Not fired clay, and this can even include Play-Doh or modeling clay or whatever (actually, that would be better… I need something cheap that will kind of disintegrate in a container of water).
Also, it doesn’t have to dissolve completely, just enough that there are really noticeable changes/distortions in the original form of the clay after being submerged in the water for a certain amount of time.
4 answers by real people - What types of clay dissolve in water?
Unfired earth clay (pottery/ceramic), or air dry clay will do it.
Home made flour “play dough” will do it rather quickly.
I don’t think real Play-Doh will and polymer clay which is ground up PVC plastic with a moistening solvent that bakes out will almost certainly not.
Modeling clay, which is oil and wax moistened and never hardens will not
Any type of clay will do. Whenever clay gets wet it begins to want to dissolve and turn into a slip.
the previous responders have been top-on approximately backside watering. it is very genuine for somebody who has little journey which incorporate your self. i’ve got discovered that I even have super success with the plastic “self watering” pots that are bought at mass-retailers. (which incorporate Wall-Mart) they’re inexpensive and intensely forgiving, yet once you opt for for to maintain the pot you have have been given, get an previous soup bowl for a saucer – there will be adequate intensity so as which you would be able to fill it a million/2 way. finished saucers continually seem to get bumped, sending water on your stuff you opt for for to maintain dry. (a minimum of that’s what happens to me.) you have heard approximately steadily increasing the dimensions of a plant’s pot because it grows, yet cutting-edge potting soil’s have made that much less significant. That stated, flora basically approximately continually have too small a pot and fairly respond to an more desirable length, so possibly purchase a small bag of potting mixture. it can’t be very laptop, however the mixes with controlled-launch fertilizer paintings super. despite you do, avert “funds” or “domicile” manufacturers – flora seem to comprehend while they have been taken on a inexpensive date. by way of fact it is iciness top now you probable do no longer could desire to rigidity approximately giving your plant too lots mild. placed it in a vivid, sunny place and desire for the suited. AND, if for some reason it would not make it, you would be wanting a sturdy pot and soil for attempt # 2. sturdy success! thought after examining others: whether it is a spider plant, I even have seen scarry image’s of them breaking ceramic pots. Spider plant roots do no longer look like roots – they’re extra like a mass of long, skinny fleshy arms. possibly which will help in identity.
ceramic/natural clay. I think airdry clay too. Not polymer clays like sculpey or fimo. Not oil-based clay.
Playdoh is just flour, so that would dissolve too.
Answer by ChatGPT - What types of clay dissolve in water?
Clay minerals are naturally occurring substances that have varying degrees of solubility in water. The solubility of clay in water depends on the specific type of clay mineral and its physical and chemical properties. Some types of clay dissolve in water to varying extents, while others are relatively insoluble. Here are a few common clay minerals and their solubility characteristics in water:
Kaolinite: Kaolinite is a type of clay mineral that is relatively insoluble in water. It may absorb water and swell, but it does not readily dissolve.
Illite: Illite is another clay mineral that is generally considered insoluble in water. It can absorb water and expand, but it does not dissolve significantly.
Montmorillonite (Smectite): Montmorillonite, a type of smectite clay, is more soluble in water compared to kaolinite and illite. It can undergo significant expansion when it absorbs water, and its layers may separate, making it more prone to dispersion in water.
Bentonite: Bentonite is a type of clay composed mostly of montmorillonite. It is known for its high absorbency and swelling capacity in water, making it a valuable material for various industrial and environmental applications.
Halloysite: Halloysite is a clay mineral with a tubular structure. It can absorb water and swell, but it is not highly soluble in water.
Saponite: Saponite is another smectite clay mineral that can absorb water and expand but does not readily dissolve.
It's important to note that while these clay minerals may not dissolve in water in the same way that, say, salt dissolves, they can absorb water and undergo structural changes, which can affect their properties and behavior. The extent of solubility or absorption depends on factors such as the specific mineral composition, particle size, and environmental conditions (e.g., pH, temperature) in which they are present. Clay minerals play a crucial role in various geological, industrial, and environmental processes due to their unique properties.
Answer by Google Bard - What types of clay dissolve in water?
Only water-soluble clay dissolves in water. Other types of clay, such as oil-based clay and polymer clay, do not dissolve in water.
Water-soluble clay is a type of clay that can be dissolved in water. It is made up of minerals that are easily broken down by water molecules. Water-soluble clay is often used in cosmetics, personal care products, and industrial applications.
Oil-based clay is a type of clay that does not dissolve in water. It is made up of minerals that are coated in a layer of oil. This layer of oil prevents the water molecules from breaking down the clay minerals. Oil-based clay is often used in pottery and sculpting.
Polymer clay is a type of clay that does not dissolve in water. It is made up of synthetic materials that are not affected by water. Polymer clay is often used in jewelry making and crafting.
Here is a table summarizing the solubility of different types of clay in water:
