SORRY SWIZZLE, SOMETIMES BAD THINGS HAPPEN TO WONDERFUL TIKIS. I REALLY LIKE THE CRACKED GLAZES BUT ON MY TESTS THEY WERE MEDIOCRE. YOURS LOOKED REALLY GOOD.

WHEN MY GLAZE HAS BEEN TOO THICK AT THE BOTTOM OF A MUG OR BOWL IT HAS BOILED AND ENDED UP PITTED LIKE LAVA. I'VE NOT HAD IT CAUSE A CRACK SO FAR. I LOOK FORWARD TO READING WHAT OTHERS HAVE TO SAY.

BEST OF LUCK ON THE NEXT BATCH, WENDY

Thanks Wendy. That crackle effect is not actually a feature of that particular glaze. I think it just happened as the mug was cracking. The other mug was fine until I reglazed it and that one did it then also (see below).

This week I picked up a few more of my mugs which will be going to friends and really are just for me to experiment with colours and to get my head around glazing.

This first mug will stay in my collection as it's the first mug poured from the new mold I made after I resculpted the master. It also has additional woodgrain carved into. Initially I tried to use a brown oxide on this mug which was to be applied and then wiped back to leave the colour in all the crevices, but I wasn't happy with how it turned out so I glazed over it with the brown used on the inside of the mug. After it had been fired I felt the finish was too patchy so I glazed over it again, this time with a lead based glazed called "Crackle Goldene" which should have come out literally a dark gold like colour, but it didn't. I'm still quite happy with the result though.



This mug is going to one of my oldest and dearest friends. This mug was also reglazed as the finish was too patchy for my liking. Although it still is a little bit, it certainly looks much better. Royal Blue exterior with Oyster White Speckle interior.



This mug has gone to a good friend who is the brand ambassador for Appletons Estate rum here in Melbourne, Aus. Although it had three coats of glaze on it, it still came out patchy (like the others) where the bush strokes are noticable. He, and another friend who saw it both like the finish and both said the same thing, it makes the mug look handmade, which I take as a compliment. This is the closest colour we had at school to red (his favourite colour) without using a lead based glaze. Burgendy exterior with Mist Green interior.



This last mug is another that I reglazed as I wasn't happy with the result, although that was more so because it didn't seem to come out the same colour as the mug I had glazed a few weeks earlier that cracked (page 4). Peacock Green exterior with Apple Green interior.



However, guess what happened?



That's two mugs that have cracked using the same green glaze. Originally I thought that the first mug cracked because the glaze on the inside was quite thick but this mug had only one coat on the inside and the same thing happened, although not as bad, yet it is still unusable. It was fine after the first glaze firing and only did this after I gave it another couple of coats, a total of four. I spoke to one of the other teachers at school and they said another student had made a huge vase and glazed it with the same colour and that cracked also. I rang the manufacturer and explained the situation and they said that they had never had any problems with that glaze before and that it must have been the clay body I was using, however that doesn't explain the other students vase which would have definitely been a different clay. They also said that there must also be some sort of tension issue going on with that glaze and the others used on the interior (a different brand) and that I should try using just that glaze on its own, but thats quite useless to me if I want to make a two-tone coloured mug. I'm really quite pissed off as it's a beautiful colour and I have two mugs to make for people who both want green but i'm reluctant to use it again as I don't want to waste my time if this is going to happen again. We have an Italian Green at school which is slightly darker and a different shade, but still quite nice so I think i'll give that a go instead. Fingers crossed that will be OK.

That's all at the moment. I have glazed another two mugs which are ready to be fired. Hopefully they'll be ready next week.

Cheers
swizzle

HI SWIZZLE, I JUST READ YOUR THREAD. I BROKE MY ARM AND HAD SURGERY SO I'VE NOT KEPT UP WITH ALL MY TIKI BUDDIES AS I SHOULD. SO SORRY THAT YOU ARE HAVING PROBLEMS WITH CRACKING. I HAVE HAD A LIME GREEN GLAZE THAT JUST FALLS OFF. I HAD TO TOSS A MUG. I DID TRY TO RE-GLAZE IT AND MORE JUST FELL OFF. IT WAS THE GLAZE BECAUSE ALL OTHER 33 MUGS CAME OUT FINE.

IT DIDN'T DO IT WITH MY GLAZE TEST THAT WOULD HAVE BEEN HELPFUL. YOUR MUG IS TERRIFIC IN EVERY COLOR, CONGRATULATIONS.

HUGS, WENDY

Thanks Wendy. When you mentioned that i went back and had a look and we were writing at the EXACT same time. How bizarre is that?

