Which crystal dissolves in only hot water and recrystalize on cooling

AI Thread Summary
The discussion centers on finding a crystalline chemical that is soluble in hot water but not in cold water, suitable for binding glass beads. Participants suggest that while there are substances with the desired solubility characteristics, they may not effectively serve as adhesives for glass beads. Cyanoacrylate glues, commonly used in jewelry making, are recommended as a reliable adhesive for attaching glass. The original poster seeks a solution that can be injected as a hot water solution and crystallize upon cooling to bind the beads together. However, concerns are raised about whether crystallization would still leave the material mixed with water and if the binding solution needs to be water-soluble or simply solidify. The conversation emphasizes the complexity of achieving the desired outcome and the potential need for alternative adhesive solutions.

Dear all!

Somebody, please tell me which crystal is soluble in hot water but not in cold water.

I am looking for some crystalline chemicals which are strong enough to bind something like glass beads. As I mentioned, it should be highly soluble in hot water (or change into liquid on high temperature) but should not be soluble in water in normal condition of temperature and pressure.

I am afraid I might be able to find such materials (or such material in reasonable price) or not.

Thanks in advance
Peace

There are plenty of substances with solubility changing the way you describe, question is whether they will work gluing your marbles together.
 
You are probably going to have use some type of adhesive/glue.

Jewelers use cyanonacrylate glues (superglue) extensively to attach semi-precious gems to a bezel, for example. And this type of glue will attach to glass.

There are solvents/debonders for these glues - see Section 5 in the link below.

Borek and Jim thank you.

I am looking for something like Borek wrote. Could you share some idea Borek? Let me describe my problem. Say, I have a sack full of glass beads (0.5 mm). I would like to inject the chemical in the form of solution(dissolved in hot water). I want this solution to crystallize on cooling and bind the glass beads on sack. Is it possible?

Thank you once again.

Peace
 
In most cases, if it crystallizes, it will be still mixed with water. Is that what you want?

Does it have to be dissolved in water? Isn't it enough that it solidifies?

Do you want to be able to dissolve it later?

I don't have any particular substances on mind, but there are plenty of reasons that can make the result different from what you want to achieve.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
