I want to make some of my own chalk for a larp thing I have. D&D played IRL, and you actually do the things rather than roll dice. I play a mage, and I can do 'rituals' and just to help with the rp and the mood of the game I have this awesome idea.
I need to take things such as guano, nightshade, trolls blood, elf cup, obsidian, thunder teeth, flame bud, mistany berry, perfect gems and tasloi venom which are components for rituals. They range from herbs, parts from monsters, and natural items.
One ritual I have to do is to grind up some of the stuff in a morter and pestel into an 'ink like paste' in which i will write on the person receiving the buff. And i thought it would be awesome to actually do this, and not just mime it.
So I thought hey chalk is non-toxic, can color it, and i can grind it for real in a mortar. And some of the components will need to be a liquid which is easy. I can just do food dye and water.
BUT my issue is, I want the chalk to look like what it is to be.
I want to get some clay and make little things that look like the components, and then take the clay things and make molds of them to then pour in a chalk mix and once dry BLAM I have a peice of chalk that looks like obsidian that I can toss in bowl and grind down and then use one that looks like teeth, and then add in a brown colored water to be guano to get my 'ink like paste'
BUT I have NO clue on what kind of clay to use to make the base? sculpt?
Then I also have NO clue about molds, and how to make them. So ANY tips or ideas would be AWESOME!
I'm only looking for these things to be about the size of a tealight, maybe a tad smaller. They can be flat on one side, so I'm not worried about making a two sided mold.
Also if anyone knows of a good and easy recipe for chalk that would be awesome to! I've seen a few, but most require powdered tempura paint for the color and none of the local craft places carry that, and I'd rather not have to go far. Unless someone knows someplace in Southwest Ohio that might have it.
