Having just picked up an ultrasonic humidifier, I wanted to make some cold-process colloidal silver. My glucose made from corn syrup had gone bad & since we don't use much corn syrup (and it seems to have disappeared from the cabinet), I decided to try to make some invert sugar.
My first surprise in following the recipe at
http://www.cgcsforum.org/index.php?topic=674.msg3556#msg3556 was when I added 50g of sugar to 50ml of water and ended up with 80ml of solution. That puzzled me as I thought I would have to add water to get to 60ml at the end.
I tried heating it in the microwave, which boiled off enough to get to 60ml, but I don't think the temperature ever reached 227.
What am I missing? Does it need to be boiled down on a stove (or hot plate)? When I looked at examples on the Internet, it looked thick. Does it need to be diluted like Karo?
Thanks
