Potions- Week Eight

Chapter 49

Lesson Eight

Lab #2: Forgetfulness Potion 

Estimated Brewing Time:

  • Pewter Cauldron: 60 minutes
  • Brass Cauldron: 51 minutes
  • Copper Cauldron: 45 minutes

Ingredients:

  • 2 drops of Lethe River Water
  • 2 Valerian sprigs
  • 4 mistletoe berries
  • 2 spoonfuls of honey OR 2 standard measures of mint leaves (optional)

Instructions:

  1. Take your dropper to add 2 drops of the Lethe River Water to your cauldron.
  2.  Heat your cauldron to 394 Kelvin (that is 121°C/250°F) for 20 seconds, then turn down the flame.
  3. Add the 2 Valerian sprigs to the cauldron, then use your wand to stir your cauldron clockwise 3 times.
  4. Leave your Potion to brew in your Pewter Cauldron at 318 Kelvin (45°C/113°F) for 30 minutes. During this step, the Potion will be a deep blue and is likely to emit red sparks. (This would be 25 minutes in your Brass Cauldron or 22 minutes in a Copper Cauldron.)
  5.  Add the 4 mistletoe berries to the mortar.
  6. Optional step: Add the 2 spoonfuls of honey OR 2 standard measures of mint leaves to the mortar as well.
  7.  Grind with pestle until the ingredients are thoroughly mixed and the solids have the consistency of a thin powder.
  8. Add 2 measures of this mixture to the cauldron and stir with your wand counter-clockwise 5 times.
  9. Let the Potion finish brewing for 20 minutes. (This would be 16 minutes in a Brass Cauldron or 13 minutes in a Copper Cauldron.)10. Take your Potion off the flame entirely. The Potion should now be a glimmering orange-red, and will still occasionally give offsparks. It will smell like any additive you may have used (honey or mint). If you did not use one, it may smell a little bit like burnt cinnamon.
  10.  Stir the Potion to ensure it is of uniform consistency and then transfer it to one of the glass phials. Remember to properly label the phial as we have discussed.
