Translucent blue is a beautiful onyx with variable shades and veining. Portions of this stone are semi-translucent and is ideal to be backlit with the sun, lights, candles or anything you desire. (We suggest tea-lights and not fire lit candles)
Translucent Blue onyx slabs are rich with colors of blue honey with darker blue veins. The pieces are amazing with light behind them and amazing just the way they are.

This canvas we are offering you is Calcite that ranges from a creamy pale yellow to a deep blue and amber color. It is a beautiful and impressive.  Commercially manufactured, high heat pressure treated, colored infused calcite for colored translucent beauty.  When it comes to art, let the canvas speak to you!
The awesomeness that sets this stone apart form other forms of calcite are its colors, patterns, translucency, transparency, and it does not fade as readily in sunlight as other formed of rock.  The patterns change depending upon the point of origin of the cell growth-ranging from a tight “Blue” look of small hexagonal cells grouped close together to large cell areas that give the appearance of “petrified beehive cone appearance” where cells are at their maximum growth and minimum cell walls appear. In short, these are the most amazing canvases for our paint and art!!
We suggest starting with your first one with acrylic paint.
You can always wash them if you wish. Dawn will remove any oils that may reject paint.
If you have the smooth blue onyx and are wishing you could use pencil, you can sketch it with a nail file or sandpaper. ❤
With the Onyx we like to say “less water is more”. If you find you are having a hard time getting the paint to either stick or show up dark enough on the Honeycomb, it is because you are using to much water. These are dense where other rocks are pours.
You can also put a clear coat on before you paint them. Then the paint sticks better. You should use a mat finish, then after all is painted, use a gloss finish clear.
One of our artist Lynn suggest:
Use a wetted Q-tip or toothpick and some water to touch up paint.
” I use Liquitex High Gloss Varnish for the base coats and then finish the coat for sealing with the same.
 “I do use two thin layers of Liquitex High Gloss Varnish as a base coat on the bare stone and also as a sealer after painting. The clear coat allows better adhesion of the acrylic to the surface when starting the painting and allows for quick cleanup if you need to change something”.
The clear coat over the work prevents it from scratches or abrasion, just like in the regular rock paintings.
Resin, as a finished coat, would be awesome on this stone as well. I hope that helps!
Option 2:
If you are a beginner, feel free to try a very thin layer of Mod Podge. This will give you a better feel for the texture of the Honeycomb and start you out at ease. (Please note that Mod Podge is a glue. Depending on the weather it may not be recommended within your local group. Please use wisely. The Mod Podge needs to be applied with your finger and very thin. Follow the ending clear coat suggests above after painting.
