Title: Yellow experiments
Post by: Moira HFG on November 18, 2018, 03:36:54 PM
Hi All,

Recently I was trying to make some small (5 to 6mm) beads for a friend's project. She wanted a warm yellow colour, but not orange. And definitely not a cool or greenish yellow. Well, I found that every golden yellow I own went orange. Striking produces variations in colour but isn't very controllable at that small size.

I ended up working through all my yellows to see what I got. Here's my results (in case anyone else finds it useful!).

In each case A is worked as quickly and cool as possible, B is lightly struck, C is heavily struck. They are on 1mm mandrels.
Colours are:
1. A mystery rod (may be an old batch of Eff Yellow Pastel - that's what the rod looks like).
2. Effetre Yellow Pastel with Golden Rod enamel. (Nice texture but not yellow enough)
3. Effetre Yellow Pastel (stable colour but definitely orange)
4. Effetre Yellow Ochre (interesting colour, unlike the rod. Orange with a hint of green!)
5. Effetre Light Zucca (went warm orange then struck back to yellow in patches. More yellow than the pic shows.)
6. Effetre Apricot Yellow (as Lt Zucca but less yellow)
7. Bullseye Marigold and Sunflower frit on clear (grasping at straws here!)
8. Unknown stringer, maybe Effetre Light Lemon (no stone unturned. Heavy striking produced some surprising semi-translucence.)

I was aiming for the colour in 1B. I made some more but it wasn't very reproducable, around half were orange.
If anyone can recommend a colour for future use, I'll get some next time I put an order in. I'd prefer 104, but would consider 96.

Thanks, Moira

Interesting stuff. Thanks for sharing. I like CiM Schoolbus - I think they describe it as orange but I've always found it to be a nice, warm golden sort of yellow. Eff Med Lemon (408) is usually my go-to yellow. CiM Pumpkin and Goldenrod are also nice (but sometimes hit and miss over whether they're available)
I'll post a pic if I can remember my flikr password 🙄

Schoolbus! I'd forgotten that existed. Does it look like the rod when worked? i haven't seen the other CiMs you mention.
I'd love to see pics if you can batter your way back into Flickr!
Thanks for the advice! :)

Sweeping little dust, but... my 2c

If you need a specific color in between two others consider mixing them. The number three is too reddish and sulfur yellow not reddish enough they should mix to the right hue. For a quick experiment start with the ropds and mix the first two centimeters of both. Once the striations are small enough pinch a small part with the tweezers and wait untill it is cold enough for the true color. Too ...ish, add the other color.

For the reddish part you can take every color that is red, orange or coral. For the other part you can take every too yellowish color and ivoury (???). Ivoury turns every red into more yellowish hues. If the color needs to be slightly more muted add little brown oe traces of cobalt blue or pea green. The last two additives heve to be tested with yellow or an other sulfur color to be really free of copper (no black lines between both colors when melted on top)


The maximum usefull batch size is 5 gramm for a "single fuel torch" and 20 gramm for a propane oxy torch. 20 gramm filles a round film container.

If you need more than one big batch measure the components and repeat the measuruing for every repeated mixture.
