I turned some of my Seal Slate pigment into acrylic paint! I mixed it into a matte acrylic medium and it worked so well, even when mixed with other colours. I really like this piece so far.

For those unaware, Seal Slate is made from using a waste product from cutting mosaic tiles. very kindly sent me bags and bags of this dried up material that would usually go in the bin for me to wash and process into a fine artist pigment. You would usually find it in my Cornish pigment watercolour pans. As I have it in abundance I decided to experiment!

Do you like it so far? Let me know!

Seal Slate and other colours will be going live on my website soon in cheap grab bags as they were made using my old binder recipe. Sign up to my newsletter on my website to know when they are live!

Two of these colours are not like the others 👀

Looking at my vast collection of pigments I have yet to turn into paint and stumbled across these two bright beauties 🤩 You can easily see which two they are given by how different they are from everything else!

Here we have Madder Lake and a verdigris pigment. I made it very early on in my pigment exploration.

I made the pink pigment out of madder root using the laking process, which precipitates dye in a ‘bath’ into a solid pigment. This is then dried and ground and used however you wish.

During the Renaissance, madder became a popular natural pigment for artists, contributing to the rich colour palette of the era. The vivid reds derived from madder were used in iconic works of art and were often utilized as a glaze to strengthen the vibrancy of vermillion. You can see Madder Lake being used by Vermeer in ‘Girl with a Pearl Earring. (Swipe for close-ups)

However, in the 19th century, with the isolation of key compounds from madder, synthetic alternatives like Alizarin Crimson emerged, gradually replacing the traditional use of madder in the art world.

I made the Verdigris pigment using a bit of copper piping and um…chemistry. It was in my old uni bedroom and I honestly can't remember exactly how I did it. It might still be on my feed somewhere if you scroll long enough 😂

Verdigris Ancient civilizations, including the Egyptians and Greeks, used verdigris for various artistic purposes, such as colouring statues, jewellery, and illuminated manuscripts. In the medieval and Renaissance periods, artists, it was a popular choice for achieving green tones, often seen in foliage and landscapes.

Despite its aesthetic appeal, verdigris tends to corrode over time, which can impact the longevity of artworks. Over the centuries, artists and conservators have developed techniques to stabilize and preserve verdigris pigments, allowing its historical use to be appreciated in art conservation today. You can see the corroding effects in Vermeer's painting of ‘Maid and Mistress’. Analysis has shown the fading of the once-original green tablecloth with the verdigris glaze over ultramarine blue.

Have a look though my snaps from north wales!
There’s me in the first pic. We went on the fastest zip line in the world, and extreme caving (think zip lines across caverns). I saw lots of great colours in the cave from iron, sulphur and other minerals I don’t know the name of 😬 our guide gave me some lumps of rock to take home.

Beautiful place. Will definitely return. In the mean time keep your eyes peeled for a wales palette 👀👀

The second pic are three exiting colours of slate I found. Lots of slate around as it was predominantly slate mines around.

On rock bashing business today! Make sure you wear the appropriate protection with this kinda stuff.
I’m practicing a new washing and refining technique for my pigment processing. It’s all manual and done my hand which makes Cornish Pigment a labour of love! Hope everyone’s having a nice time coming up to Christmas🎄

Exploring Perranuthnoe, or more importantly Trebarvah Mine. A friend told me that with a bit of hunting you could find exposed copper ore just along the beach. Unfortunately we didn’t find any but I will certainly return soon.

Trebarvah Mine, apparently also known under the name Wheal Castle, lies to the east of Perranuthnoe village.

This entrance or adit can be found on the beach. I wonder if there’s a different entrance?

I collected some of the dirt from the entrance to be turned into pigment and also collected some interesting looking rocks from the beach. Still hoping to find copper here one day!

The mine was predominantly a copper producer, with only a small quantity of tin being raised. There are records of 1730 tons of brown hematite produced around 1873-4. Some lead and zinc is also recorded.
