Stabilising / filling with sodium silicate
FlashGP:
I have heard you can stabilise Aust turquoise with sodium silicate. I was wondering if sodium silicate could be used to fill or harden soft patches in bolder opal to improve the shine on the polish of the matrix.
Has anyong had experience with sodium silicate
Agate Head:
try star bond thin you can find it on the net
FlashGP:
Thanks Agatehead,
I didnt realise the material superglue is made from would act as a filler and set in air.
Agate Head:
i have used it on turquoise dino bone rainbow matrix from andamooka works ok
Rusted:
I have tried a few times using Sodium Silicate without success, the recipe that you can find on the internet relies on some USA pill or tablet that is unknown in Australia to polymerise the sodium silicate, I have no idea what other options to polymerise the SS we have.
I have used super glue on boulder Opal, it does a reasonable job.
