Hi Melissa!

I've been making sidewalk chalk for quite a few years now...it
happened by accident in the beginning...as I was just trying to save the
sinks from left over plaster of paris. I poured the extra plaster into
small portion cups (the kind your lunch program might use) or any thing
that is disposable...let it dry and peel away the cup. After realizing
that these plaster scraps made great chunks of chalk, we tried mixing in
liquid tempera (this seems to work best immediatly after the plaster has
reached it's saturation point) I just give it a big squirt...less paint
gives pastel like colors (a great way to introduce tints)...more paint
btighter hues...we also discovered marbling the colors (pouring two or more
into the small cups)makes great crazy chalk.
I really enjoy ending the year with playground murals, body
tracings, sidewalk gardens, river pathways...the posibilities are
endless...not to mention the less we are in the artroom at the end of the
year the less we can add to the existitng mess.
The downfalls of this plaster method is the plaster mixing
itself...health concerns and of course using plaser outdoors could raise
some environmental concerns...does any one know if this is harmful, as the
chalk itself really isn't too dusty?

Good luck,
