I'm based in Germany and can't find the L 407 Heraeus overcoat anywhere (odd as seems they are a german company) - does anyone know where I can order it or if they've stopped production? What is the overcoat made of? Thinking of making my own at this point - perhaps some kind of gum
I love your video but am in the US - do you know where I can purchase the Heraeus products you are using (oil and covercoat?) I don't mind getting overseas as well. Thank you!
Kathy I make decals and fire them in a kiln there are several suppliers in Australia but the one I use is Elliot ,Fay & Paul Good ( Interdec Australia Pty Ltd 53 Galway Avenue Marleston SA 5033 Phone 061 08 83714100 or fax 0883714142 I don't know if they have a website , they supply the duplex paper , ceramic glazes , glass glazes , medium oils to mix with the glazes and cover coat . the duplex paper is 200gram weight paper that has glue in one side after you print on the paper and over coat you cut out your print and stick the print into a bowl of water that melts the glue and releases the transfer . I found buying the glazes in powder form and oil medium separate then mixing them as I need them is the best way , you can buy it premixed but after storage in a bottle the glazes go hard and you need a special machine to rejuvenate it , I use a spatula and a tile to mix my glazes making sure there are no lumps in mix as it will cut your screen as you drag your squeegee across. The cover coat is like a varnish and it is used to hold your printed images together after you have released it in the water otherwise the images would separate ( ie - a name or text would separate to individual letters ) I print my print on the paper pin the dried sheets on a board and spray the cover-coat over the sheets with small spray-gun it dries almost instantly the ceramic glazes fire at 750 deg C and the glass glazes fire at around 480deg C I don't make multi colour prints as you need to make a separate screen for each colour instead I choose to hand paint my colours and refire my ceramics , that can be refired as many times as you like , The cover coat burns off at about 300deg C and doesn't leave any residue or marks I sometimes thin my cover-coat with thinners to spray and sometimes use turps in my glazes to thin ( not much) the glaze dries very quick when you try to screen it and sometimes you need to clean your screen to get a good print image
thank you the video. Could his be done for glass decals? do you need different ink? mind you I know nothing about screen printing. I'm a glassblower and would like to make my own glass decals. Thanks
Danny Mumbles yes you need change the ink, actually it is glass color power and you need mix with flux oil before print. sorry I don't know exactly how to tell you the name of materials because of my pool English.
I'm - Bjarne Nielsen - who made this video and these decals, I think it's best that I'm also the one who answer questions about how I do it. Terry Lazaroff As I said in the video, I fire both the first glaze firering and the second with decals at the same temperature and in the same kiln. I have tried to fire at 850 degrees Celsius, but then you can see a shadow after the covercoat in the glaze. Danny Mumbles: I have never made decals on glass. But a friend og mine is a glassblower, and I know he has made decals with same sort of stains. MsMonanna: My silkscreen is a yellow one, 100 mesh.
i think the point here if to make artisan product not factory made product. Yes I'm sure your factory in China can made a ton of cheap decals that are great for ceramic factories and cheesy corporate coffee cups. But some people still make handmade and the people wanting to buy handmade don't want factory decals.
