Opal is a hydrated amorphous form of silica (SiO2-nH2O); its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals.

Is inhaling hydrated silica safe for autoimmune conditions such as scleroderma and MS?

Hi, I'd like to double check if there is something safe about breathing hydrated silica vs. silica for people suffering from autoimmune conditions. My job requires us to limit crystalline silica exposure, so I am not used to hearing silica inhalation is not ok. Then I read my wife's dry shampoo and it contains hydrated silica. She sprays a ton of this stuff creating a cloud of whatever. I understand that hydrated silica is amorphous silica, and is somewhat different, am concerned because she has an autoimmune condition that research suggests is aggravated by silica (not sure what form) in the research. Does anyone know if this hydrated silica is safe for inhalation by people with autoimmune such as scleroderma or MS?

Hydrated Silica vs Fiberglass

Hello,

I'm on the search for a queen mattress for my new place and have been using sleeplikethedead but find it difficult to find information on fire retardants used. I'm trying to figure out what the safest material is in terms of health. Yes I know in most cases fiberglass doesn't matter if you keep the cover closed but I'd rather be safe than sorry.

I'm leaning towards the Love & Sleep and they have this bit on use of Hydrated Silica instead of "chemicals". Then I found some blogs on Hydrated Silica but they all seem illegitimate or funded by other mattress companies.

Anyone have any personal insight on this topic?

Where does all the hydrated silica in a toothpaste go when you brush your teeth?

Assuming you don't rinse after because there will always be some left behind... Does it eventually dissolve in the mouth, gets ingested with saliva/food/etc, or just sits in oral tissues forever? Like... isn't that kinda bad or am I nuts?

Cuz I just switched from Parodontax to Blend-a-med with stabilized SnF to complement Ultradex Recalcifying mouthwash with nano-hydroxyapatite and chlorine dioxide and girls are hot and such...

Is Hydrated Silica considered a gentler exfoliant than walnut shell?

Hi everyone! I don't see anything in a search or in the FAQ about products that use hydrated silica. I'm interested in whether this is a skin-ripper like walnut shell and salt or if it is a gentler exfoliant. I stopped using St. Ive's Apricot Scrub after reading through this subreddit and am looking for a replacement. I like to use the scrubs on my legs and upper arms for keeping bumps away, but also on my face :)

Thanks in advance for any replies!

Just finished listening to the latest Mr. Grow It podcast # 46 with Dr. Bruce Bugbee. Lots of bro-science talk that was super informative

Hey everyone!

I just finished the above podcast episode and I thought it was so good that I wanted to share it! They discuss synthetic vs organic nutrients, lighting spectrums, soil vs hydroponic, flushing, silica use, and more. Remember that Dr Bugbee works at the University of Utah conducting research on medicinal hemp and other plants and while some of what he says may go against traditional practices he knows what he’s talking about.

The most interesting points Dr Bugbee made were:

  • synthetic and organic nutes end up being the same base chemicals once the plant takes them up. Organic nutrients have been thought to increase terpene content for a long time, but what Dr Bugbee has found is that organic nutrient use may stress the plant ever so slightly so that terpene expression is increased. I guess synthetic nutrients can be immediately absorbed by the roots so there is less stress on the plant while it waits for the microbes to break down the organic components?
  • Synthetic nutes do not kill the soil microbes but in high concentrations can alter the diversity of the micro biome to favor salt loving microbes *large scale use of organic nutrients can result in phosphorous pollution. This can be avoided by using synthetic nutes in the correct quantities which reduces how much excess nutrients ends up in water and land
  • Blue light can cause more compact plants with fender buds. Far red light increases photosynthesis but creates taller plants with less dense bud
  • UV is not connected to increased terpene expression. This misconception is tied to a single paper which only examined the affect of UV on terpene expression in the leaves of hemp plants in veg. The paper even says that while terpene expression did change a small amount, the results are equivocal
  • flushing doesn’t do anything to reduce the amount of chlorophyll or nutrients in the bud tissue. It is useful for fixing problems in the grow media but doesn’t do anything further
  • a dark period before harvest doesn’t do anything other then possibly preserving terpenes due to colder temperatures. Plants need light to photosynthesize and produce terpenes and cannabinoids so putting them in the dark is the opposite of what we should be doing
  • silica is an often overlooked secondary nutrient that helps strengthen plants and trichomes. In his research the use of silica has also helped prevent powdery mildew
  • leaf temperature is more important than air temperature. Typically, healthy hydrated le

Reviews of Sunscreens I've used. Hits and Misses.

As the title suggests, this is my current sunscreen collection, and I'll be reviewing the products and mentioning the ones I love and the ones I don't ! (This post might be half cooked, not very organised and all over the place, but it's my first time, so bare with me :P)

So as I mentioned, this is my first post here (eeep! :D) and initially I thought of sharing my entire shelfie, but I realised that being the junkie/hoarder I am, it'd end up being a terribly long post , hence after much deliberation I decided to post different categories of products separately (sunscreens, moisturisers, serums etc) and after I'm done with that, I shall be making a post with only the products I use in my current skincare routine!

