Coloured Phunnel & Bowls

[barrenwizard]

Hi guys, I went to a pottery maker in my area and asks for her to make few pieces of phunnel for my own experiment and asks if the choices of colours are plenty. She tell me that there's only a limited choice of colours within a clay that exist in the WORLD. Which doesn't surprise me when I asks why is there other colour than (Showing a pics from my cell phone of those coloured phunnels to her). She warn me that it could only be done by mixing it with lead just like colour pencils. Which will create a wide variety of colours. Problem is lead is poisonous, hence the ban of those China Made toys and Colour Pencils and such.

She did asks me a very good question. How many types of colours of clays can you find the WORLD? Guess what, she's right, what other clays that would come in other colours? So far its the normal rusty red, chocolate, tan, green and black. Other than that its up to their skills to overlay each layer of clay. That's what I heard from her.

So here's the rough info on Clay and Lead.

LEAD

Health effect Lead is a poisonous metal that can damage nervous connections (especially in young children) and cause blood and brain disorders. Because of its low reactivity and solubility, lead poisoning usually only occurs in cases when the lead is dispersed, like when sanding lead based paint, or long term exposure in the case of pewter tableware. Long term exposure to lead or its salts (especially soluble salts or the strong oxidant PbO₂) can cause nephropathy, and colic-like abdominal pains. The concern about lead's role in cognitive deficits in children has brought about widespread reduction in its use (lead exposure has been linked to schizophrenia^{[citation needed]}). Most cases of adult elevated blood lead levels are workplace-related.^[14] High blood levels are associated with delayed puberty in girls.^[15]

Older houses may still contain substantial amounts of lead paint. White lead paint has been withdrawn from sale in industrialized countries, but the yellow lead chromate is still in use; for example, Holland Colours Holcolan Yellow. Old paint should not be stripped by sanding, as this produces inhalable dust.

Lead salts used in pottery glazes have on occasion caused poisoning, when acid drinks, such as fruit juices, have leached lead ions out of the glaze.^[16] It has been suggested that what was known as "Devon colic" arose from the use of lead-lined presses to extract apple juice in the manufacture of cider. Lead is considered to be particularly harmful for women's ability to reproduce. For that reason, many universities do not hand out lead-containing samples to women for instructional laboratory analyses.^{[citation needed]} Lead(II) acetate (also known as sugar of lead) was used by the Roman Empire as a sweetener for wine, and some consider this to be the cause of the dementia that affected many of the Roman Emperors.^[17]

Lead as a soil contaminant is a widespread issue, since lead is present in natural deposits and may also enter soil through (leaded) gasoline leaks from underground storage tanks or through a wastestream of lead paint or lead grindings from certain industrial operations.



Former applications

• Lead pigments were used in lead paint for white as well as yellow, orange, and red. Most have been discontinued due of the dangers of lead poisoning. However, lead chromate is still in industrial use. Lead carbonate (white) is the traditional pigment for the priming medium for oil painting, but it has been largely displaced by the zinc and titanium oxide pigments. It was also quickly replaced in water-based painting mediums.

CLAY

Clay is a naturally occurring material composed primarily of fine-grained minerals, which show plasticity through a variable range of water content, and which can be hardened when dried and/or fired. Clay deposits are mostly composed of clay minerals (phyllosilicate minerals), minerals which impart plasticity and harden when fired and/or dried, and variable amounts of water trapped in the mineral structure by polar attraction. Organic materials which do not impart plasticity may also be a part of clay deposits.^[1]

Clay minerals are typically formed over long periods of time by the gradual chemical weathering of rocks (usually silicate-bearing) by low concentrations of carbonic acid and other diluted solvents. These solvents (usually acidic) migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals are formed by hydrothermal activity. Clay deposits may be formed in place as residual deposits, but thick deposits usually are formed as the result of a secondary sedimentary deposition process after they have been eroded and transported from their original location of formation. Clay deposits are typically associated with very low energy depositional environments such as large lake and marine deposits.

HISTORICAL AND MODERN USES

Clays exhibit plasticity when mixed with water in certain proportions. When dry, clay becomes firm and when fired in a kiln, permanent physical and chemical reactions occur which, amongst other changes, causes the clay to be converted into a ceramic material. It is because of these properties that clay is used for making pottery items, both practical and decorative. Different types of clay, when used with different minerals and firing conditions, are used to produce earthenware, stoneware and porcelain. Early humans discovered the useful properties of clay in prehistoric times, and one of the earliest artifacts ever uncovered is a drinking vessel made of sun-dried clay.^{[citation needed]} Depending on the content of the soil, clay can appear in various colors, from a dull gray to a deep orange-red.

