Everything Under the Moon

Just some ideas on using one of the witch's signature tools ...

Use as a fire-safe pot to hold fire for outdoor rituals
Use to hold Water in the West, loose Earth at N, Fire at S, or Incense at E for an altar or circle setup
Use to hold food/drink offerings on the altar or during ritual
Use for scrying, filled with water & catching the full Moon's reflection to make Lunar Elixer
Use to brew potions right on the stove
Use to bake bread (Pillsbury In-a-tube rolls are easy, grease well & adjust to size of pot)
Use as a container for charging tools, potions and spells
Use for transformative fire magic, as a fire-safe container for small burning tasks on the altar
Use as a fire-safe candle container to allow candle spells to finish their burn
Use as a center piece filled with pine cones & needles, oak leaves & acorns, flowers in season
Use to melt snow for a Winter Solstice rite or to hold spring water at Summer Solstice
Use to hold the coal & loose powdered incense; put sand in bottom to absorb heat (pot gets hot)
Use as a mortar & a hefty spoon as pestle

Use to build & hold a complete spell assembled just like "cooking":
. Dress the pot inside with an extra virgin olive oil for victory, or an "intention" oil
. Add the densest materials of the spell ingredients such as stones, woods, barks, grains
. Add the lightest materials of the spell ingredients such as leaves, flowers, powders
. Add the "flavoring" such as a paper sigil, paper petition, photo, tag-locks
. Set your intention and put the lid on (use a plate if there's no lid)
. Repeat thrice: "Earth, Air, Water, Fire; work you now to my desire."
. Wrap your Witch's Measure cord around the outside of the pot to "simmer".
. Serve when ready: remove nonflammables & burn the flammable remainder in the pot.
. Scatter ashes to each of the 4-winds & say: " And may it harm none. So now it is done."
. Wash & recycle reusable items.
. Wash the pot out & dry thoroughly; rub on a thin coating of oil to prevent rust.

For me the cauldron is the most sacred tool in the chest.
It can represent the center or fifth element ether ie; Spirit, It is the vessel from which all life is born anew. To drink from the cauldron is to be imbued with scared knowledge, the knowledge Cerridwen intended for her son. That was stired for a year and a day only to have drops of this sacred brew fall into unintended hands. The story the follows indicates that we can change form from this life to the next and is the Celtic myth of rebirth.
I have several cauldrons, but most usually use one for incense.
Tired for now...bu-bye

Cauldron cake (mug cake). Use large tea lights to heat.

I know it's so weird but I boiled a emu egg in mine just for fun.

Thought of making something like gumbo in a bigger one during summer.

I also bought a set of dried herbs from ebay to start me off. However cheap iron rusts really badly and vinegar corrodes it badly too. Your previous spell ends up stuck to it and leaving it outdoors rusts it away. So, yeah had that problem. I tried drying it well but it still kept turning. Am thinking perhaps putting it in a really hot fire might help it.

Iron needs to be seasoned before first time use then again after every use that involves liquid and if it gets wet it will need steel wool a good dry and re-seasoning. https://www.wikihow.com/Season-Cast-Iron-Cookware Besides vinegar tomatoes are notorious for eating at iron, do not let sauce sit for long periods it will leach iron into the sauce, possibly giving one an iron overdose.
Once it has been rusty it's hard to keep that at bay. But it will last a good long while if treated well.

Fun fact: they used to think tomatoes we're poisonous, in part at least because they would get lead poisoning from cooking them in iron pots or eating them off pewter plates.
