Turquoise going murky red?

[elburnzo]

Another newbie question from me! I made a set of beads from dark turquoise effetre trans, first few were fine in colour but cracked. Next lot have swirls of red/brown in them! Not sure what i've done wrong here. I'm on a hot head.

The red brown marks are from where the glass has got reduced slightly, which is easily done if you work a little too low in the flame on a hot head, try moving a little further out and work a little cooler

top advice!

Hot Heads naturally have a slight reducing flame - but working further out there is more oxygen and it's a little cooler. It might take you a little longer but it will help. Not all colours have this issue, but turquoise does for sure!

ah! thanks I'll give that a bash tonight, i must've moved further down the flame without realising it. 

Which is interesting as i cant manage to reduce things intentionally lol

I have some light blue which does exactly the same thing and I'm on an oxy set up.  It's definitely not a turquise blue either.  Yet when I etched the bead it disappeared! Huh?  How did that happen?

Exactly the same as the turquoise.  You get it with Sky Blue and Periwinkle, and it does go with etching - or coke, or cilit bang!

coke you say...... I have a bottle! Maybe I can partially save some of the beads then before i make more. Makes you wonder why Coke isnt considered dangerous though!

Coke?  Liquid or powder?   

Only joking  - will Diet Coke do it?

Can't say I've ever tried the powdered type. Most people say not diet, full fat only, but its worth a go - oh and it can be flat too.  Just leave it overnight or a bit longer and it should do the trick.  I usually just etch though - having said that, any bead that stays in one place too long gets etched!

[elburnzo]

think the powdered version would prob be more expensive than the etching solution lol

I only have diet caffiene free stuff! barely cola at all but ill whack them in tht when i get home. wonder if my mum has cillit bang!

i think ill keep the bead filled cola in the shed in case the boyfriend drinks it!

Makes you wonder about coke - when it does the same stuff as Cillit Bang

We used to clean dirty pennies by leaving them in Coke
