ANDAMOOKA MATRIX ROUGH


This is a natural untreated andamooka rough that has been sliced. This is old material that that was sliced but kept in a large collection for many years.The collection had untreated and treated stones. You can have the fun treating it. Some times you might have to treat a few times and you might like to try oil instead of sugar as listed below.

This material takes a good natural polish.
You can reshaped it or cut into smaller stones.

Remember all rough is a bit of a gamble as some will treat better than you think while others worse-! The only way to make sure is to treat it.
Mined in Andamooka South Australia


TREATMENT FOR ANDAMOOKA MATRIX WITH SUGAR ONLY.
MATERIALS
250 grams glucose,white castor sugar,pot or pressure cooker,plastic tweezers.
STEPS
-Preshape the material

- Thoroughly dry the material in oven sun or hairdryer. You can also soak in acetone 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 DO NOT 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 on porous materiel
This material is very solid

seda rough opals
seda rough opals
SEDA ROUGH OPALS is run by Paul Sedawie of Seda Opals. 8 opals can be combined in the one shipping if bought with in 7 days. The Seda Opal company was incorporated in 1994.The owner Paul sedawie is the current president of the OPAL ASSOCIATION INC. Seda Opals is an abbreviation from our surname Sedawie. The business is mainly wholesale and it is through this site that we can bring the opal fields and the bargins direct to you. Paul Sedawie started mining at the Four mile field in Lightning Ridge in 1986 with his first partner Bob Young. It took them 6 months to find a decent stone and this experience gave me a healthy respect for the stone and how hard it is to find. Previous to mining opal, Paul ran a successful mail order business in plants for 7 years which gave him a lot of experience servicing customers through parcel post. We use mainly Australia post as it has a excellent reputation for delivery to most parts of the world. I don't do any active mining now but my eldest son Peter Sedawie has taken over. This leaves me free to travel to any opal field and to enjoy the beauty of this magnificent stone. We hope you enjoy our stock and good luck with your biding.

Waarom overbieden gebruikers zichzelf?

Wanneer er wordt geboden, is dit het maximale bedrag dat een gebruiker bereid is te bieden op het product. Ons systeem zal dan automatisch namens die gebruiker bieden, waarbij het bod stapsgewijs wordt verhoogd om hun positie als hoogste bieder te behouden, tot aan het opgegeven maximum.

Als er een pictogram is dat 'Automatisch bieden' aangeeft, betekent dit dat ons systeem actief biedingen plaatst voor de gebruiker op basis van hun maximumbod. Dit kan lijken alsof gebruikers zichzelf overbieden, maar het is gewoon het gevolg van het feit dat het systeem het bod bijwerkt om de maximumlimiet van de gebruiker weer te geven.

Audit

Met het Opal Sheriff- programma kunnen onze leden een audit aanvragen voor elk product, die wordt uitgevoerd door een onafhankelijke Gemologist die de juistheid van de artikelbeschrijving en afbeeldingen beoordeelt.
