IS COCHINEAL COLOURFAST?


            COCHINEAL COULOURFAST TEST                        By Lady Symonne de la Croix
                                  25.3.20

               
     

I removed the tape from the original Cochineal Lake pigment colourfast test after 1.5mths. (7.2.20 - 23.3.20)
{Note: bottom 2 are dragons blood.



There mostly appears to be no fading except for the first one. Unless my eyes are playing tricks on me.


           Dyeing on Linen

As a side experiment I attempted dying to dye some linen strips as a colourfast test.

The left side is straight cochineal and the right side is cochineal and alum {before laking).
I haven't done any research into dying material so could definitely have done it incorrectly. Mine was more of a dip it in and see what happens kind of thing 😉




I notice that there is no fading in the straight cochineal but definitely fading in the alum one. I thought that would be opposite hmmm.

Interesting that there is definate fading in material but not not really in the pigment on paper.
Maybe the laking process?

I will check again in a few months. But I am tentatively happy that I have a viable pigment.....

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.

              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...
