    I hear that adding baking soda to ACC makes it set instantaneously and hard as granite. Anyone know anything about this?

    Makes sense. I don't know if there is a chemical reaction, where the sodium bicarbonate and the ACC combine into something else. But baking soda dissolves in water, so it sure could soak up the ACC. I don't know if the result is just a very tight crystalline structure or a new compound.

    I've used it to make textures on things. It's darn strong. When I was into Fantasy miniatures and military miniatures I would use ACC and baking soda to make scenery on the bases for figures.

    I think little dabs of Hydrocal would be far less expensive than tubes of ACC....?

    Waste not... want not?

    It seems that ACC doesn't have much of a shelf life once openned. I would guess that after using some of the ACC to glue stuff together, any left over could be 'experimented' with.

    So just exactly how would one go about mixing these two items together in order to get that "granite" effect... does it actually look like granite? :huh:
    How long do we have before it 'instantly sets'?;)

    I buy little tubes of ACC at a Dollar Store. At $.50, I don't care that they last only a few days. I must have used 20 tubes on my last ship project. If they won't unclog, I just chuck them. Now maybe I'll keep some baking soda nearby.

    Superglue polymerizes in the presence of water or hydroxyls (OH)-. Plenty of hydroxyls available from baking soda. It's probably pretty instantaneous, as far as instantaneous goes.

    Anyone know if the mixture gives off any heat? Superglue plus "cotton" swabs can make a bit of smoke--at least a decade ago. I think we have milder formulations today.
