I've just looked in the boot of my car and discovered a 25Kg sack of pure Sodium Metasilicate Anhydrous ![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I've been using the Sodium Metasilicate developer crystals for developing photo boards for a number of years but have always bought them in small packets of 50g each (diluted with .5 to .75L of hot water).
I understand the stuff sold in the small packets is Sodium Metasilicate Pentahydrate but does anyone know if the straight Sodium Metasillicate (not Pentahydrate) is any good for developing before I crack open this large sack ?
Typically I'd bought 10 packs of 50g developing crystals at around £1 each before I "discovered" this sack of stuff on my journeys![Stick Out Tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
