ANDAMOOKA MATRIX ROUGH
[SAME TREATMENT APPLIES TO FAIRY OPAL]

This is a natural opal treated so it becomes black- We purchase large quanites of rough material and slab it and then treat it so you can get a idea of how it will face. There is a large amount of wastage in preparing this material. You can cut into earrings ring or pendant stones or leave as specimens but you will have to re treat if you take too much away
Mined in Andamooka Sth Australia
TREATMENT FOR ANDAMOOKA MATRIX WITH SUGAR ONLY.
MATERIALS
250 grams glucose,white castor sugar,pot or pressure cooker,plastic tweezers.
STEPS
-Pre shape the material


- Thoroughly dry the material in oven sun or hairdryer. You can also soak in aceton for 10 minutes to dry the stones out.
- Put water in pot on low temperature and add glucose and castor sugar. DO NOT BOIL.
-Place warmed stones into warm solution and cover the stone with liquid.
-leave on low temperature for 24 hours but DONT BOIL.
-Remove with tweezers and let cool.Use a paper town to wipe away access.
The next steep is to carbonize the sugar in the stone. Place the stones on a metal or pyrex dish and place in a kiln at 500 F degrees for one hour.This will burn or carbonize the sugar in the stone.
_When the stones have cooled clean on a grinding wheel.
Remember to take all precautions with gloves and mask and clothing with good ventilation.
This is a natural product so results may vary a bit due to how porous the sandstone is. Some material will have to be treated a few times to get good results. You can also experiment with various temperatures as i like to cook with lower temperatures.
Remember to have fun!
WE HAVE TAKEN THE PHOTO WITH THE ROUGH WET.
In the learning section of opal actions there is details on how to treat with acid and sugar but this sugar only gets good results if the material is porous
-

POLISHING
The surface is porous so its hard to get a good finish.
You can polish as a natural stone or coat it with resin to get a better finish.
We suggest a polymer resin as its stable.inert and nontoxic and dosent yellow..Check out our listings of fairy opal polished in sedaopals.Some of there were polished in china under vacume with a amazing finish.
We have also used mono-compontent thermo set resin,cynoacrylates and 2 parts resin but these can turn yellow over time. ive even heard of nail polished used and hardened under uv lights.
