Looks like we need to figure out the source for the new items. None appear in my crafting log when I set the filter to Recent Recipes.

The ones displayed in the patch notes screenshots are listed on the Marketboard so they can be traded. Their tooltips state Shop Selling Price: None so they aren't a vendor item. They can all be dyed.

The item names are:

Spice Rack
Adventuring Pack
Glass Jars
Wooden Plates
Wooden Cups

Uznair seems a likely source though I wouldn't discount Pyros.
