"Thank you very much."
And then she gets to work.
The first step is to isolate the Tylendel-stuff and Gala-stuff from the rest of the ash. She fills the bucket, purifies the water, and fills several pieces of glassware partway full, then refills the bucket again just so she won't have to stop in the middle of something for more water. She carefully funnels the contents of the urn into a larger piece of glassware, then rinses the urn with purified water a few times to ensure she gets the maximum quantity of relevant ex-biomass. She stirs the container, evaluates the thickness of the current mixture, adds some more purified water, then sets it to heat. Then she washes the funnel, positions it over an empty piece of glassware, makes sure everything is stable, and then, carefully, over the funnel, bites her wrist open.
Once the glassware is full of ichor, she allows her wrist to scab over, then washes the funnel again. She checks the temperature of the water-and-ash mixture and takes it off the fire. She dips her finger in a beaker of purified water and draws a sigil on the table, then sets the mixture down on top of the sigil. She lets it cool like that for a moment while she measures out a handful of the first chemical, then pours it into the beaker. The contents of the beaker immediately turn a bright red and fwoomf out a ring of smoke in the same color. She nods and sets it over the fire as she measures out and mixes more dry ingredients and the beaker slowly changes to a dark purple. When it darkens so much it's almost black, she takes it off, places it over another water sigil, adds one of the mixture piles, stirs it some more, lets it sit for a while, and then pours it through a filter into another piece of glassware, discarding the sludge left on the filter.
She repeats variations on these steps for several hours, until finally, shortly before noon, she smiles triumphantly and puts what's left on the filter in another piece of glassware, adds some more water, and sets them both on the fire. She stretches, goes out to the pump to wash, and goes looking for lunch.
