great video , i noticed you used drain cleaner what acid concentration is in that? i see people using that and most recommend 98% sulphuric acid . Will that affect the treatment like the pure acid make it darker? thank you
Perhaps it also comes from the carbonisation of textiles. Where the unwanted by-products are dissolved out to improve the quality. Maybe also with concrete, Matrix Opal. Maybe they tried to increase the opal surface by removing the by-products, sand etc. Cheers Pasci
great info for people here in Australia i treat opal and cut as well set into pendants etc go into the fields we use sugar and water, and 98% sulphuric acid need proper face breathing mask and be very careful with the acid, its safe there ha ha only snakes and spiders, no one tells you there last name at the ridge is because more millionaires there than any one knows, and Grawin to good place to dig opal

There are alot of diferent types of opal in many different stones that come from Andamooka, quartzite, Agate honey opal and many more opal stones.
