Glass Casting - using the 'open mould' method with Di Tocker

- Casting glass using an 'open cast' mould. I'll show you the process I used to create this cast glass object for clients in June 2020. Gain an insight into the many steps to create a cast glass art object - working with wax, making a kiln mould, glass selection and packing the mould, firing the kiln, divesting the glass from the mould, grinding and finally polishing the lead crystal sculpture.
Join me in my glass studio in Cambridge, New Zealand as I take you through the process on creating a commission such as 'Teale Odyssey'. I would love to hear from you if you have any comments or questions about the process of casting glass. Please add to the comments section and subscribe if you would like to see more.

loved the work and one upside to this method is you dont have to worry about snags and this open cast has restored the desire to resume my geometrical glass projects.
Owww excited to see what comes of!!!!!!

Thank you!
that's beautiful piece, I wish I had a kiln...
Thank you.
have you ever tried making glass rings? great work
Congratulations
😊
That is beautiful work. What plaster do you use? Can it just be regular arts and crafts plaster?
I use Victor brand plasters, same for the building industry
Absolutely amazing how many hours do you think that piece takes from mold to finish
That's so hard to say as I work on quite a few pieces at a time. Perhaps 20-30 hours on this one 🤔
Thank you for sharing this video. I am totally new to this stuff. May I ask what the white mud is that you used to make the mold to cast the glass with?
The (white mud):mould material is plaster and silica
Hi!! Amazingggg work! I’m having trouble taking off the plaster from the glass. There is still a thin layer on top of my glass figure. Do you know what can I do in this case?? I’ve tried sanding the piece and still won’t come off. Many thankss!!
👏👏👏👏
Wow gorgeous work Di
May i ask which wax you use? I'm from NZ too
Hi James. I use a blend of micro crystalline waxes. I like dark wax as I can see the form better when smoothing etc. But its hard to get now. Techniwax 20001 (I think) from Allied Petroleum is a good base but you have to buy 20kg or so.
Donde puedo comprar los materiales y herramientas que usaste para pulir y para hacer el molde?
Hello, thanks for thus vidéo. I'd bé so gratefull if you could precise tour firing schedule : how long to reach 850°C ? Wich température do you reach then and how long do you stand It ?
What temperature did you fire it at, and was that the full 5 days at full temperature? If you were using one colour of glass would a day or so have done? Did you have to ramp down the temperature, or could you leave it in the kiln to lose heat naturally as the kiln cooled? Can you reuse the wax after steaming it out? Amazing video, thanks for sharing!
Ok there's lots of questions. I can only answer for the work I do. I fire this work at 850 degreesC. The colours do nor make a difference to how long. The glass must cool slowly. I have electronic 8 stage controllers on my kilns.
Yes, you can re-use the wax.
What is the required temperature?
I'm blown away at how well that plaster held up to 850C. Are you using sodalime glass?
No, soda lime glass would not pour into all the detail. I'm used lead crystal. The mould mix is plaster and silica. Without silica the mould would not stand up to high Temps.
Thank you for informative video! could you tell me how you steamed the wax out? or what tool the steamer is please?
I use a wallpaper steamer. These work very well
@@ditockerglass4790 Thank you! Also I am learning and preparing to try all this from knowing not a thing... and I am wondering if you could tell me what the radial sander you use is and the grits? Is that an item sourced from Hardware stores or is it a specialty glass working tool? If that's not too elaborate a question? You probably use a tried and true sander...
Is it possible to cast a very simple form in a reusable rubber or silicone mold ?
You need a mould made from refractory materials such as plaster and silica
The mold material is ready made or mix it yourself? do you mind specifying the mold recipe?
I mix the mould materials. The base point for using plaster/silica for moulding is 1/3 water 1/3 plaster 1/3 silica. I have variations from this base recipe to allow for strength, expansion etc
I want this, but how any available store at online??
Thank you fof youd interest! Please visit www.ditocker.nz
What materials do you use for your mould, and what is your firing range?... temperature
Plaster and silica for the mould. Grog is added to the outer layers for strength. I fire this to 845 degreesC
That kiln probably cost what a house does wow
How do you determine how much glass to use?
There is a formula wax weight to glass weight. Each brand of glass calculates different
What materials do you use to make the mold? Is it plaster?
The mould material is plaster and silica mixed with water
What type of plaster silicar
@@agrippanyagwaya2308 I use 200 or 350 grade silica.
Why not flame polish it?
It's too risky for the thickness of glass.
what kind of wax do you use
Hi Marina. I can't tell you exactly because the wax o is is so old now. 20 years ago my fav was a 'victory brown' but I don't think you can get that now. I like a micro- crystalline wax with a depth of colour to see facets and blemishes, a wax that is a balance between hard and soft, that I can melt, pour, carve, join and that works well in winter cold and summer heat.
@@ditockerglass4790 thank you very much for you answer. your works are very beutiful. thank you that you share your workprocess with us.
How much would this piece sell for?
This was sold for NZ$5000
what is the composition of mould?
Plaster and silica on the inner layers, and grog for strength on the outer layers.
Bonjour, je fais un travail sur les matières, et dans ce cas c'est à mon tour le verre et bien, parmi beaucoup d'artistes j'ai choisi ce travail, (si cela ne vous concerne pas) pour mon travail de clade. Cependant, je ne trouve pas beaucoup d'informations à ce sujet. Pourriez-vous m'expliquer un peu le travail et que l'on vous implorait surtout de le faire.
Vous m'aideriez beaucoup, merci.
Hello, I am doing a work on materials, and in this case it is my turn to glass and well, among many artists I have chosen this work, (if it does not matter to you) for my clade work. However I do not find much information about it. Would you mind explaining the work to me a bit and that you were implored above all to do it.
You would help me a lot, thank you.
It's exciting that you are interested in glass. If you wish to find out more about my work please view my website www.ditocker.nz of Facebook and Instagram both Di Tocker Glass
Might want to wear a mask to prevent breathing glass dust.
I take all necessary safety precautions
Can you please assist me with tutorials on casting memorial tombstones,I'm in Zimbabwe .... kindly regards Agrippa
I wish you well with your castings but sorry I am not able to give tutorials. There are so so many variables to working in Glass, it is best to find and learn in a workshop. Good luck!
Your so inspiring I love this vid!! Your work is amazing! Do you mind if I give you a shout out if I eva upload my own glass making vid to youtube?
Do you teach ?
I did teach for many years but not anymore as I'm concentrating on making
YOU CAN'T JUST DO A VOICE OVER WHILE PEOPLE IN THE SHOT ARE TALKING WITHOUT DROPPING OUT THE SOUND
That was one of my fav parts of the vid, I thought the voice was epic
