#burn test

[sarahthecoat]

yep, my favorite fabric thrift store does this, and periodically teaches classes too.

Get yourself a fabric store that will light your fabric on fire for you

No but legit I asked what the fiber content of something was and the guy didn’t know so he cut a chunk off and lit it on fire and felt the ashes and was like. Yeah this is mostly cotton with a lil bit of silk. And that was the moment I knew. This is it. This is the fabric store for me. Also that guy is marriage material. Not for me but damn some person is gonna be so happy with him.

me: hey I like your sweater

random stranger: thanks I just got it! it's soft and woolly

me: it looks it! can I test?

them: yeah go for it. they hold out their sleeve

me: cuts off a small portion, burns it, and plays with the ashes

Hello fiber friends!

It has been a bit since I posted anything original in a while. I have been busy with real life and ✨️planning projects✨️

In efforts to plot the next few steps of my current project, I have a fiber content question.

I purchased some mystery fiber from my Guild today, and this one treasure (out of many) is amazing and has a stunning color. I'm going to make a shawl out of it and sell it through my Guild's program this winter.

But what is the fiber content? I did a burn test and have some notes, so hopefully, somebody with more experience can point me in the right direction here!

This is the fiber. I now have 6 cakes, weighing something like 800-900 grams total. I haven't broken out the scale or figured out yardage yet.

I cut off a sample and burned it, then realized it was NOT the results I was expecting.

It lit up quick with a bright yellow flame, and the first time, I startled and dropped it in the dish. The second time (pictured) I was prepared but had a much shorter sample this time. The two pictures are about one second apart.

When burning in the dish, the flame diminished pretty quickly but continued to smolder down the length. The thicker part of the yarn didn't burn all the way and self extinguished. It smelled somewhere between paper and a slightly green wood but didn't produce any noticeable smoke.

The ash is very fine, but smeared the dish with a little grease when I picked it up. (As seen in picture two above) The part that didn't turn to ash did crumble a bit in the fingers with a little pressure but is still recognizable as fiber. It is very soft ash, with no lumps.

I think this is cotton! But if I'm going to sell it, I want to be a little more sure than "yeah, it's a plant fiber and cotton is the first one people think of".

I was honestly expecting acrylic with the vibrancy of color, but I am stoked it is not!

Synthetic fibers aka plastic fibers don't burn they melt which is not only not fun but also releases not good for you fumes. I would say cotton is probably your most economical choice for crocheting a flammable goat. At least in the good old US of A. Sugar and Cream or Peaches and Cream tend to be fairly economical options. as far as stuffing goes Straw and Newspaper would certianly be flamable however cotton balls would probably work too

Wool while a natural fiber is pretty dang fire resistant with an ignition point that's nearly double that of cotton. It has to do with the chemical and physical compositions of the keratin strands and all the fun things biology things like cellular composition and cell walls. Fun tidbit of information, it is possible to identify the composition of random fibers by observing how they behave when set on fire.

i made smthn but if i post it it’ll blow up like the duck sweater and haunt my notifs for months

Stephanie: "Did you get it?"

Tim, scoffing: "Of course I did. *unwraps the vase from bubble wrap* It's the exact same, one of the three original vases made."

Stephanie: "Wait. The old one had a nick, right there on the shoulder. *uses a Batarang to recreate it* There."

Tim, setting it down carefully and smiling: "Perfect. I think we just got away with it."

Jason, reading on the couch: "He'll know."

Stephanie: "How? You'd have to--"

Alfred: "Is there anything you guys want for dinner?"

Tim and Stephanie, immediately: "No."

Alfred, frowning slightly: "Very well." He walked over, both Tim and Stephanie trying to play it cool as the butler adjusted the vase on the table.

Jason looked up from his book.

Alfred: "I'll remind you again, Master Timothy that skateboards are not permitted inside the house."

Jason cackled at the expression that Tim and Stephanie made.

--------------------------------------------------------------------

Bruce: "How did you know? Technically speaking, it's the same vase."

Alfred: "I have a contact at the auction house where you bought the second one years ago."

Bruce, clearing his throat: "Yeah, Jason accidentally kicked a ball into it."

Alfred, raising an eyebrow: "He threw a Batarang at it because you wanted to make him more comfortable."

Bruce:

Alfred: "I do wish you'd all stop adding that nick back."

The Burn Test

Different types of fiber burn differently. Cellulose, animal and synthetic fiber all respond differently to flame, and analyzing how they respond to flame (from speed to smell and type of ash) will help you identify the specific type of fiber. This is important information to help you determine what specific dye will work best on each particular fabric.

We will use "change magic" to form ourselves into 3 groups of 2 or 3 people to work together to identify a series of fabrics and determine whether they should be dyed with fiber reactive dyes, acid dyes, or not use dye at all, instead coloring via surface treatments like paint.

Preparation and Supplies

A flame source. We will use a lighter.

Tweezers. Some fabrics can burn unexpectedly quickly, and tweezers ensure your fingers stay safe from the flames.

A fireproof dish. Dropping flaming fabric onto a flammable surface – or even worse, your fabric stash – could spell disaster. Always use a fireproof dish under your burn testing area.

A glass of water. Just for extra safety, I like to keep a glass of water nearby to extinguish any flames in the case they get out of control.

A ventilated area. Burn tests should be done in a space with plenty of ventilation. We will use our exhaust fan during our burn testing exercise.

Burn Test Chart, which will help you identify your fabric. We will have copies available in class, and a digital version of the burn chart is also available for you on canvas.

Your fabric swatches! You’ll each receive a series of fabric scraps to use for your burn tests as well as a log to record your observations.

The Burn Test

Hold your lighter in one hand and your fabric in tweezers in the other hand. As you bring the fabric and the flame together, note how the fabric reacts, how the flames burn and what the ashes are like. These components of the test all provide great insights into the identity of the fabric.

Some questions to consider:

Does the fabric curl away from the flame? Does the fabric catch immediately, or take a while to light? Are the flames bright? Is it burning quickly, or does it smolder out? Does the fabric simply melt as the flames sputter along? What smell does the smoke give off? What shape are the ashes? Do they fall apart when you touch them, or do they stay hard? Are they congealed onto the fabric?

Please be careful when examining the ashes, as they may still be hot or contain embers.

Use the burn test log sheets distributed during class to collect your burned fabric sample and observations described above. Use the burn chart to do your best to identify the type of fabric you have tested. Scan or take a picture of the completed sheets and post to your blogs to receive credit for your research. This will be graded as part of your blogcheck #1 grade.

I found a great post about burn tests that I used as a resource for this post. Both of these images came from that post. Check out the burn test info directly here.

It is interesting to go look back and realize how old these pictures are.

Been working on finding a candle recipe that works for me for since like 2020.
