Pottery Tool Set

Nihon Kyozo Co., Ltd. Raku-yaki Pottery Tool Set

As I lack knowledge, I am unsure of the names and uses of each tool and material.
There is a list (Image 16), but it may not match. Please make your own judgment based on the images.

Items that seem to match the list:
Overglaze paints
Underglaze paints
Black Raku glaze
White Raku glaze
Refractory adhesive
Turpentine (container only, empty)
Spatula
Paintbrushes, brushes
Stones
Measuring cups
Mortar and pestle

I do not know what the large amount of white powder is.
Based on the list, I imagine it might be glaze? Or it could be something not on the list.
I apologize for the uncertainty.

There are metal tools, but the knob in the center is loose.

We may change to Rakuraku Mercari Bin shipping.
