the latest in a long line of D&D characters ! ! ! please meet outis, my archaic warforged paladin ! ! ! they were originally built to find patterns in chaos and help guide travelers through hazardous places where rules are few and far between, though a recent expedition gone awry seems to have put an end to its career

even still, they're still on a journey to some place far, far away, though no one seems to know where—least of all outis w

oh THIS is probably what happens with copper too i’m guessing, as per my long question i wrote you that you are under no obligation to answer, i got a bit overexcited and didn’t realize you’d probably receive a lot more (’:

i LOVE flame painting copper and wish i was better at it, the best artists have the time for each color down to muscle memory since it’s a delayed reaction, you take the torch off it and then the color appears properly. my problem is that copper oxidizes so fast that the colors dull or change quickly and since the color itself is an oxide that’s so thin, even pouring resin over it would destroy the effect!

but i have heard good things about and met an artist who used renaissance wax; she also sold anodized titanium and her stuff was gorgeous, it looked freshly painted! so that’s a possible solution that i haven’t tried yet because that wax isn’t cheap lol

in case we’re sharing i also want to bring up my favorite optical phenomenon, which is high pleochroism in gemstones! so far i know of 3 in which it tends to be fairly obvious:

alexandrite, which shifts all the way from magenta to green with shades of purple and blue in between

tanzanite, deep blue to lilac

Oregon sunstone, and please watch this video just for the music lmao. not all specimens exhibit pleochroism, which in this case is caused by inclusions of my beloved copper, which is sometimes too large and dense to create the cloudy nebula-like color you see in gem-quality stones. i wouldn’t be as impressed with these except i’ve seen them in person and the transition from yellow to green, red/pink to orange, and even peach to green is STUNNING 

and now i’ll stop before i go on a tangent about feldspar hahaha

You said ask metal questions so here goes: Why do knives permanently change color when u stick them in a candle?

Ah my friend, you have activated my trap card

And by trap card I mean another special interest of mine

The discoloration you see here comes from my favorite optical phenomenon (we all have one, right?), thin-film interference. The Wikipedia article linked in the last sentence does a good job explaining it, but I’m gonna do it here anyway because infodumping is my M.O.

When white light (all colors mixed) strikes a reflective surface that has a thin transparent layer on top of it, the incoming light gets split—some of it reflects off of the top of the thin layer, and some passes through the layer and reflects off of the base surface, passes back through the layer and then back out.

(Image from Wikipedia)

This means that the light that went through the thin layer and back out traveled a slightly longer distance than the light that bounced off the top of the thin layer. That extra distance means that the peaks and valleys of the light waves are now shifted off from each other. This shift results in constructive interference (peaks lining up with peaks, valleys lining up with valleys, causing them to reinforce each other) for some wavelengths (colors) and destructive interference (peaks lining up with valleys, causing them to cancel out) in others.

(Image from Wikipedia)

So now instead of getting white light (all colors mixed, no distinct color), you get only certain colors of light, and those colors are controlled by the thickness of the film. This is because the thickness affects the extra distance the light passing through and back has to travel, and thus how much shift there is, and thus which wavelengths get enhanced and which ones get canceled.

On metals that discolor in this way, the thin film is a layer of metal oxide (formed by heating the metal with a candle, torch, etc) that’s thin enough for light to pass through it. The reason the colors stop after blue on steel/iron is that the thickness required for that blue is the thickest the film can be without becoming opaque—any further growth of this layer and light can’t pass through anymore, ending the phenomenon.

So! The colors you see on heat-tinted metal are the same as the ones on a soap bubble, oil on a wet road, and many other things. The reason these objects have a spectrum of colors is because the thin-film thickness is varying—in the video above I heated one end more than the other, making a thicker oxide layer at the hot side.

Because visible light has wavelengths on the order of 100’s of nanometers, it doesn’t take a huge change in thickness (10’s of nanometers) to get different colors, which is why on a soap bubble or oil film, the colors go nuts

Finally (I promise), this same phenomenon of thin-film interference is where titanium can get all of its wild colors. The metal can get anodized, which is applying an electric voltage to the piece to deliberately grow an oxide layer on the surface—the voltage applied controls the thickness of the layer, which in turn creates the colors.

Who Are The Power Of Nutrition?

