  • FAQ
    Q1. I can only get small crystals to grow?

    A1. A Maybe the water is dirty or the dish is dusty! Also our experts say PLEASE don't disturb the dish or swirl it about to see what is happening. Leave it totally still in a dust free place to cool naturally, and then evaporate. Tip the saturated solutions in very very gently.

    Q2. Cannot seem to form any crystals at all, just seem to be left with a sludge of chemical.

    A2. If the water is dusty or slightly dirty, the crystals form on every particle present in the liquid. So they tend to make a slush of tiny crystals.
    1. Wash the dish out in tap water first but don't dry it with a towel That will leave particles. So:
    2. Keep the dish in a very clean place with no dust falling on it as the crystals form.
    3. And if that doesn't work, use filtered water. Your water supply may have particles in it.
    IF THAT DOESNT WORK use slow crystallization by evaporation. This means not using a saturated solution, but a slightly weaker one. (The plastic rock does not need to float up). But the dish must be kept in a very dust free and dry place. We find that hot saturated solutions sometimes tend to crystallize indiscriminately and fast, but a slower approach via natural evaporation will select the first formed crystals to be the seeds for further growth even using the same water and same conditions. But we are not sure why! Sorry - its a mystery but it seems to work.

    Q3. More crystal growing cards?

    A3. Sorry, we are not abel to sell the card separately. Most commonly available card types just do not work! But these will work
    1. heavy grade filter paper - from lab supplies
    2. Chromatography card; heavy grade - from lab supplies ( this is best we think)
    3. Blotting paper if you can still get it, but it tends to lose strength as it gets wet.

    Q4. Where do I get largish crystals? What are Magic Rocks for?

    A4. You need to find a couple of larger crystals in the Monoammonium Phosphate chemical jar. They are all small - just see if you can find larger ones amongst them. In fact any individual crystals will get the seeding process happening, but it is nice to see clearly where the growth will start from. The magic base rocks, if scratched to provide nucleation surfaces, will seed out a cascade of crystals in a saturated solution. But to make individual or a few larger crystals we start with seed crystals.

    Q5. No crystals growing!

    A5. Crystallization rate depends largely on temperature and humidity in the home, no matter what we specify in the booklets. Temperature and humidity play a great part in the speed of crystal formation. Crystals form - but slowly and usually they are bigger. But it may take a week or more. We suggest re saturating your liquids with more chemical in very hot solution. Hotter than hand warm - which is the safe temperature for children. So try putting the bottle in a bath of newly boiled water, until more dissolves. Carefully decant the very hot saturated liquid into the well. Let the saturated liquid to cool in a dust free place. You will get crystals growing as it cools, unless the laws of solubility and temperature are broken. Then as the liquid evaporates the crystals will enlarge. Dusty air or impure water can also lead to extraneous nucleation points leading to cascades of smaller crystals. So clean water and clean air for best results.

    Q6. Monoammonium Phosphate was hard in bottle!

    A6. Monoammonium Phosphate does sometimes solidify in storage, please shake or poke with a spoon to break it up. Even bang the side of the jar with a hammer! If it”¦s still solid, please contact us directly.

    Q7. Why is my yellow dye cloudy lumpy and/or solid?

    A7. This sometimes happens to the yellow coloured dye when it gets too cold. Just shake it and warm it up in your hands, or keep it in a warmer place.

    Q8. Crystals didn't grow on my Magic Rock. What's wrong?

    A8. Roughen the rock with the sand paper until it is really scratched up well. Also, extra hints from our lab scientists: wash the rock before dunking it in the saturated chemical. Plastic dust causes lots of small crystals to grow - but but on the rock. We grew HUGE rock crystals by replacing the liquid two or three times.

    Q9. What I can use to remove 'crystal liquid stains' from a carpet?

    A9. Sorry to hear you have 'crystallised your carpet'.

    The base chemical is ammonium monophosphate which is itself colourless and harmless. ( It is also an agricultural fertilizer.)

    1 If it is this alone that you have spilled, just use a sponge in cold or room temp water to repeatedly and alternately to soak, dissolve and then re-absorb the chemical in the wrung out sponge. Try not to let the patch spread out too far.

