I want to make an expendable "pearl of power" alchemical item.
Mage Powder, 35gp, Craft DC 20 - Sprinkle on a spellcaster, and it covers one used 1st level spell slot.
More costly than a scroll, but arguably less useful because you can only get spells you already have prepared. On the other hand, more useful than a scroll because you have some kind of control over which spell you get. On the third hand, less useful than a scroll because you have to wait a round to get the spell back before you can cast it. If I want a healing spell now, Mage Powder does no good.