Picked up another glazed mug from school this week that is going to a good friend. He specifically asked for brown with red on the inside and the only nice red available at school to use is lead based, so he won't be drinking from this one.



When i picked it up from school and was having a look at it i noticed it had already had a few crazing lines on it. Yesterday when i woke up i turned the heater on, as it was a very cold night here, and i could hear the tell tale sounds of pinging coming from the mug. I went out out for a few hours and when i got back i heard a few more and had another close look at it and was amazed at how many more crazing lines now covered the mug. I've heard another one or two today also. The crazing doesn't bother me, i actually think it adds character to the mug, i just hope that it won't actually crack.

P.S. The reason it's so dark in the teeth and around all the raised sections is because i put some black glaze there and then wiped it back so that it would show through underneath the brown. Came out exactly how i wanted and i'm very happy with the finish.

Looks great Swizz! Because a mug can last forever and so does lead, I like to write "NOT FOOD SAFE" on the bottom when appropriate. This guy's great grandchildren could end up with lead poisoning when they discover this mug in the attic 100 years from now and use it to drink from

You are sure having your share of trouble with glazes, don't get discouraged! Everyone else has put their 2 cents worth in, I might as well add mine: Are you using a cone pack to be sure the kiln isn't over or under firing? Are you able to try a slower cycle so the kiln has more warm up and cool down time? Could be a
Glaze Fit problem Are other people in the class using the same clay/glaze combination? Are they having problems too? I was told I could use low fire glazes on a high fire clay body fired at low fire - but I got shivering (chunks of glaze coming off) every time I tried it. I realize you may be limited in your choice of products, either in the school or available in Australia, but you might want to try another slip or glaze. The other (much more complicated) option is to put additives in your slip or glaze, I'm afraid I don't know much about that but the information is out there.

Keep pluggin' on Swizzle, you'll find the right combination!

Thank you so much for your input MDM, it's much appreciated.

Your advice on marking the mug not food safe makes sense. I just went and wrote that on the bottom after reading your comment.

Unfortunately being a community kiln i have no control over the firing. I go to each weekly class, glaze a mug or two, leave it there and hope it's been fired and comes out OK the following week when i'm there. My biggest issue has been with the green glaze, and the crazing on the recent brown mug i think has more to do with temperature fluctuations. Melbourne winters are quite crazy. Cold at night and then quite pleasant during the day. The slip i've been using has been fine for all the other mugs i've glazed so i'm not sure what's going on. I think it is the combinations of glazes i'm using. The interior and exterior glazes might be the same brand but there is obviously an issue with them reacting to one another after they've been fired. A tension issue i believe it is.

I'm very new to this and have learnt, as i've been told and read, that this is not an exact science and you cannot guarantee the outcome that you are hoping for will work. It's just frustrating spending so much time making and glazing a mug to have these things happen.

Thanks again for your comment.

Community kilns are a problems, I lost a few pieces that way. I've lost a few pieces in my own kiln too, but I had no one else to blame it on!

Thanks Wendy.

I only used the lead based glaze because red was requested, Beachbumz. I personally don't like red myself so i wont be using it again. However.....

I picked up another two mugs today and this first one has the same lead based red glaze. The friend this mug was going to wanted it in his football (Australian Rules) teams colours, which are red and black. He wanted the mug red on the inside and black on the outside with the red flowing over the top like lava. I was happy to try that effect but as he really wanted to drink out of the mug i told him i'd have to do it in the reverse so he could use it. I glazed the red within an inch from the top and then added the black drips. Unfortunately the red didn't work quite as i had hoped (see the brown mug with red inside above) and my teacher said that this particular glaze could behave strangely during firing depending on number of coats and heat of the kiln, but i think it came out great. It has ended up with a very unusual finish.





Although all my mugs so far have gone to friends and have been test vehicles for me to practice glazing and with different colours, this mug was a true experiment. When it was poured it was using the last of my slip and it didnt fill the spare so i had to keep tipping the mold over and pouring slip around the top. Although the mug ended up its full size it ended up very thin at the top. For that reason i decided to keep it for myself to play with and i added some clay to make his nose bigger (compare with above) and also some Fu Manchu style bits to his beard/goatee. I also played around with the glazing. Initially i had painted the eyebrows and goatee black ang glazed the blue over the top hoping that the black would show through. ( The teeth and eyes were done in white as you can tell.) When it was fired the black didn't work how i wanted at all so i reglazed it again, and touched up a few other areas at the same time, and had it refired. This is how it came out.




I have to say i dont love it, the blue is very patchy and has bled into the white and there are a few places it has actually gone a green metallic colour, but the marbling effect that occured with the black after being refired is quite interesting and given me something to play around with on some other test glazes.