I'm pretty sure the clay used in a hookah bowl itself is not colored. The phunnels are white on the inside which lead me to think they aren't even clay and if they are it's only the outside surface of the bowl that is colored.

Or I could just be totally wrong seeing that I don't know shit about pottery. Edited October 28, 2008 by click

The glaze on the outer portions of the bowl is harmless. Edited October 28, 2008 by mitchard

[MechAnt]

Well, from what I understand, phunnels are not necessarily made of clay or porcelain but rather grout. It's a material that gives the sort of grainy texture that it has. Perhaps they have coloring that doesn't have lead?

[barrenwizard]

I'm unsure of it either, its best that we create an awareness first cause some times teh tiniest little details might be the main cause of serious illness in hookah smoking.

[cr15p3rz]

the funnel bowls arent made out of clay plain and simple, and they're glazed for color

[cotsi95]

The glaze is harmless....they use glaze on everything from mugs to....well hookah bowls lol dont worry about it. Im sure the smoke coming from the hookah is more harmfull to your health then the glaze lol

[Voski]

The clay is white once it is fired and it is very rough. The glaze on the other hand just basically leaves a layer of glass around the clay

personally I don't think eric hates us enough to want to kill us. Now the Chinese phunnels i don't know...

I'vr spokenm to him before about the phinnels. They are all non-toxic safe glazes. Now, the chinese rip off phunnels were something I was thinking about as well.....

[barrenwizard]

Man... I hope that those china made bowls or phunnels is inserted with lead. I mean after the Melamine contamination, who knows to what extend they would reach just to get their profits.

[drabin]

anyone here a lab scientist or anyhting of the sort. or anyone here have the capabilities to runa test on a chinese phunnel. It would probably calm alot of people. I bought one for a close friend for her bday and im sorta worried now never though of the lead part. but then again thats china for you. And i think that shes smoked it at least 5 times now and hasn't gotten sick so it shoudlnt be a problem

Someone buy this and test it. Seems simple.

If you guys want a super duper answer my chem teacher might let me crush up a phunnel bowl and test it for lead but I won't be using one of my bowls if that is the case.

I am pretty sure my Tangier bowl isn't glazed all the way into where you put the shisha. It is glazed though where the handle is. Is that bad?

I can feel a difference when I am touching it. Edited October 28, 2008 by newjacksm

[Voski]

Its glazed all over except the bottom and the down shaft. Or where it is white and rough.

Mine feels different though Mine feels different around where you put the shisha in and you can actually see the cut off of where the glaze stops on my handle. Edited October 28, 2008 by newjacksm

Pics? Sometimes whoever makes these bowls gets lazy and doesn't actually entirely smooth out the clay on the handle part so it will still be rough after glazing. Put your finger into the hole from the bottom where you would put the rubber and feel around. Then feel the glazed part and see if it feels exactly the same.


by rubber I meant grommet but I figure saying rubber would get me siged.

just took pics im gonna upload them in a bit, like i actually took a good look now and the rim of the bowl is turning white I have Mint Irish green. I hope I didnt smoke any lead

Is this a real phunnel or chinese?

[newjacksm]

this is when i first got my funnel you can see in this picture the glaze stops but its still sorta smooth like it doesnt feel like the inside of the bowl



and it looks like when i first got it it still had a white rim (few)





thats what it looks like now sorry camera photos

[newjacksm]

Could I be possibly smoking paint? and if I am is the paint at least leadless!?

[Voski]

The clay is fired at a way higher temperature then what your coals make so I don't think your smoking the paint. I am not sure, do you feel any difference in your health. If your worried about it I would say get a new authentic bowl and use that just for your own well being.

[newjacksm]

I bought this at MNH this is a small tangiers authentic bowl I got it mid summer

[liquidglass]

lol are you fucking serious man? First off the clay lady you talked to doesn't know what the hell she's talking about if she doesn't realize that you can paint and glaze an object. If it was "made into it" the whole bowl would be colored not just the outside.

then, why didn't you just post a link rather than a long explanation as to why lead is bad for us?

[newjacksm]

im still really scared as to if my bowl is half glazed or not im pretty sure its not at the top if it would make a difference and if im inhaling lead.
