Very low specific gravities on two commercial underglazes

AMACO and Crysanthos. 1.26 (67.5% water) and 1.22 (68% water)! The former is well below their recommended specific gravity of 1.4 (it still paints well but needs more coats, and more time to dry and apply them). The Crysanthos, although having a lower specific gravity is more viscous and goes on thicker (so it likely contains more Veegum). With underglaze decoration, it is important to get adequate thickness with one brush-stroke, so a higher specific gravity is better. This may be reason enough to consider making your own (by adding stain powders to a base and using NE Gasket Set 998249 Yamaha YFM 80 R Raptor 2005-2008 to gel the slurry, slow drying and harden well at the dried state).

Amaco underglazes can contain very high percentages of stain

Top are V-326 and V-388 underglazes, painted on and 04 bisque fired. Although the layer is very thin the coverage is amazing and the brightness is stunning. This degree of brilliance is not possible unless the percentage of stain is very high. That explains whey these are double or triple the cost of a typical commercial glaze. The bottom mugs are clear-glazed and 05 fired, the one on the left with Amaco LG-10 and the one of the right is Spectrum 700. The latter produces better results over the underglaze and is more transparent and less yellowish on the body.

Iron oxide as a fining agent to debubble a low fire transparent

These terra cotta clays were bisque fired at cone 04 and glaze fired to 04 using the 04DSDH schedule. The glaze is G1916Q, an expansion-adjustable cone 04 clear. That schedule alone is often enough to get transparent, defect free glazes in many situations. But not in this case. The solution was to add a fining agent. In this case we added 2% red iron oxide (to the top glaze). The particles of iron floating in the melt acted as a congregating points for NMC "Caution - Hearing Protection Required Beyond This Area", 10, helping them to escape. And we got a bonus: a more interesting aesthetic. A 1% addition also worked, but not as well (we have settled on 2% iron and screening the glazes to 100 mesh). Screening out the larger particles slightly degraded the fining performance (so we have to accept the tiny specks). Iron does not always workin other situations. Other fining agents we have used at cone 6 do not work in this situation (e.g. 2% Zircopax, Alumina). Of course, this glaze will fire amber on a white body.

Red stain in matte and glossy bases. Which looks best?

The silky matte. 11% Mason 6021 encapsulated stain has been added to each. The one on the left is G2926B glossy base (it also has 2% zircopax as a fining agent for the micro-bubbles). But in the matte base on the right, G2934Y, no zircopax is necessary. It produces a stunning surface using this and other stains (including orange, yellow, black, purple), very pleasant to touch.

G1916Q glaze fired at cone 03 and 04 on a terra cotta clay body

The body is Plainsman L215. Both were thinly applied and fired using the 04DSDH schedule. The glaze has 2% iron oxide added and sieved to 80 mesh, this reddens the color and acts as a fining agent to reduce micro-bubble population. The one fired to cone 03 (left) is considerably stronger, better surviving the stress of successive impacts with a hammer. However, it has minute dimples in the surface, likely because it is having to clear Bulldog Mini Range Nylon Water Resistant Bag w/Strap Black BD915 originating from decompositions occurring in the body below (as it fires well above bisque temperature). The mug on the right fired about 40F cooler, between cone 04 and 05, only slightly above bisque. The glaze surface is much better, almost crystal clear. Since the glaze fits well the mug has surprising strength, much better than a stoneware piece with a poorly fitted glaze that shatters with one tap of a hammer. This one survived about ten whacks before a piece broke out! A big advantage of cone 04 and cooler is that ware can be fired on stilts, meaning you can glaze the whole thing, no bare clay is exposed. Again, I can only achieve this kind of glaze surface using the above-mentioned firing schedule.

G1916Q transparent on terra cotta body at cone 06, 05, 03

The body is Plainsman L215. We used the 04DSDH firing schedule. The glaze is inexpensive to make so we have a 2 gallon bucket. It has good dipping much like a stoneware glaze so it is easy to apply quickly and evenly. For most terra cottas, body strength increases dramatically by cone 03. However the most transparent and glassy glaze surface happens at cone 06. Terra cotta bodies need to be bisque fired fairly low (e.g. cone 06) to have enough porosity to work well with dipping glazes. After cone 06 they generate increasing amounts of gases (as various particle species decompose within), for this reason the glazes can have more micro-bubble clouding or tiny dimples in the surface. This glaze has 2% iron oxide added as a fining agent to remove the Fujica Fuji Fujinon G690 Lens onto Sony E mount with close focus. That iron also reddens the color and variegates the surface somewhat. Even though the surface character at cone 03 is not a smooth, it has a natural charm, and the color is very rich. And that piece has stoneware durability and strength.

How to convert a dipping glaze to a brushing glaze

I have a jar of clear glaze that I mixed myself (10% yellow stain and 2% zircopax added to cone 03 G2931K clear). Commercial glaze producers make their lines of glazes like this. The cost of the dry materials: About $6. How can I make it paintable? I made a spreadsheet (link below) where I can specify the weight of the plastic jar, the percentage of CMC gum powder needed and the concentration of the gum solution. I just need to weigh the jar of glaze (without lid), weigh a teaspoon of the liquid glaze (lower left), dry it (upper right) and weigh the dry (lower right). After filling in these numbers the sheet tells me what weight to evaporate the jar to and how much gum solution to mix in. It paints on just like a commercial glaze. Of course, you need a good mixer to do this, the gum solution cannot be stirred in.

