Color line Paint and ...

Postby cwb-bdb » Sun Dec 10, 2017 2:06 pm

First allow me to thank you for your patients and putting up with my endless questions.
Let me start by saying this is a fully fused piece.
It was fired to:
Rate Temp. Hold
400 1225 1:00
600 1425 :01
Full 900 2:00
60 800 :10
80 600 00:00
If I now wanted to apply a small amount of (Color Line Paint) what would be to lowest temp. I should take the piece up to in order for the Paint to cure and affix it's self to the glass.

My fear is that I will some how affect the already finished piece and ruin what I have accomplished thus far.
As this is hopefully going to be a Christmas gift, time is of the essence, (I know I should have thought of that and started earlier).
So that said if you could suggest a firing schedule you think will work, it would be most appreciated. Also if in your learned opinion I should not try this action, please let me know.

Again, let me thank you for all your help.

We need more information. What color of Color Line paint? What styles of glass did you use? How large and how thick is the piece? Is the surface smooth, or does it have relief (as in tack-firing) or texture? Do you have a photo?

Also, what cycle would you propose for this next firing? We can give you feedback on your best guess, and you will learn more than if we just propose a cycle.

You might find the Color Line Paints website helpful: http://colorlinepaints.com/paint-techniques/#

Looking forward to hearing from you!

This is the same piece as described in my Nov. 17th question.
5'X5"
Tekta #1100 caped by White #113 with some floral design on top of the #113

I now just need to add a very little (Color Line Paint) Green #112 to an area where I need to fill in a space that the glass floral design did not cover. I would say no more than 3mm long by 2mm wide.

My purposed schedule is:

350 1200 00:00
Full 1360 00:05
Full 900 00:30
50 700 00:00
Thank you

Thanks!

So, this was the last firing that we recommended. Is this the schedule you followed for the last firing before applying the Color Line Paints?

270 to 1425 hold :10
Full to 900 hold 3:00
45 to 800 No hold 00:00
81 to 700 " " " "
270 to 70 " " " "

Your proposed cycle should be based on this previous cycle.

The cycle that you are proposing looks too fast on the ramp up, too little time at 900, and and the ramp down should have two stages, like the previous cycle.

The piece was tack fused first.
Then some powder was added and a mix of Aloe Vera and powder was used to create stems on the leaf.
Set aside to fully dry.
Then Full fuse To:
400 1225 1:00
600 1425 :01
Full 900 2:00
60 800 :10
80 600 00:00
Now I want to add the Color Line paint about 3mm long and 1mm wide. The issue is what to fire the paint to, and not change the piece. Just add a little color where it is needed.

Thanks, sorry for being such a problem child.

From the Color Line Paints instructions:

Recommended firing temperatures are 700°C to 820°C (1310°F – 1500°F). Fires glossy from 740°C (1365°F) onwards.
Up to 650°C (1200°F) keep the kiln ventilated to allow the medium to exhaust. This is especially important for the
red colours (more info see section “Lab Notes”). When using the paint between layers, fire the individual layers first
separately. Stack or combine the components for a subsequent firing


If you want the green to be glossy, fire it to 1365 degrees F. However, this may partially or completely flatten the relief (tack fired) effect, depending on whether or not your kiln tends to "run hot" or not. Only testing will tell. If you put a lot of time and materials in this piece, run a small glass test with a similar arrangement/heat history/glass styles.
