Check your version first
Record your build number before comparing a recipe with a guide. Read the linked update’s date and look for any later correction.

We have not verified a complete purification recipe, quality thresholds for every buyer or an optimal profit route. This page covers the developer-confirmed changes above. Check the linked notes before using numerical advice from an older guide.
