Dyeing Linen Blue with Indigo

To 6 bucketfuls of water take 4 handfuls of bran, 2 handfuls of glasswort, three handfuls of unslaked and lumpy lime. First bring the water to a boil and then put in the caustic, either 2 pounds of wine lees or 2 pounds of potash or 2 pounds of woad ashes, which one of these three you wish, but the potash must be ground and stirred. Let boil together for one-half hour, and then put in bran and glasswort and then the lime. Let boil again for a quarter of an hour and after it has boiled, still it with a bucket of cold water. Stir it and take the fire away. Let stand for half an hour until it settles. Afterwards strain it off until you reach the cloudy part. Throw (the cloudy part) away. Thus you have the 'Weinstein' as it is called [by indigo dyers].