During the week i also bought some powdered glaze i mixed with water myself so i can practise dip glazing. I'm hoping that, besides being quicker than brushing it on it will also give me a far more even and consistant finish, which is what i'm really after. The colour at the front is Italian Blue and it is the dip glaze. It is also a crackle effect glaze. The green at the back is a brush on glaze called Italian Green that i dipped also just to see how that worked in comparison. When i dipped the blue you could see it left a coating on my test piece with a noticable edge, (You should really be able to see that in the pictures) whereas the green appeared to soak in. It was actually really interesting. You can see the edge in the second pic also. The #1 signifies it was dipped once and the #2 twice.



I'm looking forward to seeing how these come out and will post pics when i have them.

Love the Fu Manchu The red is indeed interesting, you probably couldn't do that again if you tried!

Hi Swizzle, I've not yet dipped but I did the Zombie Hut with a spray gun. It worked really well especially with three layers. I still poured the inside of the mug with glaze and drained out the excess.

When you do dipping you can also use wax resist. Paint the areas you want to use another color on. Dip, fire. The wax burns off. Paint those areas with your next color and fire again.

You are just like me doing all sorts of tests. If fun when you find something that you really like. I'm enjoying your journey, Wendy

Robbie, hope you don't mind BUT I had to post some pictures of the mug I received in the mail today, It's Awesome Brada!



I think the blue coming over the edge is an awesome look, I'm going to try and do a few like that next time..
Mahalo again!

MDM, you're laughing at the Fu Man Chu so i'm not sure what you mean by that , but i agree with you that i'm sure i couldn't get that effect with red again if i tried.

Wendy, i'll be looking into the wax resist and below you will see my first test results with dipping. They generally say it's about the journey, not the destination, but i think with ceramics that might be a little bit different.

Scott, of course not. I have to steal them because i cant find the ones i took of it myself. So happy that YOU are happy with it. That blue coming over the edge was not intentional, but i have to say i do like it myself.

So anyway, i only picked up one glazed mug this week as i was busy doing other things so that was all i had time for, and guess what...............................................


it cracked.

This is the second mug to crack that is/will be going to someone in the U.S. (you'll find out later if i ever get it right ) who asked for black on the inside and green on the outside. After the first mug shattered in the kiln and another using the same green -see previous posts- cracked, i decided to try another colour green. (I'll explain that below).



If anyone persists with this, thank you, because this will be a rant.
The first mug that cracked/shattered was glazed with (Cesco)Gloss Black on the inside with (Northcote Pottery)Peacock Green on the the outside. The second mug was glazed with (Cesco)Apple on the inside with the same (Northcote Pottery)Peacock Green on the outside. (Although this mug didn't crack after the first fire, it did not have the same colour as the first mug and was glazed again and then only cracked after the second fire. -See my previous posts to understand the colour difference-). After being glazed again it still didn't end up with the same colour.

This latest mug to crack was glazed with the same (Cesco)Gloss black on the inside with Italian Green(again, Northcote Pottery) on the outside. Both the peacock and italian greens are NOT supposed to be crackles (see below) yet both did that.

After having a look at all the mugs that cracked i noticed they all cracked in nearly the exact same spot, along the line (on the same side) of where the mold seperates. I understand that there might be a weak spot there but that doesn't explain why, of the thirteen mugs i have glazed so far, the three that have cracked were all green and all from the same supplier/manufacturer, yet every other mug has been fine. (The one mug i thought would crack had the same Gloss Black on the inside and was also fired TWICE).

I like the colour green and want to make some green mugs, but this is quite frustrating. If any mug makers could give me some feedback on their opinion on what might be going on, i'd appreciate it.

So anyway, if you're still with me, i glazed three more mugs this week, (one for a friend in green-but two completely different greens (both the same brand), another for a friend, just a test-he wants red and black- and i also did my first dip glazed mug this week- Wendy_.

I'll find out the mug results in a week or so, but here is my dip glaze results.

Again the #1 and #2 represents one dipping and two. The first is the (Northcote Pottery Italian Green) and you can see that there is a colour difference.
The darker colour on the right(#2) is what the sample looks like and the mug i glazed-with three coats-only shows that in patches. You can't tell by the photo but it has crazed and it is not supposed to do that. It still doesn't explain why the mug cracked.

The second glaze test shows a colour (Italian Blue)i thought was awesome, again #1 and #2 represents dipping results, and yet there is not much difference between the two.


The darker colour you can see at the bottom is a result of the the glaze settling as it dries and is obviously thicker but, to me is still the same colour.(It is a crackle effect).


I did my first test/drip glaze, on a mug, this week in this colour and will show the results when i can.
