Alternative Lake Making Process - Brazil Wood Lake

[@mrsupaconducta]

This makes me want to get some lab ware and start hunting for Brazil wood, so I can run these experiments. It looks like a blast! Thanks for the inspiration.

[@twycross3]

Wow what a color difference!! The purples and plum colors remind me of the cobalt pigments. Can't wait to see the lakes made into a paint!!

[@TheAlchemicalArts]

I will make them up into oils I think.

[@lucazsy]

I love pigmenets, your videos and I'm Brazilian. So, this video made my day. Thank you.

[@Skipperau]

Very informative. Thank you for your research.

[@thehyperscientist1961]

Good to see you're back and doing well. These colours looks very nice anyways, even though it's not the red we we're expecting

[@jeonbakson2576]

So beautiful and amzaing！

[@Lemu_with_a_shirt]

Oh I absolutely love that deep plum, very interested to see how that will look as paint. Also the others of course, that coral, despite not being a colour I'm all that fond of, intrigues me.

[@otilium7503]

Thanks!

[@PRAGMAGICK]

Beautiful.

[@AirbornMuffin]

Hallo there very informative, thanks for postings I want to set up to extract pigments from nature and do lake making can you advise where I can buy the the equipment ie funnel pump etc thank you

[@1aliveandwell]

Vinegar from market is usually 5%. Do you use pH paper to see how balanced when using the acid and alkaline solutions/substances? Very interesting. Do recall someone who knew people that carefully harvested the S.A. Brazilwood or maybe it wa Logwood. She sells naturally dyed fabrics.

I made a lake Pigment from Phernambuco wood, I used a basic solution with Sodiumcarbonate for extraction. The Brasillin goes much better in solution with a high ph.

You think it is possible to Lake Purpleheart hardwood? It has a lovely purple colour, I wonder how the Alum would affect it.

[@gavinjenkins899]

I wouldn't describe it as "Staining the chalk". As far as I understand, the chalk should be completely destroyed chemically here if you measured it out stoichiometrically, and replaced by a mixture of the same aluminum hydroxide as in the normal lake method + a whole bunch of precipitated calcium sulfate AKA gypsum that bulks out the product as a filler. Normally all those sulfate ions and (for washing soda sodium ions) get thrown out in the supernatant liquid, but this time the sulfate and (now calcium) stick around as part of your pigment, hence the vastly higher yield. Gypsum is also a hydrated mineral, (I'm assuming it's hydrated here, never calculated it carefully) so that trapped water explains even further additional yield weight. I get multiple times more weight of product when I use chalk as the alkali, but it also makes the result less tinting and much more opaque which isn't too popular for watercolors. For yellows, I think it's worth it, because it actually legitimately brightens and improves the yellowness quite a bit. And historical sources suggest it for yellows frequently too. if you use too much chalk stoichiometrically, and actual chalk ends up in your final product, it is visibly obvious, because it makes the paint SPARKLY! Which can be kind of cool if it's what you want. But annoying if it isn't. I aim for an excess of alum for this reason.

[@TheAlchemicalArts]

Thank you for this explanation. I know this is what is happening to some degree but it's nice to have someone explain it clearly. I often find my understanding of chemical processes is more simplified and intuitive than precise. You are right about the incorrect use of the term staining and I shall bring that up next time I do a lake video.

[@sophievautour8573]

Do you sometimes use calcuim acetate? From eggshells dissolved in vinegar Do you know the difference between calcium carbonate and calcium acetate?

[@vitriolopinxit]

What a beautiful set of yields! It looks like in the acidified run with sodium carbonate the alkali and the acetic acid had reacted, just as you pointed out, and the resulting sodium acetate might have buffed the pH to a milder yet alkaline environment. Maybe buffing the alkali solution beforehand might be helpful for more consistent results. By the way, an ethanol or isopropanol spray might be helpful for getting rid of the froth, as It breaks the surface tension (common practice in soapmaking). I ignore if those alcohols might react with the other materials, but it's worth a test :)

[@TheAlchemicalArts]

I will have to give the isopropanol spray a go cheers.

[@windsurfer3329]

Hey, I enjoy your vids! Can you tell us about this pigment's permanency? Thanks.

[@TheBlueWizardOfWestVirginia]

Try using an alchemical menstruum known as radical vinegar as your acid

[@sophievautour8573]

i have been tryint to lake cherry bark red, but the pigment seems to fade after the chemical process has taken place. As an ink it works quite good, but i would love to have it in a dry from

[@Polygraphice]

There's an 18th century book called Abdecker that deals with cosmetic recipes. I'd be really interested to see what their "excellent paint for the face" would look like if made! It's made from sheep's trotters and calve's feet, borax and burnt alum, nothing the average person can do but possible with the equipment you have.

[@MeredithSK]

Why does it matter if it’s hot during the filter process?

[@fromp2u]

Does anyone out there know the name/author of the book referenced and briefly shown at the beginning of the video???? Appreciate any help.

[@sophievautour8573]

how do you decide how much Alum to use? I have made a lake with alum and calcium carbonate, and it dit not froth very much. I wonder what it indicates. ..

[@SolveetCoagula]

nice stache :)

[@paranoiarpincess]

The only thing I hate more in the world than greed, is money. I actually have, for the last 5 or so years, been actively thinking as often as I can, of ways to both entirely abolish currency, and completely change the way we Interact as a society when it comes to trade and such. I thinknour current system is unjust. Laziness should not be a death sentence. Work=eat is quite unfair to those not work minded. It isnunfair to the disabled because not only do most places not have proper Healthcare (I am lucky to here in Canada, but so much isn't covered that should be) but even someone like me, fortunate to be given my livelihood by my provincial government, doesn't actually get enough money to live near the hospital that if I am not at least this close to, I could die becauae of it. For example, they break down the amount of money they give me each month, and I am alotted $900. My rent is well over $1100. It is the literal cheapest 2 bedroom apartment in the entire city, and surrounding area that we could.find at the time we moved in. It was just over $900 when we did, about 7 years ago. We have not had an increase in our rent allotment since. So the money comes out of the clothes, food, and bills. Anyway, my point is, because I can't work, we are stuck in an apartment that is too small for three people, a cat, a medium sized family of spiders, god knows how many mice, and even more cockroaches. We can't move because the hpspital I was talking about was one of two that has the only machine that can save my life if my blood disorder decides to have another episode, out of over 100 hospitals just in the megacity where I live. When I was diagnosed, my doctor was disappointed I couldn't afford to move even closer to the hospital that's how important it is. This had me realize even more than ever that having more than the majority of Canada's population living under the poverty line not only is extremely unjust, it's not sustainable. But we can't abolish currency in only one country. We would have toncome up with a global solution, you know? Anyway, I'm sorry to talk so much about this on a lake pigment making video lol, I just got so animated about how unnecessary it was for our stupid human butts to go and commit such massive and unnecessary deforestation to near extinction entirely for things like pigment and musical instruments. I agree these are important, don't get me wrong, but there is absolutely zero situation where this was the only choice. We absolutely can harvest sustainably but because of frickin human greed, jerks like them couldn't be bothered, and now we don't have access to it anymore. Grumblegrumblegrumble sorry.
