Blasting on parchment

Ok so; still been reluctant to attempt this and want to discuss it more.

SO normal parchment has silicone coating that will break off when in contact with butane.

So we got some 100% vegetable parchment paper and blasted 1/4 can into it with no leaves. Let it dry and examined; at first there appeared to be white lines left while it dried. (Thought it might be frost; it disappeared when touched and had no consistency) When it was all gone there was nothing visible under light. The paper felt the same.

I notice some of you only use it for the chamber others use it from start to finish.

Pray tell your parchment paper perils...

yooo, i think you'll survive blowing a 1/4 can onto parch.. i think you'll survive up to an entire can dispersed..

i blast onto parch with small runs, small runs loose too much to inside of dish. so i like getting it all!!

that meee. im alive. i use it in chamber with big runs after scrape. scrape comes after initial evap

Might try butchers paper or T-shirt pretreatment paper....idk just throwing out other ideas that may be suitable (they won't leech)

If its non coated then no worries

I did see butcher paper but was unsure of its coating.

Isn't everything coated though? Silicone, vegetable or something else? It has to to keep the paper from absorbing water and sticking; no?

Nah... an acid mix and pressing seals it.....
Easy enough to make sure
Some(butcher paper) are coated(Teflon)...not T-shirt cover pretreatment paper etc

One can is too small; so that makes me not feel good about using it lol.

From wiki

"Vegetable (paper) parchment is made by passing a waterleaf made of pulp fibers into sulfuric acid. The sulfuric acid hydrolyses and solubilises the main natural organic polymer, cellulose, present in the pulp wood fibers. The paper web is then washed in water, which stops the hydrolysis of the cellulose and causes a kind of cellulose coating to form on the waterleaf. The final paper is dried. This coating is a natural non-porous cement, that gives to the vegetable parchment paper its resistance to grease and its semi-translucency.Other processes can be used to obtain grease-resistant paper, such as waxing the paper or using fluorine-based chemicals. Highly beating the fibers gives an even more translucent paper with the same grease resistance. Silicone and other coatings may also be applied to the parchment. Asilicone-coating treatment produces a cross-linked material with high density, stability and heat resistance and low surface tension which imparts good anti-stick or release properties. Chromium salts can also be used to impart moderate anti-stick properties."

Those sound worse than bad tasting wax....

The ones without a coating do that acid shit...its perfectly safe..hard to come by though
Health supermarkets have it
I would choose vegetable parchment as per quote

"In the body crystalline silica particles do not dissolve over clinically relevant periods. Silica crystals can activate the NLRP3 inflammasome inside macrophages and dendritic cells and thereby result in processing of pro-Interleukin 1 beta into its mature form. Chronic exposure to silica may thereby account for some of its health hazards, as interleukin-1 is a highly pro-inflammatory cytokine in the immune system. [26][27][28] This effect can create an occupational hazard for people working with sandblasting equipment, products that contain powdered crystalline silica and so on. Children, asthmatics of any age, allergy sufferers, and the elderly (all of whom have reduced lung capacity) can be affected in much less time. Amorphous silica, such as fumed silica is not associated with development of silicosis, but may cause irreversible lung damage in some cases. [29]

Laws restricting silica exposure with respect to the silicosis hazard specify that they are concerned only with silica that is both crystalline and dust-forming."

Sooo idk how smoked silicone would effect you....not good long term I don't think...
I plan on smoking hash for a good few more decades

What about blasting on the oil slick pads? I bought them and used them a few times but I like parchment better but I blast into pyrex then scrape out onto the parchment.

I've been reading the oil slick pads are safe for us but don't know about blasting right on them?

Food grade silicone is in the new pads, holds up to heat fine but silicone is reactive to butane and can leech into your product.

"For sure. It says medical grade silicone with no logos.....in the medical and pharmaceutical industry silicone contaminants are a known problem..it doesn't matter how pure or whatever, its completely soluble in the solvents we use. Even in the medical industry we are aware and try not to leech but yeait happens. That's why the silicone tubing will become stiff and will lose its stretchiness...silicone shouldn't be used with butane or really even iso or etoh as its still somewhat miscible..the completely pure cannabinoids aren't much better for direct contact"-me

Someone should take them to court if they are misguiding consumers. Especially if people are using their extracts as medicine.

Well I wouldn't advise to blast or store long term..but as fade would say, even oxygen is toxic at high doses, all in the amount...something like that atleast
I don't know..until someone does some research or already has the prior knowledge(I don't feel confident 100% in my own knowledge of the subject). And can tell me assuredly there will be no issues, especially accumulate overtime and all that..
I won't use it...

100% veg parchment did not work with 1/2 or whole can. You can scrape the top but most of it is merged with the paper. >.<

Foil? Lol ...
Did you freeze and peel?

It's a very thin layer. This was 2nd and third spray so it was not much.

I will give it a go though... You can see on the bottom of the paper that its came through in some spots as its shiny and sticky.
