I had used chalk before to make the lettering stand out, until I found out that it damages the headstones; so now I will use snow, lol!

How does chalk damage a headstone?

It is considered vandalism in some states, and the use of chalk is discouraged by grave restoration experts.
A NOTE ABOUT SHAVING CREAM, FLOUR OR CHALK
A word of advice, DON'T use shaving cream , chalk, flour or anything else on tombstones!. These have many ingredients harmful to tombstones (like butane) and in some cases can be abrasive. There are a number of websites that promote this method, with one going so far as to assure that the shaving cream will not harm the stone. Please do not attempt this as you WILL be causing a great of damage to the stone and even by washing it after you are finished you will not remove all of the material that you have placed on the stone. More detailed information on why not to use shaving cream on a stone can be found here.
In the case of flour, Daniel H. Weiskotten [weiskotten@erols.com] states that "introducing a starchy organic material to the stone is a death nell for it. it not only will feed the lichens that are there but will introduce new ones which will have little natural competition. Also, wheat paste, which the flour essentially becomes when that first rain pours down (or the first dew forms) is a great adhesive. Just because we can't see any of it doesn't mean that it is all gone. Those little fungi and microbes love that sort of stuff and it is best not to introduce anything to the surface of the stone."
According to the Crayola website, Molded chalk, such as Crayola Colored chalk, is a softer chalk, made of plaster of Paris, which is defined as quick-setting gypsum plaster consisting of a fine, white powder, calcium sulfate hemihydrate, which hardens when moistened and allowed to dry. Sidewalk chalk is much harder than regular chalk; in fact, will actually scratch a typical chalkboard. Saving Graves received the following response from Crayola concerning the use of sidwalk chalk:
"Crayola sidewalk chalk contains plaster of paris which has a gritty texture. Plaster of paris is not considered to be biodegradable, nor are most of the pigments contained in Crayola sidewalk chalk. Also, product packaging warns of colorants that may stain. This could be a good factor depending on the exact nature of what you are trying to do. While packaging does warn of colorants that may stain, chalk used outside generally washes away because of extreme weather conditions and excessive rain. Again, this could vary depending on the surface it is applied to."
