The instructions that come with this alginate are not that great. They tell you to measure your powder by volume and then add the same volume of water. I personally find it easier to weigh the powder in grams and then add 3 times the amount of water in a large mixing bowl. So 100g of alginate powder requires 300g (or 300ml) of water.The instructions will also tell you to use water that is 30°C, which will cause your alginate to set insanely fast. Probably faster then you can even mix it and work with it. So it is perfectly OK to use cold tap water, which will slow down the curing process by a couple of minutes. Those extra minutes can be the difference of being ready in time for the cure or not.The white powder will turn bright pink as soon as you add the water (and smells minty too) after which you must mix like crazy until the powder is blended smooth with the water. You will benefit from a had mixer to do this fast enough and without lumps, so have it to hand before you start the process. Clean up requires scraping the alginate from the mixing blades after it has cured.Pour the mix into your form and cast the object immediately. The mix will turn from bright pink back to white as it firms up before your eyes. As soon as the alginate feels firm you can gently release the object and then cast immediately. Alginate starts to degrade rapidly from the moment it has cured, and will start to 'sweat' as it releases the water, so it's really not something you can prepare in advance. Alginate also traps air bubbles so rarely produces flawless casts. Be prepared for bubble defects on the surface of your castings.I have tried a few different brands of alginate and find them all to be more or less the same.

Having followed the guidance, waiting to dry with the mix suggested seemed to take ages, the alginate seemed to stay pink for the longest time, and even when discarded and returned to days later, there was still a lot of undried pink throughout the majority of the mixture.Was still able to attain a decent casting of the objects, but will maybe try another one in the future.

The item was exactly what I needed. The alginate material performed flawlessly, perfectly capturing the intricate details of my daughter's tiny foot. The preparation process was a breeze, and the provided instructions were incredibly clear and straightforward. This product made the task not only convenient but also yielded fantastic results, preserving a precious memory with remarkable precision.

I used this to create a mould of my baby’s feet and it set in 2 minutes. Great at capturing fine details, as long as my baby can stay still in one minute. Worked well with stonecast. Happy with this!
