Tips: The moms wanted to stir this like a batter, but that whips too much air in it. Stir in a circle with less up down so less air gets stuck as it thickens. Tap hard before hand goes in to let bubbles rise to top. If you want a smooth base for your hand, smooth the top of the alginate before it dries with bubbles. Fill mold with half the amount of plaster it needs, roll & tap well to remove bubbles, then fill to top mark.
The mix is 1:1 by volume. The alginate powder completely dissolves similar to salt or sugar in the water. This means when you're trying to figure out how much you need, think about the water volume as being very close to your final volume when mixed.
I see several reviews saying the product is crap and others saying do not buy it. All I can say is that your doing it WRONG! If you use warm water, you already screwed up. The water at 80 degrees actually feels slightly cold to the touch. The warmer the water, the faster it sets up. 50/50 mixing ratio is a bit off for my liking but that's my opinion. I like to add an extra ounce or so of water to thin it down a bit which produces excellent details and pouring ability. Ive done several molds from this package including hands, feet and a face and still have some left over to play with.
The trick is to find a water proof container just slightly larger than what your casting so you use less product.
I use old lures melted down in an old microwave for my lures. This product hold up very well. If you cast a larger piece, you will see steaming and bubbling of the melted lures but in the end, when its cool, you still get excellent results and very few bubbles.
Please, do not be put off by the negative reviews. Not every one can read and comprehend the instructions. Some people do not even try something small to see how the product works before trying the actual project. Ive yet to screw up one single project.
I know the ideal mixing apparatus is one of the fancy mixing heads that you use with a drill, but I was able to mix it by hand and get great results.
