How Do You Make a Glaze with Bubbles? (What Is Bubble Glaze)
There are several ways to glaze your pottery work. You can either use an actual glaze or you can bubble with an underglaze. The actual glaze is available in many colors. On the other hand, underglaze is a category of paint used in pottery.
Some of the artists take a bisque-fired piece of pottery and dip it in white glaze. Next, they mix another glaze color with dish soap and create bubbles using a straw. Similarly, other craftsmen bubble glaze the bisque-ware first and then cover it with a clear glaze.
On the contrary, other artists work with underglaze. As I mentioned above, underglaze is a special category of paint that is used to decorate pottery. It is heated in a kiln and undergoes a chemical reaction to give pottery work an impressive final look. The final color may change shade and is not necessarily the one you painted before firing.
I prefer to underglaze my pottery work before it is bisque-fired. It leaves beautiful patterns of underglaze on the white clay background. Finally, I cover my ceramic item with a white glaze to give a sealing effect.
I have also observed a few painters underglaze their work after the initial firing. So, there is no confined way to do the bubble glazing. Hence, I would recommend you try the process at your convenience and decide which way suits you the best.
How Do You Do Bubble Painting?
Supplies such as dish soap, cups, straws, containers, and pottery vases are essential to start bubble painting.
You can initiate the process by mixing half a cup of water with dish soap and paint. Make sure all the ingredients you use are non-toxic as children might want to drink the mixture. So keep a close eye while working with children.
Finally, keep the pottery vase in the container and let the kids blow mountains of bubbles into the vase. After a few seconds, invert the vase and fill the container with bubbles. As the bubbles dry quickly, you can remove the vase from the container to check the unique patterns on your pottery work.
There are scenarios when bubble painting can lead to some defects in the patterns. One of the pottery glaze defects is known as glaze blistering. So, what happens in glaze blistering and how can you avoid it?
What Is Glaze Blistering?
Blisters are created on the fire glazed surface due to the remnants of bubbles that have burst during bubble glazing or painting. These blisters can vary in size and tend to be bigger in size where the glaze is thicker.
Sometimes, blisters and blebs are formed due to incomplete clay preparation. Other reasons for such faults are the presence of materials like borax, boric acid, potassium carbonate, and sodium carbonate. Therefore, it is suggested to replace them with other fluxing agents.
In case you are bisque firing your ceramics, you need to be precautious and examine if you are doing it right. It is imperative to make sure that the bisque fire has good ventilation. As the clay releases gases on oxidation, it is essential to have a good venting system to allow gases to oxidize.
Moreover, it is advisable to have a hot bisque to burn out any sulfur and make the glaze blister-free. A practical approach to bisque fire is to fire it up slowly. Also, use humidity drying equipment before bisque firing your pottery work.
