I've got 4 cans of Ronson.

The BHO tube is valved so I'm supposed to be able to fill it with butane and then sling it all in the freezer for a while to let soak.

I hope the 4 cans is enough.

So I found a bag of these little star shaped silicone molds a while back in Aldi for 2 quid ish, they're about the size of a 50p piece........

Aye I've seen a company linked to the Skunkpharm boys that make special silicone mats that don't react with butane unlike regular silicone.

I'm after one of those, I like silicone but butane doesn't.


Do you know what your slick pad is made out of?

I threw the paper it out it came with I can only.remember it saying its food grade silicon and heat and cold resistant think it was -50 - 400° or something like that its exactly the same as the oil slick apart its got a black edge instead if green

I got the Mrs to get me nice pyrex.to spray into but on bottom of the dish its got bastard pyrex in concave writing on the fucker lol not good for scraping so I just sat my slick pad in there instead worked a treat to be fair ;)

That says it's food grade sillicone, you don't want to be using butane with that man.

Read this the guy from Oil Slick sent to Skunkpharm.........

"Hi Greywolf,

I am sure you know, silicone swells in the presence on non-polar solvents. Hexane is actually used as a “swelling agent” for silicone tubing to allow for an easier connection.

Theswellingeffect is the primary reason why silicone makes a poor compatibility choice when selecting a material to come into prolonged direct contact with non-polars.

As you must also be aware, chemical contamination from “extractables” in silicone materials, (in a procedure such as you are describing) is due almost entirely to the physical release of low molecular weight siloxanes, and other impurities from the manufacturing process.

This is why Tygon 3350, or SaniTech-Ultra, are made with platinum cured silicone rather than the more common peroxide cured variety. This is also why we use platinum catalyzed USP6 silicone in our pads. (rather than peroxide/food grade).

As far as I am aware, we are the ONLY company doing this. The cost of material for a simple “baking mat” would be prohibitive in that industry.

For the record (sometime I feel like a broken record)We do not sell the Pad to spray directly onto. Many (many) folks do, and when we realized it (july of 2012), we switched the silicone we use as our raw material as a prophylactic measure.

We also removed the Logo from our pads, because we feared that immersion in non-polar solvent could act to weaken the bond between that thin layer of logo silicone, and the pad beneath. As concerned as we were about the logo….i cringe when I see folks spraying into parchment. The matrix of silicone in common parchment paper (non-Quilon / silicone coated) is extremely fragile compared to a pad. I imagine the violence of swelling and shrinking on that scale would be tenfold compared to the effect that prompted our own change of material.

The physical wear of swelling/shrinking/swelling/shrinking along with the various stresses inflicted by the innovative public (razor blades, torches etc…) make any sort of performance warranty unmanageable.
So we make em as pure as it gets, and when people ask us….we tell em that if they insist on using them this way, to please discard them if they notice any physical degradation.


I would refrain from cutting the pad to perform your testing, as this will expose the inner weave. Once cut or torn, the physical consequences of swelling could lead to damage along the exposed area.

Let me know where to send it, and I will get a Pad out to you today. Always happy to hear your thoughts. I redacted about 2 pages of hyper technical diatribe from this email…. because I figured you have likely done your own research regarding Pt cured silicone, and the various plasticizers that are used in food grade silicone. This is understandably a topic quite close to my heart; and I will be vary happy to discuss at length should you have specific questions (or non-specific musings?).

Also, should you require it, you have my explicit permission to share anything we discuss with whichever forums you are involved in.

Regards,

Joshua"

It has this disclaimer at the bottom of the ebay listing too.....

*We do not recommend to blast on the WAXY!™ Pad. Butane peels off silicone. The material can be put on the pad right after the you scraped it out of your dish.
