i made my own sodium silicate and now im going to add it to perlite to make model rocket nozzles,a forge, a foundry and finally a rocket stove and i must say that I LOVE PERLITE! it is the best
I have used perlite like in the video for filtering wine. After the fermentation and settling, the bulk is syphoned off from the top, and then the lower left over bit with all the yeast still in it is fed through a rotating drum that is drawing a vacuum, the perlite is slapped on in shovel loads and then a little water is sprayed on it so it sticks, you build up a thick cake of this stuff, then the tank underneath is filled with the muddy wine, as it rotates it sucks up the liquid, the nice clear juice gets sucked through, and the crap stays on the perlite, which you scrape off as you go. It is one of the most tricky things I have ever learnt to master. Get it wrong, just a little bit, too wet, too dry. too slow, too fast, too much vacuum and splat, it all starts falling off and makes a mess, back to square one.
Thank you for your comment! Rotary vacuum drum filters are used in a number of industries for dewatering mixed liquids and solids, water recovery and recycling, and collection of valuable solids that would otherwise go to waste -- important steps in helping industries protect the environment and be more sustainable. Typically we see the vacuum pump used to build up a thick layer of fine perlite on the septum prior to introducing liquid needing to be filtered. So-called "plate and frame" filter presses also commonly use perlite to protect the longevity of the septum and provide better filtration. There are a number of fine articles on the different types of filtration and equipment using perlite found on the Perlite Institute website here: www.perlite.org/library/#filtration
Have you noticed any settling of the perlite of the walls or any where. I was considering using this as insulation but I have no knowledge or experience with it?
Thank you for your question. In general, perlite dust is mainly considered to be a nuisance dust which can be managed with the correct use of Personal Protective Equipment (PPE). This being said, it is important to refer to each manufacturer's Safety Data Sheet (SDS) for specific guidelines for use and exposure and consult The Perlite Institute (www.perlite.org/) for the latest information related to the topic of perlite in the environment and workplace.
Thank you for sharing! While each has its own distinct properties, both perlite and vermiculite are used in numerous industries and we support the use of both in different applications. Both are 100% naturally occurring, are relatively pH-neutral, and are safe for handling. Where perlite excels is its durability and insulating ability. Perlite maintains its structure for longer, which is important for horticultural soils needing consistent drainage, aeration, and water-holding capacity. Because of differences in structure, perlite also contains more trapped air by volume meaning it excels as a thermal insulator.

"Construction Grade" perlite (also known as "Plaster/Concrete Grade") is produced to meet the ASTM C332 specification for insulative value and compressive strength. It is designed to withstand crushing forces when added to concrete and other aggregates in a transit type mixer. There are some finer grades which can be made to retain insulative properties, but generally speaking, crushing and breaking the glass bubbles of which particles of perlite are composed would negatively affect insulative value.
I was once on a bike camping trip, 7 weeks, my brother and his GF bought a cheap new sleeping bag along the way. For several days they couldn't figure out why they had strange itches and irritations all over, turned out the bag was insulated with FIBERGLASS! (true story)
Oregon OSHA considers perlite dust a nuisance dust only. For those wishing to limit their dust exposure, example Personal Protective Equipment (PPE) are described in the supplemental statements of our Safety Data Sheet (SDS), available for download on our website at www.perlite.com.
Perlite is completely inert, you can put it back on the ground and it will be just like another rock. Recycling is mainly important for consumables that use trees or would hurt the environment if placed back in nature.
@@jonathanpayant5423 ...trees are renewable and need to be thinned out to allow photo sencelessness of the forest floor. The real culprit is the internet you humans are using to read this very informative message..:)

In this video, the reference to crushing and screening refers to the large chunks and blocks of raw perlite ore that come out of the earth which must be ground down to reasonable size prior to being fed into a furnace. If the size of the ore particles are too large (large volume relative to surface area), the heat will not penetrate fully to the core of each particle, causing uneven expansion.
I think its because EPS is much cheaper, but long term Perlite will have the same exellent insulation properties and wont compress or be destroyed by ants/rodents.

Thank you for your comment. Supreme Perlite Horticultural Grade expanded perlite products are OMRI Listed and approved for use in organic agriculture. That being said, perlite is a mineral -- a volcanic rock which we expand with heat -- and not an organic substance per se.
It's not particularly dangerous. While it's always a bad idea to be constantly breathing any kind of dust, for perlite dust it's probably really not that bad. The perlite is an amorphous glass, not a crystalline silica, so the dangers of silicosis, COPD, and carcinogenicity are really all very low.
Or call your local perlite manufacturer 😉. Here is a link to our contact form, www.supremeperlite.com/contact/, if you're looking for supply in the U.S. or Canada.
