Food safe pitfire ?! (Made of Australia quartz sealer)

#pottery #art #pitfire
Hey there potters. I have been working on testing this liquid quarts sealer to see if the claims it made were true. I must say PLEASE DO YOUR OWN TESTING AS WELL, do not rely on me alone. I have been testing this and by what I have tested it's very safe and sealed.
I have and will continue to drink from this,
big shout out to made of Australia for the sealer.

Water Absorption test for food safety: you measure the pot dry weight and then after 24 hours socked in water. If the weight difference is less than 2 precent it is considered food safe.

How is wood food safe?

[@shuvalassaf]

@@hot_pony_unicorn wood utensils are considered food safe only if allowed to dry completely, and washed after every use with detergents. But not very hygienic.

[@darrenscott7312]

Yep that stuff is great. Glad I’m in Australia. I’ve used and am very happy with it. The stuff for sale on their website is gas fired saggar. FYI they do say won’t work on anything that is not porous. Like raku glazed.

[@jimkillough8340]

Thank You! Excellent Video. This subject is of vital importance to my indian pit wear. So many people ask if it is food safe and health promoting. You are the best. See ya Dirty Potter!

[@darlink57]

Can’t wait to try this! Excellent!

[@teablooded]

I can't wait to see actually functional pit fired mugs!! Also, speaking of new tech, has anyone tried that microwave kiln?

[@sheilathepotter6636]

Hm.. very interesting! I would do tests over a long period of time to see how well the product lasts. Coffee is quite acidic and over time with repeated use the combination of coffee, washing with an abrasive sponge brush, or dishwashing might cause the product to wear off. I wonder if people have done long term tests to see if it survives extended use. Also, bisque work is still quite fragile compared to high fired work so people will need to be slightly more careful when using the pieces. I like the idea of using the product to seal non food items, like vases or house plant pots or something.

[@darrenscott7312]

They have restaurants using plates treated with the product since 2014. So home use would not be an issue

[@HatefulPerfection]

@@darrenscott7312 Can you point to which restaurants because as far as I can tell, on other materials, these barriers seem to be temporary

[@lulzgibberish3772]

what an incredible product

[@johnathantucker1338]

If you had enough, could you just fill a basin and dunk/soak the pieces in?

[@johnathantucker1338]

also, can you add it to unglazed high fired pieces?

[@darrenscott7312]

@@johnathantucker1338 they say any non porous. But vitrified. So unglazed high fire would work. Unfired bone dry would not work.

[@jameswills2205]

I looked into this stuff as an alternative to glazes, even in Australia it's bloody expensive $150/ltr 😳

[@darrenjackson5]

Woah! This is awesome!!

[@TheRedwolf495]

Nice!!!! I'm gonna try some!

[@hobblecreekpottery]

Mind blown!

[@lynncombel1106]

Thank you!!!!!

[@mirelapopovici9077]

Thank you for this. Should this be used on micaceous clay or would you leave it as is? As there are people cooking in it buffed and sealed with oil, like a seasoning on cast iron, or should I just seal it?

[@donm6578]

But will coffee or other acidic things absorb the liquid quartz and be potentially poisonous?

[@anonymouswhite7957]

A bit skeptical too... but the website mentioned that it was made from silicon dioxide and water carrier. Silicon dioxide is inert so it’s pretty much safe (unless inhaled, can cause silicosis, but well anything that got to do with pottery can cause silicosis), not really sure about the carrier though. It is also stated that they are already approved by the EU food safety standards. Tbh by reading on how it works, im more concerned about the untreated micro gaps of the unvitrified clay that could leach out to the food rather than the liquid quartz itself...

[@petercorazo]

Doing a bit of research, found out that it's made out of the same material as ceramic glass spray for your car, SiO2. wondering if That would work the same?

[@amymcknight6674]

I was wondering the same thing.

[@RebeccaRoseS]

I just came here to ask the same question. I found a spray for £8 for a car.. bit cheaper but food safe???

[@garnek90]

BUT, will it work on raku fired pieces? i know raku is a different process so maybe something else is making ceramic not food safe. idk, i'm still learning, all suggestions are welcome

[@darrenscott7312]

This would only work on naked raku

[@wonderwond]

silicon dioxide is the main ingredient, they have a food safe grade of it, its also used in a lot of foods we eat, but Im not sure about this one as to it may not show all of the ingredients, all of humanity many centuries ago have been eating and drinking out of fired clay, the reason they say its not food safe to eat out of is because of whats used in the pottery, such as milk or other foods that build up in the poors of the cups or bowls, but humanity has survived, you could re sterilize your pottery after so many uses of course, who is to say a lot of the plastics and such we eat from is good for us either, this product has promise for sure, but the price is ridiculous, you can buy silicon dioxide food grade off amazon and ebay way way cheaper and maybe mix with water or alcohol as a delivery process for it. since Indians many years ago used corn starch wonder if you could add some powdered corn starch to help use as a binding agent mixed with the silicon dioxide and water and slightly heated ??

[@hot_pony_unicorn]

Why exactly is it pottery not “food safe” if it’s not glazed when wood is food safe?

[@johnathantucker1338]

"food safe" wood is generally treated with waxes or oils, the end goal is to prevent water absorbion or closing pores. Unglazed ceramics arent food safe because things can become stuck in the pores and grow bacteria

[@anonymouswhite7957]

The minerals/metals in the pottery could leach out to the food/water you are using it for (pit firing especially can’t get the clay to a vitrifying state, cause of the no glaze and low temp firing). Wood is a lil safer since they are organic most of the stuff that gets out is microbes and the degraded wood (which is why cleaning, sanitation, and reapplying finish is needed to maintain proper food safety). I think both are technically not food safe on their own, the glazes and finishes that coat their surface are ones that do.

[@EarthNationCeramics]

Amazing answers ,both of you.

[@ThruHerSkull]

What is that flat sponge thing you use in your videos?

[@wonderwond]

what did it taste like when it got on your mouth ?? water or alcohol ?

[@jingleberries4567]

Can I use this on my cone 10 rio red aardvark?

[@EmberGlowTreasures]

Would this also work on Raku fired pots? I know Raku is a very different process but I am very curious!

[@darrenscott7312]

Naked raku - yes. But not glazed surfaces

[@jackgreen412]

You've been drinking tea out of the bottle for months?

[@joemekkena293]

it would be very useful to talk to you and bounce my idea off

[@carriec7596]

Does this work on raku fired pieces too???

[@leonibenzaken2581]

Sadly no. It will only work on non glazed surfaces. But there are some good safe Raku glazes out there.

[@smokertwashington]

Sounds like eating chemicals bro?🤨🧐
