Some of these are made based off of others ideas above and then others are ones that have not been mentioned.
Images A-C obtained from identifying the plants:
A is a cotton boll. If you get enough cotton perhaps cloth, gauze, or other such items could be made later.
B is a batch of flax or close enough in design to also be straw. If enough flax is gathered then natural paper could be made (It would not be white paper since that takes bleaching the fibers).
C is wheat, two products could come from wheat, flour and straw.

F is a grinder, used to grind seed or other items
G is a stone tablet, made from memory stones or can become an enchanted stone tablet by using numerous spell stones. The difference from normal memory stones is that it can record all the casts that a player has and an enchanted stone tablet made with spell stones records all the casts in each of those stones.
H is a flask of liquid fenths, used to substitute higher level resource in the creation of useable items.
I is a glass dome where you have to have a specific number of glass. The dome can be used multiple times to protect a resource from being harvested.
J is a smelter, melt down minerals, sand, glass, or fenths into higher level resources.
