Seems to work well but a bit sludgy on a wet brush
Could do with being in a plastic container and not a poly bag which is not good in the long run

Fantastic product
I have been struggling with the new version of supposed Borax, other jewellers I know have also had problems, especially when trying to cast. I tried the product today and it works better than the old Borax. I totally recommend this product.

Ottimo prodoto
Ottimo prodoto...lo ho usato per argento e per brazatura con otone e funziona a meraviglia. Un unica cosa che ho notato e che macinato piu fino va meglio
