This is how I practice glazing the pears. It is just on a scrap strip of 300 lb Arches paper. I never waste any scrap of this paper. I can always paint something on the scrap and make a "snippet." I love the 300 lb and even though it is much more expensive I try to watch for sales and buy it then. Dick Blick is usually the lowest but Jerry's Artarama and Cheap Joe's are great too.
My try to paint the pears so they will appear to glow in the light. A lot has to do with the paint colors too. Here are the 3 main colors I use:
Windsor Yellow---Windsor Newton
Quinacridone Gold--Daniel Smith (WN has a good one too)
Quinacridone Burnt Orange--Daniel Smith
I also mix up a shade color.
