You can take your chalk and go climb a mountain…
No, seriously. Take it and go climb a mountain.
Did you know that climbers use a substance called ‘liquid chalk’. The purpose is to put it in their hands and improve their grip. Why does this matter to you? Because it is just that — liquid chalk. You know, like you use in marker form on your chalkboards.
Chalk ink markers are pricey and sometimes don’t come off. Yes, I know they make clean strong lines. I like that too, but I don’t like when it takes 20 minutes to clean them off my chalkboard. Using chalk you already have, and a household item on hand, you can get that same look for way less.
The way this works, in very loose chemistry terms, is that when the chalk (calcium carbonate) is mixed with the isopropyl alcohol the alcohol will evaporate at a quick rate leaving behind just the powdered chalk residue.
The evaporation rate is why you want to use 70% alcohol. Any higher and it will take much longer to evaporate – messing with your mixture.
- Non-toxic chalk
- 70% isopropyl alcohol (first aid rubbing alcohol)
- coloring (optional)
I make just enough to use at a time, because storing it in liquid form is difficult.
Start by adding 1/2 tsp. of alcohol. Get some little hands to help you stir.
Add more alcohol if needed. What’s most important is that you get a thick liquid. Almost like a white glue thickness.
I use white chalk and add coloring. You can use colored chalk, but the color doesn’t seem to come through as well.
Now the fun part! Choose your application.
1. If you are a painter…
2. If you like stamps…
You want a very thin layer on your stamp. Too much and it will not stamp correctly.
3. If you prefer a stencil guide…
Here is another post about stenciling with dry chalk for more tips.
Now, go enjoy liquid chalk and maybe paint some mountains instead of climbing!
