scum free transparent green?

Sarah9959 · May 28, 2012, 09:53:13 AM

Hi, wondered if anyone could recommend a scum free transparent green. I have effetre light green and olive, and love the colours but they always scum for me, any recommendations?

I am particularly looking for a paler, yellowish green.

Thanks

Sarah

I love CIM mohito. Slight acidic.

Can you work a little cooler to stop the others scumming?

Effetre Light Emerald. I used it this weekend and it's a lovely shade

To stop glass from scumming, you can temporarily slightly turn down the oxygen at your torch. I do that a lot when melting aqua for example.

Transparent yellow green, light grass green, CIM appletini. I have problems with the effetre transparent line green too.

Definatley Pale Emerald and Mojito - they are gorgeous - never had a scumming problem with any of them though, so might be gas mix...

Being new to the forum and being self taught, what do you actually class as scumming and how does it manifest itelf?

My current batch of grass green is seeded, you can see the damn air bubbles all the way up most of the rods.

I also work the limes/aquas in a slightly reducing lame (less oxygen) to try not to boil it.

Many thanks, will give some of the suggestions a go when puting in my order with Martin.

Could be temperature, but then again I don't get the same problem with the blues I use, but will try reducing the heat - maybe green is rather sensitive!

Nete, scumming is when the glass produces hundreds, maybe thousands of tiny bubbles, so small they do not look attractive but rob the glass of its clarity.

Thanks again

Thanks for that Sarah. It's useful when you understand what these things mean when you are looking to resolve problems on this forum. I've had lots of problems with grotty brown lines and marks and I that might be called "scumming". Now I know its not.
Cheers

You can avoid the brown lines by again using an oxidising flame and not too near the torch.

I usually turn the oxygen up with the delicate greens

I use CIM Oz (A beautiful emerald green) - Never had a scumming issue with this one and martin has it in stock.
If used over clear it is less dense, but still not a light green unfortunatly.

Many thanks James, will give it a go at next order, and use it over lighter colour (maybe yellow?) to try lightening it up.

Are you pulling the ends of the rods? I find that helps...

(I LOVE Olive green....

I'd suggest turning down the heat a little, or working further back or to the sides of the flame and making sure you're working in a neutral flame. The only problem I've experienced with scumming has been working with dichroic glass.
