Hydrated Lime Terminology?

I read an MSDS sheet for a hydrated lime product and it said that the calcium oxide was chemically bonded with water. Does that mean chemicals were used to bond the calcium oxide with water or is it refering to the chemical process of slaking? Also in the MSDS sheet silicon dioxide and magnesium oxide were listed. I know similar compounds are found in limestone but I wanted to make sure these weren't out of the ordinary as I'm using the slaked lime to make as natural a milk paint as I can. Thanks!

A google search of "milk paint" turns up a formula using hydrated lime found commonly at retail.I believe what you have found is fine.

Type S lime is double hydrated, i.e. it is already "slaked". It can be used as is for most applications. What is yours.

He;s making milk paint and according to various web sites using common builders or agricultural hydrated lime will work.