As an individual detected with CLL (chronic lymphocytic leukemia) given that 2001, I have actually had my eyes educated on Google Alerts and online as a whole, routinely seeking developments, both traditionally and in the alternative medicine arena. With the new financing, the business will certainly supply diets tailored to a 30-day nutritional reset that will certainly identify foods that have a negative influence on yearnings, swelling, digestion and also metabolism;" MedStar Healthy meals that are 350 to 600 calories, consist of 30 to 60 grams of carbs and also less than 750 milligrams of salt without any more than 7 grams of saturated fat (the diet regimen was based upon standards from the American Diabetes Organization and also the American Heart Association); a Mediterranean diet plan, designed by celebrity dietician Ashley Koff RD; and also diet regimens for new and also expecting mommies as well as macronutrient meals are additionally available. Goldberg MF, Dhaliwal RS, Olk RJ. Indocyanine environment-friendly angiography patterns of areas of loved one decreased choroidal blood circulation in patients with exudative age-related macular degeneration. Currently, Prof Longo is currently creating a clear-cut overview of FMD, and also a business he developed called L Nutra will create a five-day nutrition pack, containing bars, drinks and soups, called ProLon (costing about ₤ 150, and offered in the UK in the fall). However Mr Nash, who studies at the Bristol Institute of Modern Songs, claims he is healthier than ever before and has no plans to alter his banana intake. Also, upside down stances, such as head-stands, can enhance IOP substantially, getting to levels over 30 mm Hg in normals as well as greater in those with glaucoma. Just recently, however, it was discovered that vitamin D might have a result on several various other systems, consisting of the cardiovascular, muscle, endocrine and anxious. Whether you're seeking to count calories or simply obtain a far better understanding of nourishment, these 5 applications make monitoring your everyday consumption simple as well as-- risk we state it-- fun. With the Lean Me application, you'll have the ability to track the macronutrient values for all the food you consume throughout the day. Aiming to the side (lateral stare) temporarily enhances IOP by around 2 or 3 mm Hg. Extra regular eye motions into side gaze could function to pump liquid out of the eye more efficiently, much like the pumping of lymph with basic body language, leading to a lasting reduction in IOP. Just like MapMyFitness, Endomondo and also MyFitnessPal have developed track records of unequaled equity, knowledge and also interest in the fitness and nutrition room, as well as they are ideal companions to enable Under Armour to provide data-driven, proactive options to help athletes of all degrees lead much healthier and also a lot more active lifestyles," he kept in mind. If you beloved this post and you would like to receive far more info regarding http://mocdvehiljade.info/ kindly go to our own internet site. Approximately 50 mg/day of Zinc supplementation has actually been advised however extended use degrees over 25 mg ought to generally be come with by copper supplementation to stop copper deficiency which can enhance LDL cholesterol. Lately, the Copenhagen Agreement, a group of leading economists, consisting of four Nobel Laureates, found that fighting malnutrition ought to be the leading priority for those seeking to improve global welfare. Scientist led by Leifert in 2014 discovered that organic crops and also the foods prepared from them were up to 60% in essential anti-oxidants, and lower in degrees of the harmful metal cadmium, than conventionally created crops. One more study taking a look at the wellness and nourishment literacy condition of locals of the lower Mississippi Delta found that 52 percent of participants had a high probability of limited proficiency abilities. In the last 3 years, we have actually spent ₤ 15 million in reformulation tasks to minimize sugar and also calorie material and offer consumers better choice," stated Jon Woods, basic manager for Coke in the UK and Ireland. In one research at the university of Virginia, resveratrol - located in grape skins, mulberries, raspberries, and peanuts - literally deprived cancer cells by disrupting a healthy protein called nuclear factor-kappa B, that aids food them. As a currently hugely prominent site, it was not a surprise that Fitocracy immediately became one of one of the most preferred workout apps on the marketplace when it launched on iphone in 2012. In 2013, German bread scientists discovered that leaving bread bent on increase much longer in order to produce larger, much more program air pockets actually permitted the preference of the salt ahead through faster than in more thick breads. When it comes to exactly what is following, while Meltwater plans to keep Algo's consumer-facing apps operational, and also possibly even market its service a little bit, it's likewise counting on constructing its capabilities right into Meltwater's B2B service. Particularly, the usage of entire plant foods reduces food digestion and also offers higher amounts, as well as an extra favourable balance, of necessary nutrients per Calorie, causing much better administration of cell growth, upkeep, as well as mitosis (cell division), as well as far better guideline of appetite as well as blood sugar. That's why it deals with the apps as well as tech individuals are already making use of. It is needed for several crucial functions like law of body temperature level, absorption of nutrients, and also elimination of waste products from the body. Foods that are good resources of healthy protein and carbs include fish, poultry, meat, cheese, milk, vegetables or beans. Watch for an enhanced concentrate on information safety as information relocations from applications to the exam room. It is currently identified that most common illnesses are closely associated with nutrition and also occur from absence of minerals and vitamins, equally as some even more major disorders, which where leading in the old days, such as scurvy, noises, anaemia, pellagra, nerve, as well as beri-beri problem are just as deficiency conditions, as well as reply to suitable vitamin therapy.
