOP, accurate distribution and precise dosing can no longer be guaranteed. This phenomenon is referred to in technical terms as a lack of homogeneity.
Regular mixing can minimise the problem, but the desired accuracy for precise dosing cannot be achieved in this way.
