Hello everyone,

I’ve recently started setting stones and need some setters pitch ( I tried it out in a class) im trying to buy some online - cooksons doesn’t seem to sell anything, amazon sell something called polymorph, it’s approx £10 with delivery for 500g. Is this the same as thermo-loc? Should I save my pennies for the right stuff - if so does anyone have an idea where to get it? I’ve indulged in a few nice stones so I would like to buy something that is up to the job.
Many thanks.
