There are two important forms of calcium; calcium citrate and calcium carbonate. It has absolutely no siccative qualities, it seems to actually slow drying. The urinary calcium following calcium citrate load significantly higher (by 20-66%), whether expressed as the total amount or as the increment above basal (fasting) excretion. Calcium carbonate is a carbonate of calcium that has the chemical formula CaCO3. I have contacted many people about this and the over all consensus I have gotten is that in the despite years and years of testimony, PURE basic lead carbonate does not act as a siccative on drying oils. We can obtain pure form using a pure quarried source such as marble.

Don’t want to waste the money. I do not think that the very small variation of the proportions that would be still called basic lead carbonate could account for the drastic differences in drying time. Oil primer is pricey… that’s the only reason why and I wanted to try it once, but if I buy a pint for 20-50 and if I don’t like it, I wont use it. I think I will buy the SP lead primer then. I realized last night I may have added too much marble dust to the mix and so I did two things. The key difference between calcium carbonate and calcium bicarbonate is that the calcium carbonate molecule consists of Ca, C, and O chemical elements whereas calcium bicarbonate consists of Ca, C, O, and H chemical elements. Fourteen normal subjects took 1000 mg calcium orally as calcium citrate or calcium carbonate. There would be too much lead salts in your paint. Thanks for that. However, the concentrations of these ions depend on the pH of the medium, which means, different ions predominate at different pH values. I had all ingrediants here to make my own, so I’m not sure why it’s difficult. Calcium bicarbonate is carbonate of calcium having the chemical formula Ca(HCO3)2. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry. The traditional belief that lead white is fast drying was based on impurities in the basic lead carbonate, like lead sulphate and lead monoxide which are siccatives. 4) I acknowledge that the idea of producing our own materials, as old Masters did, is fascinating (and cheaper), but the readymade is still the best: tested in a laboratory, and produced with industrial equipments. The amount of calcium absorbed was estimated from the rise in urinary calcium. Toida T(1), Fukudome K, Fujimoto S, Yamada K, Sato Y, Chiyotanda S, Kitamura K.
