How do you make a bubble underglaze?
Mix 3 Tablespoons of water, 1 Tablespoon of Underglaze, and 2 to 3 squirts of hand or dish soap in your cup. Never pour too much into your cup at a time, because whatever you put into the cup won’t be suitable for future use. Once you have the water, soap, and the underglaze in the cup, mix well.

How do I stop my glaze from bubbling?
Glaze melts are not homogeneous (especially in the early stages of melting) and a beneficial side-effect of the bubbles is their mixing action. This produces a glass of less phase change (and therefore more even refraction). Bubbles can often be greatly reduced by and drop-and-hold firing schedule.
Do air bubbles make pottery explode?
The Myth of Air Bubbles “If you create an enclosed form, you need to poke a hole for the air to escape or it will explode.” While it’s true that enclosed pockets of air in your clay can lead to explosions, the explosions don’t have anything to do with air being trapped and unable to escape.
What happens if there is an air bubble in clay?
Dangers of Air Bubbles in Clay Air bubbles in clay items are dangerous because they can cause explosions in the kiln. The air bubble dilates due to heat and forces the clay to crack or explode and shatter the ceramic piece. The risk of explosion increases with the temperature in the kiln.
Why is my glaze cracking before firing?
When a glaze cracks as it dries on a pot, it usually means that the glaze is shrinking too much. This is normally caused by having too much plastic material (ball clay) in the glaze. It should be added while the glaze is still a powder. The addition of CMC gum will harden the unfired glaze.
What type of paint do you use for bubble painting?
tempera paint
Supplies needed: Dish soap, paint (we used washable tempera paint), cups, straws and paper. We used white construction paper, but watercolor paper would be especially good if you have some handy. Pretty!
