does it get brittle, or does it stay togather? I am looking at making a see through guitar pickguard, and think that would actually look really cool.

@jaywilly471 both Thicker stuff will stay together better

wow i work at an acrylics company and some of the clear tube we have has done this over a period of time can only now assume that the fumes from the liquid and powder mix we make have caused this, this video has been surprisingly useful thanks fella

@devilboy303 You are welcome. I tried to post some more info but YT has some sort of filter that I do not understand that throws ERROR when I try to post comments sometimes. YT is great, but they should leave well engouh alone.

Alcohol destroys cold acrylic too.

[CyberDruidtheModGod]

Not in the same way. Try it and see, I don't know why anyone would want to refute the clear evidence in the vid...seems contrary to logic.

@jaywilly471 hi i work on a company that fabricate acrylic boxes, sign holders, etc,etc,etc, im learning every technique about gluing, flaming etc, is very interesting.

V.interesting...But remember, Thou shalt not put thy left hand in front of cutting edge.!!!

@jaywilly471 cracks decrease the impact resistance a lot.

But you can reduce this by glueing it with a flex glue without solvents on the non-cracked zone.

@poosaypirate no it is a bit different:

The flame makes the surface to melt andwhen flame is removed, it rapidly cools down causing tensions in the plastic. Tension level decreases with distance to the edge.

Once a chemical is used which is incompatible (but does not dissolve it), it will cause cracks (it is called stress-cracking).

These cracks suck in the liquid and the process continues.

(it can be stopped by washing it off).

@artsycalgal

yep

Plexiglass, Perspex, Altuglas .. are brand names

Acrylic or Acrylate is the short name for the plastics name : PMMA or polymethyl metacrylate

Good looking out.

[RodinUK]

It's the butane or propane flame gun that causes the crazing due to the stresses it induces.

Best to use a water/alcohol mix flame gun.

...but it's a GREAT antiquing effect!

What happen to that dudes hand????!!!
