Hi Canuck girl
The first photo is a picture of Lining powders. These came in various grades, some so fine that they are like paint when they get on your skin. They are actually metal. They can be mixed with different mediums, but usually varnish and were used to high lite decorative paintings om antique furniture. The most common method of use was to apply a thin layer of varnish over the area to be treated, let it tack up and apply the powder on the varnish with a soft piece of fine leather on a home made finger cot for want of a better word. It,s been a long time and my memory is fading.
The second photo looks like a bunch of lacquer sticks. These are used to repair scratches etc. on fine furniture. Heat up a knife, melt a little of the appropriate color onto the knife and apply to the damaged area. I believe that Lee Valley still sells these.
