We are casting masters using the amazing casting resin and for the most part it is working out OK.
Even though we are weighing exact 1:1 for our mix, we still find the cured white to be a bit flexible and bendy.
If we increase the hardener by a tiny amount can we make the cure stiffer?
BTW, Which bottle of the product is the hardener? The clear bottle or the yellowish bottle?
Thanks for your help,

.... if the resin is still flexible after a proper curing time , you need to take a look at your mix ratio. Resin is very unforgiving...if your off even a few grams it can have undesired effects on the resin...especially the smaller the pour. Increasing the harder (catalyst) will only make a bad situation even worse....the catalyst will be the clear bottle. Be sure and shake BOTH the resin and catalyst before mixing...a couple minutes for both parts ("A" & "B") will work. Be sure and fallow the mixing instructions, especially the time duration. To help insure a proper mix ratio, I pour the catalyst into the cup that I weighed the resin in and then mix since the catalyst is a thinner viscosity than the resin and is less apt to stick to the side of the cup like resin would.

Also Amazing Casting Resin is a by weight or by volume resin - if weight isn't working right for you, try backing it up with a volume measurement and see if the ratio is off. And like Brian said, making sure both sides are shaken up before mixing is a very good thing to do as parts of each can settle to the bottom and need remixing before measuring. My rule of thumb is if I haven't used it in 24 hours, then I make sure to mix each side up thoroughly before measuring. Another thing to look at is your working environment, was it a little cool before and after when you mixed the resin? A warmer environment will speed up a cure while a cooler one will slow it down. Also if you're using a mold, warm up the mold first will help the resin cure right.
