Slumping Over Chalk -- Easy Fused Glass Project

[@kathrynvanvliet5214]

Thanks for this! I love that no separator is required for slumping over chalk. No ZYP, no thinfire, nothing! I like to slump green stringers over chalk for curvy flower stems. Love your videos!

[@StephFuses]

I love the green stringer idea! My cousin and I are doing orange right now, for pumpkin lines

[@AnnetteRintelmann]

Love that you show a learning with something new. Thank YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@StephFuses]

Thank you! Not everyone has access to the fancy slumping stuff, and chalk's cheap, so why not use it?

[@3PairDesigns]

Excellent info Steph! Very useful, thank you so much!❣

[@StephFuses]

Thanks for the comment!

Thanks for sharing as you experiment!

[@Jonathan-fz8di]

Thanks for sharing your experiment, interesting...

[@StephFuses]

I figure not everyone wants to spend a lot of money on slumping forms for wavy pieces for one project, but a box or pack of chalk is cheap. So why not see what it does? I've used it 2-3 more times, and it's still holding up in the kiln.

[@glassjackbuls]

Good to know all your test results thanks

[@StephFuses]

And I've used it 2-3 more times in the kiln, and the chalk is still holding up!

[@RampRateArt]

Good test! Going higher or holding longer will definitely help with getting more dimension…

I did some for Halloween, and used 1240 and it was much better

[@dianacrick5089]

Thank you for this. You answered my questions perfectly, and as you said, very little info exists. I want to shape stringers to break them up to represent stems with a curve. I thought I might have to wrap the chalk with kiln paper. I am glad I don't have to.

[@StephFuses]

I'm glad I could be of use! I want sure if I could share the link in the group or I would have done it directly. I find 1240 gives wider waves, and a spent kiln shelf won't let glass stick at that temp. You could throw this fire or papyrus down just in case though

[@dianacrick5089]

@@StephFuses Do you go fast up and fast down to 700° and then kiln off?

[@StephFuses]

Usually I do about 600 up to top temp, and then off. and leave them be until they're under 200@@dianacrick5089

[@susanhardy1443]

Thx Steph!! Can you use the chalk multiple times or one and done? If multiple times, any idea about how many times?

[@StephFuses]

I've used the chalk 3 times so far and been fine. I do know eventually it will crumble, but it depends on the heat you're taking it to, how you treat it, how humid your workspace is, etc.

[@chrisliegandt9111]

Steph I am trying to slump over chalk. I notice fumes coming from the microwave. Did you experience this?

[@StephFuses]

Is your chalk coloured? It could be the binders keeping the chalk together burning off

[@AnnetteRintelmann]

Steph what temp did you use to slump the stringers?

[@StephFuses]

gentle wave: 1225. Better wave: 1240