    2 If the weather is very dry, you could also wait until it has dried out totally and you have white powdery crystals showing up, then vacuum thoroughly. If you have a beater-head on the cleaner, all the better. Then, just to finish off, try the sponge treatment too.

    3 If you have spilled the chemical with the (food) colourant in it, best start with strategy 2. After vacuuming then use a carpet stain remover liquid and sponge on and off. That should do it. If some stain still remains, use ”„Napisan”¦ or another non-chlorine based clothes stain remover.

    4 If some stain still remains - sorry, you just have to wait. The colourant is food grade and biodegradable and will loose colour with time and wear.

    Q10. How can I really saturate my solutions?

    A10. The hotter your water bath, the more saturated you can make the the solution. DONT USE BOILING WATER AND DONT BURN YOURSELF! Hot water from the hot tap is just right, but you may need to change it a few times as you dissolve the crystals. 4 spoons of monophosphate should totally dissolve in 50ml of water depending on temperature. And 5 spoons will be just too much - and that is ideal. Let the undissolved crystals settle, and decant the solution into the super clean dust free dish. And let the saturated solution cooool SLOOOWLY.

    Don't put it in a cold water bath! If you do you will get squillions of tiny crystals rushing out of solution. If this happens, dont throw them away, just reheat and they will dissolve again.

    Q11. Squeeze out the solution into the tank but there is no coral?

    A11. You need to fill your tank with the sodium silicate solution exactly as on page 11. Then you add the magnesium sulfate solutions to it. We think you just have started with a new tank of plain water on page 12! You need to use a sodium silicate tank from page 11. Or there is no Magnesium Sulfate salt dissolved in the coloured solution, or it”¦s too diluted!

    Q12. More Sodium Silicate solution?

    A12. Sodium Silicate solution is used in large quantities in the paper and cement manufacturing trades but public access is very difficult these days. The old common name is 'waterglass' and was used for home preservation of eggs. The problem is that there are many variants which can be very dark in colour, very caustic, widely varying in density and quite dangerous. Our variant is specifically sourced for its density, clarity, and is the safest and lowest alkalinity available. Sorry , we can't help with a public source. Do beware of very caustic solutions.

    Q13. Seahourse/Skull doesn”¦t float in the middle of tank?

    A13. You might have broken boundary of the density layers, try squeeze denser Sodium Silicate solution at the bottom carefully, see if it starts to float. Or you have to start over the steps of ”„training”¦ again, and pour the solution very smoothly and slowly, use the spoon and lean it against the wall of tank.

    Q14. What is a Saturated Solution?

    A14. A If you dissolve lots of small crystals in water until no more will dissolve, you have made a SATURATED solution.
    The hotter the water, the more chemical crystals you can dissolve before it gets saturated.
    The solution is usually a lot denser ( or heavier) than plain water, so our Magic Rocks ( in some kits only) will float when the solution is saturated. It is one scientific way of knowing if a liquid is plain water or has dissolved chemical in it.
    Then as the solution cools or dries out, the water just can't hold that much chemical in solution. So crystals start to form. And they are usually a LOT bigger than the ones you put in.

    Q15. How to dispose the seahorse crystals?

    A15. Now, if you need to dispose of the used stuff, you can gently tip the used sodium silicate solution down the sink and flush it with water. But don't put unused magnesium sulfate solid or liquid down the sink at the same time as guess what - it'll make 'coral' in your drainpipes. But you knew that already ;) When you've tipped out the liquid - if you do it carefully - the old corals will still be standing up, especially if you grew them from 'seed crystals'. You can just scrape them into the garbage. OR more fun, you can leave them to dry in the tank. They'll last for ages and just go a spooky grey colour in the end. OR you can refill the tank gently with cold water and they will also last for quite a long time. But the colour does gradually disappear. If you have unused sodium silicate and unused epsom salts - yes, you can do more experiments but you wont be able to do the seahorse trick, unless you are lucky. Or you can put the used stuff in the garbage - safer than blocking your pipes. Have Fun from the Team at WILD! Science.

    Q16. None of my Crystal Oasis activities worked. What is Wrong?

    A16. Maybe you confused the two jars of chemicals! Magnesium Sulfate is ONLY for making gel corals. Monammonium Phosphate is only for crystal growing. Our chemicals don't get old and stop working. They last for years and years. But they might get solid in the jar. So just break them up with a small spoon.
