discharging to white

Although most black fabrics discharge to tan while using bleach, it is possible to discharge it to white. Thanks to Laura Kemshall I found the proper fabric to do this. It is called H200 and is sold by Whaley in the UK.
Here you see some of the fabric I discharged today:

All pieces were fanfolded and different clips were used for clamping. For bleach I used different types of household bleach. For the first two pieces I used Glorix, for the third Witte Reus toiletcleaner. Glorix discharges much faster than the other brand, even though it is at least 6 months old.
