I tried to make a larger batch with less water (but same ratio of washing soda and maltodextrin to gold), which I thought Kevra, you had mentioned having done elsewhere successfully using the maltodextrin method. I used the equivalent of 50ml per 1.25ml of gold (just a larger batch). Initially when I added the washing soda solution, it did turn red, but now after heating, stirring, heating, stirring, etc. it's turned super dark purple again. Anything I can try to get the gold to curl up and form the nanospheres and be red? I'd be bummed to lose the gold I used.