Making a QRCode using porcelain pixels

I 3D-printed a stamper to create 9mm square pixels. Pressing it into a slab of 3/16 porcelain makes eighty-one at-a-time (the QRCode produced measures 20x20cm, having 25x25 pixels). The black porcelain has 5% Mason 6666 stain. Firing temperature was cone 6. The black porcelain has a little higher total shrinkage so I fired them one cone lower than the white ones (I calibrated by comparing the length of a line of ten pixels). The pixels dry and shrink and drop out of the stamper easily. The action of the stamper rounds the upper corners of each. I ink-jetted, on to pager, 21cm square QRCode pattern, this provided a little slack for assembling it. Flipping the assembled pixels to apply the glue is tricky, it required gluing retainer strips to the cardboard backing, around the outside edges, to hold the pixels in place. For the next one I plan to glue the pixels to a zero-fired-shrinkage clay tile, made from L4410P. A little silicon sealant on the tile and that will be suitable outdoors. What does this QRCode say?

Context: Porcelain pixel QRCode is scannable. Try it!

Why you need to make your own glazes, fire your own kilns

Are you a potter that depends on glazes made by others? Do you have your ware fired in someone else's kiln? Cannot mix clay body tests? Then the evolution of the quality and aesthetics of your work is being stunted. This mug is a good example of why. This is G3933, version 1 of an oatmeal we made by adding iron, Horse Halter/Head Collar 1" PVC~Fully Adjustable~Available With and tin to a 75:25 blend of our base matte and glossy glazes. It is crawling at a few sharp angles of the incised decoration, that means it needs a little CMC gum. And, it is not quite matte enough, we need to switch to an 80:20 blend. Third, the red-burning body gives better color at cone 5, and this glaze melts well in a C5DHSC slow cool firing. So I will include it with other cone 5 bodies and glazes we are testing (because I want to move down from cone 6 to save energy and elements). Finally, I would like the glaze a little darker so I will test increases in the rutile and iron. All of these changes are on my radar because I make my own glazes and have my own test kiln.

You may know Veegum T but do you know VeeGum CER?

The glaze in this jar was 'goop', impossible to paint on because it was too viscous. And it dried way too fast. Laguna mentions adding water so I measured the specific gravity (SG): 1.7. That is super-high, it took a 125cc addition to bring it down to 1.5, but it was still thick, dried even faster and brushing it on evenly was even harder. It was not obvious what to do next. It needed a lot more water (1.3-1.35 SG is normal to support multi-layer application), adding CMC gum and enough water to do that would produce an unusable watery and sticky slurry. 2006-2008 Lexus RX400H Mark Levinson Speaker 6"x9" Foam Surround to the rescue! It is a 50:50 mix of CMC gum and Veegum T. The former slows drying and hardens, the latter gels. So it can simply be added until the painting properties are right. And, a Veegum CER solution is easier to handle than one of CMC gum. This really worked! The brushing properties are just right and it gels nicely on standing. CER is also good for highly fritted dipping glazes or others lacking in clay content (otherwise CMC might still be better).

What people have said about Digitalfire

  • I Everyday visit your website Fantastic knowledge you have....thanks .
  • After perusing your site for some time, I am really getting the sense of what a valuable resource it is. Thank you for it.
  • We have been aware of your company and website for many years and see it as a model in its approach to educating makers about the processes involved in making/drying/firing. You teach them to take responsibility for their work process rather than blaming the product.
  • We were at a friend's place whom had purchased the book "The Magic of Fire," and were both very impressed by the book - so I wrote down the web address and went to your site when we got home.
  • BTW, I do a lot of reading about glaze chemistry and find that Magic of Fire to be one of the most informative and straight-forward texts out there! Thank you!
  • I have found the glaze information on your site really helpful for quite some time now. I like the way that there is an emphasis on problem solving and understanding how things work, rather than just offering recipes that might work.
  • The Tony of digitalfire, wow. I love the digitalfires website, but I thought it cost money to get advice from you.

What people have said about Insight-Live

  • I have been following your Site and posts continually and gained a greater understanding. Thank you for that. It is so exciting to have a positive outcome from your glazes rather then the bought glazes. ... All good and exciting. My pottery clients are excited and have recognized the difference. There is nothing better than to pass on the best work possible to those who love the pots. So much work and testing, but well worth it. Thank you so much.
  • When it comes to new technology, I'm still thrilled with the chainsaw as apposed to an ax. I really do like glaze testing. You see a recipe in a book but it doesn't do you a lot of good until you can see it on a tile.
  • I'm a professional potter from Western Australia with a 30 year career - self taught. I came across Digitalfire when researching raw materials - an incredible resource you've put together!
  • I've really appreciated using your software.
  • I am a long time fan. I bought your downloadable book long ago and still refer to it frequently. Has bunches of my notes in it too. It expanded my college training with glaze chem. Appreciate you.
  • The knowledge and information you share on digital fire is a rare gem on the internet. I greatly appreciate your writing style. To the point and full of facts. I am wanting to be more active in my glaze creation and begin to make my own glazes. This, to me seems like a huge step away from the safe and what I know of the glazes I have been working with.
  • It’s been now a couple of weeks that I learn everyday with you and your amazing project. I find your way of tackling experiments clear, practical and smart. I wish more quality content like yours was available on all of my interest topics!, All Rights Reserved
