Thanks. Very seriously modified. The gum of the period also seems likley to have been a powder or flakes and that would be why it needed dissolving and straining. The eco flo is an already re hydrated product so shouldn't need dissolving and may affect the volume it swells as it is hydrated and in the original recipe the 6 oz in 4 quarts of water may have make the equivalent of 4 quarts of eco flo? The glue coming as a dry not a liquid may have had a similar volume discrepancy compared to a fluid version. I think I may have to buy ss original as possible make both individually check performance and modify from there I will just scale back the amounts to make small amounts. I think this is a rabbit hole I should have left alone.
