What is the difference between dyes and paint and which should I be purchasing for my silk work?

In my Painting Course, I only use dyes. Paints are acrylic-based and will leave a hard/stiff surface when the paint dries. They also need to be fixed by ironing (not steaming). You can get some good ‘painterly’ effects using paint. Dyes blend into the silk and do not change the texture of the silk at all. Dyes are translucent, liquid and produce very strong, vibrant colours and are fixed by steaming.
