How Calcium Affects The Printing Process – Ink & Print

Acid type paper uses 8-12% clay (an alumino-silie) as the main filler along with a rosin-alum sizing. For this to function effectively, a pH of 4.5 to 5.5 is needed which results in a sheet with a residual acidic pH (acid paper). Calcium carbonate can’t be used because it would dissolve and cause foaming.

Carbonate chemistry — Science Learning Hub

Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites.
