Time delay hardener/ thickener for clay, sugar syrup, water and zinc sulphate paste.
Hi All,I have a product that is very difficult to get right, it wants to have the consistency of a thick, sticky clay to be spread on and stick to hard surfaces.
It has a very fine line between being far too sloppy (not setting at all) and setting absolutely rock solid, it also really needs to be thin and pourable when initially mixed and set to the desired consistency to allow it to be poured into pots fairly easily.
Recently I have tried Xanthan Gum and this had the desired result of hardening/ thickening as the solution cooled but the finished consistency was all together too, well... gummy! It was more keen to stick to itself than anything else.
Anyone have any bright ideas... I wondered about something along the lines of plaster of Paris. Is there anything obvious that I am missing?
Any help appreciated!
