I'll have to check (and come back later) on how much I use, can't remember at the moment.
I made up a mixture of 5 grams of Tylose to 1 pint of water - I think you could easily use more Tylose, up to10 grams without any problems.
I used hot water and a balloon whisk, it will want to clump up if you don't work fast.
This will make a gloopy sort of syrup, just add some to your glaze and stir it in.
100ml of glaze should only need about 10ml of the mixture - it's difficult to be precise without knowing how thick/thin your glaze is already
