37. Rubbing Ink into the Crackle Glaze to Enhance the Pattern with Hsin-Chuen Lin

[Animalover4231]

May i ask what glaze did you use or could you please post the recipe

[hellophiney]

lovely! you're a great artist. if i was going to do this to a teapot would i have to use a normal glaze on the inside?

[ameichholz]

Does the food safe stain (colorant) wash away?

[matiasisa18]

Hi Hsin-Chuen, great videos, ive learne alot from watching them. I really love this crackle glaze, but i see that is fired at cone 10, all we do at my school is cone 6, what can i use to get something similar at a cone 6?

thank you

[hsinchuen]

@matiasisa18 Hi, the crackle is cause by different expansion and shrinkage rate of your clay body and glaze. Sometimes by just changing clay body you can avoid or create the crackle. Do some experiment on applying one shiny glaze  to different clay bodies. If not, then tell me the recipe, I might be able to modify the recipe to achieve the effect.

You are one of the few really good potters I've seen on You Tube.!!!

[gothampixel]

What was the glaze used here and how was it fired?

[hsinchuen]

@gothampixel Iceberg for crackle. Red Iron stain for texture part. Some cone 10 reduction and some oxidation.

Thank you for the demonstration. So beautiful. The food color is a great idea. I have used India ink. I tried a chinese crackle glaze recently in reduction and it didn't craze. It was from John Britt's glaze book. Any ideas?

Thanks!

[hsinchuen]

@clayphoenix Do you have the recipe?

[zhpottery]

@hsinchuen i have the same book, the recipe is this:

chinese crackle

custer feldspar 83%

silica 8%

whiting 9%

----------

zircopax 10%

[hsinchuen]

@zhpottery My suggestion: 1. replace custer spar with Kona F-4 spar. 2. replace 10% Zircopax with 5% Tin Ox + 5% Zircopax. (I know Tin OX. is more expense than Zircopax) 3. use different clay body.

Do #1 first to see if it work.

[lpparanoia]

Is that a stain or a glaze on the chattered portion of the cups?

[hsinchuen]

@lpparanoia Red Iron stain

[credenza1]

Beautiful. Nice to hear you speaking on your clip.

[zhpottery]

how many different types of porcelain have you worked with and which do you prefer to use?

[hsinchuen]

@zhpottery I used the mix of Coleman and Glacia porcelain (from local supply) about 50/50. That's the only porcelain I used.

[SharJoyC]

Just love your work! These are stunning!

[ThatLynnGirl]

Wonderful!!! Thank you!!!

Over time does the food coloring ink fade?

[hsinchuen]

@31361claire Yes, if you keep on washing it.
