Selecting the right chalk art mediums for your project can be a difficult decision. Finding a quality product with the right surface is important. Because of the variety of chalk art mediums, it is important to determine if the substrate you are using is porous or nonporous.

Porous Versus Nonporous
Porous surfaces allow the passing through of water, liquid, or vapor. Pigment from the markers could get absorbed when using porous chalkboards. These types of surfaces include chalkboard painted surfaces, wood, paper, and cardboard.
Nonporous surfaces will not absorb water and liquids. Nonporous surfaces like chalkboard labels, mirrors, glass, glazed ceramic, slate, metals, laminates, and some plastics, will result in liquid chalk being easier to remove.
Therefore, always test your liquid chalk markers on a small portion of your medium to see if they are right for your project.

Using Cohas Eco chalkboards, our artists were able to create farm market images of strawberries, apples, and pears with the waterproof 6mm markers. Our artists also used the Zig Illumigraph markers, which are highly fluorescent and suitable for lighted signs. These markers work with a black light and glow when light reflects or passes through them.
Creative Project Ideas and Unique Mediums

Our artists at Cohas.com are always trying to use the Cohas Color Collection for fun projects. The latest project involved drawing on clear plastic ornaments with the 1mm waterproof metallic gold and white markers. The flecks in the metallic paint sparkled in the lights of the tree and are nice and opaque.
Additionally, one of our artists used a metallic marker and painted on one side of a piece of acrylic glass. The result is a colorful shiny background that can be easily cleaned with Windex. Artists can also use spray paint to complete the same effect on the back, but that would create a more permanent background on your medium
.
Finally, Cohas offers chalk artists a wide variety of chalk mediums to create chalk artwork on. This includes our chalkboard label collection, magnet collection, slate and novelty collection, and much more. For that reason, Cohas.com offers a large selection of wet erase menu board markers, and waterproof chalk markers. These markers work great for chalk artist.

Our tour would have ended then but one of the brewmasters was “taking the day off” and in house. He had to show us the new distillery operation making vodka using distilled grain from the brewpub. Made right here in New Hampshire, this was smooth but powerful when splashed over ice and sipped. Truth be told, the fragrance of the aromatic still with a steady “drip, drip” may have made most of the impact on our palate.
Like any experiment, the mistakes and errors sometimes lead to different results. We found when engineering this new chalk marker tip we could fabricate it in any size. Our technician was able to modify the Zig Posterman 50mm tip into any shape too! Modeling after the Zig Memory System Scroll and Brush marker, our lab did create a tip with a wide and thin section.

Debbie started painting windows over 20 years ago, while in Art School in Phoenix Arizona, mostly to create holiday windows for local businesses. When she and her family moved to Colorado Springs from Palm Springs, California, she saw a real void for window painting and decided to start my business here.
