Thanks for answer and link.
Sword, you're first post mentioned 500ml of ionic silver then adding:
1(heat)
2(1/10 dw/glucose syrp 1 drop)
3(1/1 deionized w/glucose syrp 1 drop)
4(150 mg maltodextrin)
5(1/10 deionized w/glucose syrp 1 drop then added 20 mg vegetable gelatine)
The only one from that list that would stand a chance in a salt test would be the gelatine but given that you are using vegetable gelatine, I don't know how well that would cap the reduced silver anyway.
