Compiling these all in one answer in the order the objects are listed in the table in Chapter X. Credit for most of these goes to kiera1234
i. The Flaming Sword: Chapter IV, the sword behind the wizard on the left page has the symbol.
ii. The Bountiful Basket: Chapter I, the basket with the skull on it has the symbol, in the picture with Merlin and Harpier.
iii. The Horn of Delectable Drinks: Chapter VII, on the unicorn picture, on its horn is the symbol.
iv. The Sweet Chariot: Chapter VIII, the chariot in the border on the bottom of the right page has the symbol.
v. The Handy Halter: Page with the map, under the fold out on the right. The horse in the bottom corner's halter has the symbol.
vi. The Notable Knife: Chapter XII, underneath the athenor where the whetstone and knife are, they have the symbol.
vii. The Capital Cauldron: Chapter IX, on the donkey apprentice picture the symbol is on the handle of the cauldron.
viii. The Wonderful Whetstone: Chapter XII, underneath the athenor where the whetstone and knife are, they have the symbol.
ix. The Commodious Coat: Final page, the tip of Merlin's coat near the center of the page has the symbol. Many people think this is the cloak of invisibility, but I disagree, see my note under xiii for my theory on that.
x. The Pleasing Pan: Chapter VI, the common wizard familiars picture, the bowl with the food in it has the symbol. Decide for yourself if this is the pan or dish.
xi. The Pleasing Dish: Chapter XIII, the Paracelsus Picture where he's holding the pot, it has the symbol. Decide for yourself if this is the pan or dish.
xii. The Champion Chessboard: Chapter III, on the tile in front of the fireplace there is the symbol. This is the corner of a chessboard on the floor.
xiii. The Cloak of Invisibility: Title page, above the words "The Book of the Secrets of Merlin." I believe this is intended to be the cloak of invisibility because you should not be able to see the cloak if it's invisible. Or this symbol could be nothing and the you can't find the cloak because it's invisible. I think it's a joke on the reader to make this task as impossible as "relocating a mountain or balancing two nails tip to tip," like mentioned in "The Wizard's Test" in Chapter I. However, I could be wrong, that's just my theory.
