As the name suggests, the Staffordshire Black Twin Pack contains one 500ml bottle of Staffordshire Black Ebonising Juice and one 500ml bottle of Staffordshire Black Tannin Juice.
 
Ebonising Juice blurb:
Reacts chemically with tannin to change the colour of wood at a cellular level.
 
Although Staffordshire Black Ebonising Juice can, in theory, be used as a standalone product on timber with a naturally-high tannin content, it is strongly recommended to apply it over at least one coat of Staffordshire Black Tannin Juice. This will supercharge the existing tannin content, thereby maximising the effect of the ebonising process.
 
We're painfully aware that that sounds like sales BS, but it's really not. We just want you to get the most out of your Staffordshire Black!
 
Tannin Juice blurb:
Supercharges the tannin content of wood as part of the ebonising process.
 
Recommended for use on all wood that is to be ebonised, Staffordshire Black Tannin Juice is essential for timber with a low natural tannin content because without it... nothing will happen.
