LAKE PIGMENT (COCHINEAL)- NEXT STEPS

                      Cochineal Pigment
                        - the next steps.

Its the next day:

I couldn't see any pigment at bottom with clearer fluut top which I was expecting. I filtered one of the jars of dye stuff to see. 


Yay some pigment. A very deep colour atm. But not as much pigment as I expect. I will let it dry then mull it before I wash it. This is normally done before it is filtered but as I couldn't see any pigment at bottom so it wasnt an option.


I decided to experiment with the left over cochineal by reheating and adding extra alum and soda which I mixed in hot water. Very pleased that I got more fizz. 

Interesting that one of the dye baths changed to a more pink colour. Unfortunately I didn't keep records of how much of the alum or soda I used.

I decided to filter one lot without letting it settle to see what difference, if any, it would make.

Filtering through 2 coffee filters, I noticed that the liquid was completely clear which is unusual. That didnt happen on the first filtering? 


There is more pigment. 


I filtered some of the pinker solution to see if the water would  come out clear also but surprisingly it didn't? 

I let the other lots settle naturally and am pleased to see the  pigment and separated fluid.
I used turkey baster to remove the clearer water and refilled with water for another wash.
I will do this several times until the top water is clear.
Then I will filter it through coffee filter to get the precipitated pigment.
After that I will let it dry. Then grind it in a mortar and pestle. Followed by lightest testing.
More on how it goes in my next post....

Keto 50kg weight loss and brief history

Image
Thought I would post a little history. I used to be martial arts instructor (South Pacific Tae Kwon do, Rhee Tae Kwon do) and right into exercise and healthy lifestyle so it was devastating to me when I got diagnosed with a couple of auto immune diseases causing great pain followed by massive weight gain. This also affected my mental health greatly. My MH has been an ongoing issue since childhood following many things that children shouldn't have to deal with but that I am not going to talk about here. PTSD, depression, anxiety, bi-polor syndrome,aggrophobia etc. All the labels. With the pain and my worsening MH, I ended up in a very bad way. Culminating in basically not leaving my bedroom for 3yrs except for dr and hospital visits. Follows by an extended stay in an acute mental health ward getting 11 ECTs (electric shock therapy). Not fun. But to make it brief, I started to recover, found out that I am an artist and started a not for profit group (Demented Artists Group I...

GUM ARABIC. A brief history.

Image
              GUM ARABIC HISTORY         By Lady Symonne de la Croix                            26.3.20 Gum arabic, also called acacia gum, is made from the sap of the Acacia senegal tree, or gum acacia. The sap is a cold water soluble polysaccharide. In its gum form, it thins out as temperature rises. During the stone age, it was used as a food and an adhesive. Japanese and Chinese used acacia gum for painting as early 4000 B.C. Other documented usages have shown that in Ancient Egypt (around 2650 B.C) it was used in the preparationof inks, paints and dyes. It was the pigment binder for paints used to make hierglyphs and ancient inscriptions refer to it as "kami". Gum arabic was used in the mummification process to adhere the bandage wrappings. It is known that Cleopatra ordered recipes prepared with acacia gum for her favourite lipstick. Ancient Gr...

Manuscript Inspiration for 12th night Winning Entry

T'OROS ROSLIN GOSPELS Inspiration Manuscript By Lady Symonne de la Croix 27.1.20  Recently I posted of my Kingdom A&S win at 12th night in Mordonvale. Someone suggested I put up a couple of blogs about it so here goes. I wanted to try egg tempera on a rabbitskin glue gessoed box.  And I was looking for a way to incomparate it to fit with the Kingdom competition. I decided to use a Russian manuscript  (to fit the theme: Eastern Europe.  It is a beautiful and intricate image that I broke in pieces (not literally) and put on different parts of the box (front,top and sides). I found it interesting that the manuscript was still being used as a model book, 500yrs after its creation. Here is part of the information that I included in my documentation about the manuscript. T'OROS ROSLIN GOSPELS  This manuscript was made in 1262 by an extremely prominent illuminator, T'oros Roslin (Armenian, active 1256-1268),who extended...
