Methamphetamine Melt & Residue Behaviour Reference

This document compiles the entire chat session's information into a structured, verbose BBCode page suitable for forum use and built by AI.

1. PURE METHAMPHETAMINE (HCl)

Melt Characteristics:

Liquefies instantly with gentle heat.

Fully transparent liquid — no cloudiness.

Thin, watery melt that moves rapidly across glass.

Minimal bubbling; any bubbles pop immediately.

Forms a uniform melt pool with no unmelted patches.


Residue Characteristics:

Recrystallises into clear, needle-like shards.

No fog, chalk, or powdery film.

After full vapourisation: almost no residue.

Brown or black marks only occur from overheating.


Decomposition Clues:

Overheating produces sharp ammonia-like smell and brown streaks.

Pure MA does not caramelise unless exposed to excessive heat.


2. MSM (Methylsulfonylmethane)

Melt Behaviour:

Melts slower than MA.

Melt is thick and syrupy.

Cloudy melt with persistent bubbles.

Moves sluggishly.


Residue Behaviour:

Leaves white crystalline residue that doesn’t fully liquefy again.

Chalky recrystallisation.

Fogging on glass builds over multiple cycles.


Decomposition:

Forms a persistent white film rather than caramelising.


3. Sugars (Glucose, Lactose, etc.)

Melt Behaviour:

Thick, sometimes yellowish melt.

Caramelises easily.

Sticky and uneven melt pool.


Residue Behaviour:

Brown or black tar spots even at low heat.

Sticky residue that cannot recrystallise.


Decomposition:

Sweet-burnt smell.


4. Isopropylbenzylamine (iPBA)

Melt Behaviour:

Higher melt temperature than MA.

Thicker melt, slightly opaque.

Moves sluggishly — forms globs.


Residue Behaviour:

Opaque, chunky recrystallisation.

White granular crust after vapourising.


Decomposition:

Harsh chemical or plasticky smell.

Grit-like residue.


5. Caffeine

Melt Behaviour:

Does not fully melt.

Frothy, uneven bubbling.

Yellowish or brownish melt.


Residue Behaviour:

Brown crust.

No recrystallisation.


Decomposition:

Bitter, burnt smell.


6. Lidocaine (and similar local anaesthetics)

Melt Behaviour:

Oily, thick melt.

Aggressive bubbling.

Hazy liquid that never turns clear.


Residue Behaviour:

Waxy coating.

Opaque plate-like recrystallisation.


Decomposition:

Plastic/electrical burn smell.


7. Ephedrine / Pseudoephedrine Contamination

Melt Behaviour:

Melts slower than MA.

Slightly yellow melt.

Longer-lasting bubbles.


Residue Behaviour:

Yellowish film.

Mixed clear + cloudy recrystallisation.


Decomposition:

Sharp medicinal smell.


8. Industrial / Unknown Contaminants

Melt Behaviour:

Unpredictable melt.

Strong bubbling.

Multi-coloured or tan melt.


Residue Behaviour:

Sticky patches.

Pitting of glass.

Multi-colour crust.


Decomposition:

Harsh solvent or burnt-plastic smell.


9. Purity Levels — Quick Visual Diagnostics

Excellent Purity:

Clear melt

Fast, thin movement

Glass-clear recrystallisation

Minimal residue


Medium Purity:

Slightly cloudy melt

Slower movement

Patchy recrystallisation

Light fogging


Heavily Cut:

Thick or sticky melt

Persistent bubbles

White or brown residue

Cloudy recrystallisation

Tar spots


Fake Shard / iPBA Indicators:

High melt temperature

Opaque melt

Chunky recrystallisation

Intense chemical smell


10. Behaviour Patterns That Always Signal Impurities

Caramelisation = sugars or overheated organic cuts.

White crust that won’t melt = MSM or iPBA.

Sticky brown patches at low heat = sugar cuts.

Opaque melt = heavy adulterants.

Foaming = caffeine or lidocaine.

[sarcoth]

I hadn't used meth in years and didn't use really heavily then just mainly one or two weekends a month for a few months of the year scattered across a 2 year span. That was before I've gotten a random delivery from the dope fairy twice now when I've found random (or as random as working at a cheap hotel with number of meth users around can be. I kinda feel it's a karmic reward for cleaning up after the nasty guests) ice now in the last couple weeks. First time was a little bit, like a half gram to 1g, baggy and this time it was probably around an 1/8 Oz best guess (sorry not the most experienced at judging the weight of powder.) 

The first one I had a light bulb i carved up into a bowl after did a little sample toot in my nose to see if it was what I thought it was and after I didn't feel any fent in it.

gave up on trying to use foil before I drilled out a light bulb to use. It smoked great in my light bulb bowl crystals on the glass all around my little crystal i dropped in it bubbled up and rolled around the bulb fine nice and smooth, not sluggish, it was like water without much flavor either. I got a stout kind of buzz off that little baggy the size of a postage stamp overall a pretty good Friday night and I worked during the day and was asleep Saturday night working Monday morning no problem. It had me up all night the first night Friday and into the evening Saturday the next day until I didn't really have to much of a problem eventually dozing off more like too much coffee and energy drinks before bed than any kind of high. With plenty of energy not a lot of the euphoria/twitchy short attention span I'd feel around 5 to 6 years ago when I last smoked any of it. Back then I think it was a stouter product cause I'd have all the energy of a rabid squirrel and the attention span of a gold fish.

This second batch I found I went out and got an actual glass pipe. And it seems like it's weaker than the one I had a couple weeks ago. The crystals themselves look good like text book ice. Thing is it doesn't crack back and crystallize like the last little sack did and doesn't seem to hit as hard either. The first couple hits it felt like it was going to be good I was working my jaw and couldn't sit still and felt social. since those first good hits though I dunno if the crystals I've been picking have more cut or what cause none of them look different, but they're not as stout as the first couple hits. So far every hit when I put the lighter to it there's no crackback to speak of it frosts the bowl and stem up white residue that will melt with heat and with little snow flake looking spots in places and the puddle doesn't look very crystal like at all just like some little bitty yellowish grainy crystalish residue in a puddle. It gets like water rolling around in the bowl before it solidifies and it doesn't burn up/caramelize with a Bic lighter and I haven't used the torch on it at all since it smokes up plenty with just my regular cigarette lighter.

Is my best bet to later today when I can get some Epsom salts and dry them out and then use them to dry out some acetone and wash it really thoroughly? I want it to have an actual kick and not waste a bunch of it burning it up and not getting a good buzz. matter of fact shortly after I post this I'm going to crash out for work tomorrow and I don't feel like I'll have too much trouble dozing off and I just found that second batch today and smoked a bowl around lunch and hit it a few times off and on since then. I was hoping with this batch I could use it to take my mind off craving 7hydroxy I've been taking too much of cause with the first little baggy I found I barely touched it at all that weekend and didn't start to feel twitchy like I would have without smoking the ice.

Edit: as a side note this second batch so far hasn't tried to burn up in the bowl at all unlike every other time I've had any. Even under just the heat from a bic every other time I've smoked it by now there would be a little bit of blackish/burnt up residue in the bowl around the edges of the puddle or just anywhere on the bowl where it would get thin on the heat.