Without further adieu let's get started! Please do like, share, subscribe and don't forget to hit the bell icon!... lmao jk

Skin Type : Oily - Combination, Comedonal Acne Prone, Rosacea Prone,

Major skin concerns : Hypersensitivity, Non inflammatory acne, Sebum Production.

Age : Early - Mid 20s, F

Current Climatic Conditions : Semi- Arid, Dry winter

Specie : Homo Sapien

Height : wait.. I'm not supposed to divulge all these details!

Product reviews :

Note : None of these products have been used by me on a strictly daily basis, except for a week (or two) in a row during vacations, as I rarely step out of the house (lockdown, duh!) and don't apply sunscreen indoors (*gaasp* 😨)
Rest assured, I've reapplied some when out, and have used them on and off in a span of 6 months.

2021 Empties

all of my empties uwu

I did a 2020 empties review which you can find here. This year's empties are much smaller in comparison to my previous year simply because I did not hoard multiple years of empties for my own sanity's sake.

I will also give myself a shoutout to my skincare Instagram. You can follow me if you want more detailed reviews on products. (im pretty inconsistent on posting tho)

My skin is acne-prone, oily T-zone with a normal to dry U-zone. I live in a dry climate with brutally cold winters and hot summers. My main concerns are acne, hyperpigmentation, dry, flaky skin during the winters, and oily foreheads during the summer.

Cleansers:

  • Be Plain Greenful pH-Balanced Cleansing Foam - this cleanser was recommended by Director Pi for really oily skin. As someone with a very oily t-zone, I had to try it out. I did enjoy this cleanser as it had some mild physical exfoliation properties with the green tea powder, overall it was enjoyable to use, but it's kinda expensive? I remember purchasing this from Jolse for a great price though. Alcohol, essential oil, and fragrance-free.
  • The Inkey List Salicylic Acid Cleanser - this is alright, it contains 2% salicylic acid to help combat acne. It's just a regular straightforward gel cleanser that has some ingredients to help acne-prone skin. This is quite affordable and widely available. Alcohol, essential oil, and fragrance-free.
  • Scinic The Simple Pure Cleansing Water - it's micellar water, that's it, that's my review. As someone who does not wear makeup (maybe bb cream at most) I cannot attest to the cleansing abilities. But if you are someone who doesn't need to double cleanse but still wants to do it, micellar water is a great option as your first cleanse. Alcohol, essential oil, and fragrance-free.

Toners:

  • Round Lab 1025 Dokdo Toner - this toner was ranked No. 1 on Hwahae several times. I can't say that I love this toner but it's mildly hydrati

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Making your own clay graphite crucible

First watch this video:

https://youtu.be/UIm7SbyXJeM

This is how we make it in my country, India.

You can learn how they made it but they don't share their ingredients.

All these materials are dirt cheap except Silicon carbide which is not cheap in my country, $5 for 100grams. (maybe it's cheaper in bulk, online price are always inflated in this country)

So why they cost so much? Mostly because they are heavy and are made abroad so logistics and middlemen make a lot of money on these. Workers aren't getting even $7 a day in labor.

Ingredients :

40% graphite flakes (couldn't find locally bought online)

25% fireclay (available at pottery store)

15% crushed high fire clay body like porcelain, particle size 1mm-2mm. (do not use terracotta or other low fire clay here, only porcelain)

10% silicone carbide

5% borosilicate powder (just crushed glassware which are made up of borosilicate glass)

3% alumina powder (from pottery store)

2% aluminium or magnesium powder

All the above material needs to be powered as fine as possible, mesh 200 or mesh 150 will work just fine except for the Porcelain grog where size must be 1mm to 2mm particle size.

Why are we using these particular ingredients:

Goal here is to built a crucible that is able to sustain 700-1400C. While fireclay or porcelain body can sustain 1400C but thermal shock and localized thermal expansion makes it crack. The clay body does not burn or decompose it just cracks, which tells us our material is refractory enough just not able to deal with uneven thermal stress.

We need thermal conductivity within the clay body so that the thermal expansion is uniform across the body, more or less. We use graphite here to aid it.

Fireclay is our binder which itself is refractory enough upto 1700*C it will help us sinter all of this together into one clay body.

Crushed clay body is our grog preventing cracking further by reducing shrinkage when the clay body is dried.

Borosilicate glass powder is source of silica and Boron flux needed to fuse and make glass bonds and help lower melting point of alumina and silica and bond together.

Silicone carbide is excellent thermal conductor like Graphite it helps in thermal stability and uniform distribution of thermal stress.

Finally, alumina powder is included so that it combines with free silica released from borosilicate decomposition.

Aluminium powder or magnesium powder is our "rapid dryer" of clay body. If you do not include it then

These aren't dad jokes...

Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.

This sub is mostly just NSFW puns now.

If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.

Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.
