Rebekah Krieger Posted February 18, 2015 Report Share Posted February 18, 2015 Ok after reading these forums forever I finally placed my order with us pigment. ( will drive to pick it up) (I couldn't find talc on the website?) This is the list I gathered from all of the discussions about starting to mix glaze 50# G200 Feldspar 50#Ferro frit 3134 50# Epk 50# silica (325 Mesh) 50# Whiting 10# Kona F4 10# Dolomite 5# Spodumene 5# Bentonite 5# Superpax 3# Ferro frit 3124 3# ferro frit 3110 Colorants include 5# Rutile (light) 1# cobalt carbonate 5# Red iron oxide (high purity i believe is the common one?) 2# crome Oxide 2# copper carbonate These stains looked yummy to me so I added them on my own to the list: 1 # encapsulated red stain 50779 1# pink stain 6020 1# Green stain 6263 I fire ^6 oxidation so hopefully I didn't order something that I cannot use. Do my amounts look right to you? I am not sure if I am ordering enough cobalt carbonate because i use a lot of blue oxide wash already and hope to make my own blue wash/underglaze. opps I forgot to add- I already have 50# of Gersley Borate and 35# Nepheline sy Link to comment Share on other sites More sharing options...
neilestrick Posted February 18, 2015 Report Share Posted February 18, 2015 Looks like a good start! You might find you need zinc at some point. I'm heading down there tomorrow morning to pick up an order. If it's a shorter drive for you to come to my place I'd be happy to pick up yours, too.

Rebekah Krieger Posted February 18, 2015 Author Report Share Posted February 18, 2015 He needs to send me the bill so I can confirm my payment- but if he gets it to me today that would be very nice of you to pick up for me neil. Plus it's a great excuse to see you. Maybe I could watch you throw a pot or two? Link to comment Share on other sites More sharing options...
High Bridge Pottery Posted February 18, 2015 Report Share Posted February 18, 2015 All look like good amounts to me, I like dolomite so I buy lots of that. That is kinda talc anyway. You will find the cobalt will last ages if only using 1-5% total. Link to comment Share on other sites More sharing options...
oldlady Posted February 18, 2015 Report Share Posted February 18, 2015 HOORAY! now you can have fun! cobalt is very strong, anything over 2% is VERY blue. it will last a long time. adding tin oxide will pale the blue a little. i do not see tin in your order but superpax will do it. where and when did you get the gerstley borate? what do you plan to do with the chrome? make sure you get the msds on everything. how lucky to be close to neil!

Rebekah Krieger Posted February 18, 2015 Author Report Share Posted February 18, 2015 I will look for tin- thank you for the tip! yeah Neil's studio is less than 2 hrs from me. Us pigment is more like 2.5-3 hrs from me I believe. Link to comment Share on other sites More sharing options...
Mark C. Posted February 18, 2015 Report Share Posted February 18, 2015 Talc and maybe a small amount of tin Ox. Mark Link to comment Share on other sites More sharing options...
neilestrick Posted February 18, 2015 Report Share Posted February 18, 2015 I rarely use talc. Most every recipe I have that calls for it also calls for whiting, so I just reformulate to use dolomite. Link to comment Share on other sites More sharing options...
C.Banks Posted February 18, 2015 Report Share Posted February 18, 2015 Titanium dioxide is fun. Black iron oxide is easier to deal with. *Chrome oxide is a bit of a bugbear for me. I know there are nice results but I have avoided using it partially because our kiln was never vented and I just didn't want to deal with it flashing or leaching or ... I just had lots more stable/less toxic things to explore. Link to comment Share on other sites More sharing options...
Rebekah Krieger Posted February 18, 2015 Author Report Share Posted February 18, 2015 a good friend (alabama) sent me some black iron oxide. I am looking forward to experimenting with it Link to comment Share on other sites More sharing options...

C.Banks Posted February 18, 2015 Report Share Posted February 18, 2015 Black iron oxide is easier to deal with. How so? just that the black doesn't need everything it touches to be quarantined quite so severely Link to comment Share on other sites More sharing options...
neilestrick Posted February 18, 2015 Report Share Posted February 18, 2015 Black iron oxide is easier to deal with. How so? just that the black doesn't need everything it touches to be quarantined quite so severely Ah, yes, red iron oxide is a mess. Unfortunately, most recipes call for red.

Crusty Posted February 18, 2015 Report Share Posted February 18, 2015 Yay, Awesome!!! Let the fun begin, again... The only thing I can possibly say that may help you, when you make your test tiles make them big enough to see what the glaze will do... I made my first ones about 1/2'' wide by 3'' tall and they gave me a idea of what It looked like but bigger tiles like 3'' tall by 3'' wide seem to be better and easier to "read" ... Happy for ya ...

oldlady Posted February 18, 2015 Report Share Posted February 18, 2015 you have the essentials, a sieve and buckets, test tiles and a notebook, way to keep glaze out of your drains, containers with lids for all your new ingredients, scoops from walmart pet department and a scale. a 60 mesh sieve is good enough. unless you want to be a superstar. a soft rubber rib pushes ingredients through the sieve with MUCH less work than a brush. no need to spend extra time making it, you want to use it. if you need a lightweight container for weighing ingredients, the cover for a cake works great. supermarket bakeries have stacks of them and if you ask nicely you will probably get a big one free. the ones with simple shapes, not scallops work best. mark the weight of the container on the outside and add that amount to each measurement. don't forget a bunch of containers for glaze and a sharpie to put the name and date you make it. a can of hairspray and a cotton ball will take the sharpie marks off if you need to. ENJOY! Link to comment Share on other sites More sharing options...
Marcia Selsor Posted February 18, 2015 Report Share Posted February 18, 2015 I agree the list looks good. When you are getting into it, the tin, and talc, titanium and maybe strontium to substitute for barium. Enjoy the testing, mixing and blending and tweaking.

rayaldridge Posted February 19, 2015 Report Share Posted February 19, 2015 One thing I do when mixing large amounts of glaze was to tare (compensate) the triple beam for the large container I put on the tray of the balance to hold more ingredients than would fit on the plate. A plastic ice cream tub or other light container holds a lot, and I compensate for its weight by using a bit of wire solder on one of the tare knobs at the pointer end of the triple beam. It's easier than remembering to add in the weight of the conntainer when measuring. Link to comment Share on other sites More sharing options...
Rebekah Krieger Posted February 19, 2015 Author Report Share Posted February 19, 2015 thanks for all the tips! I did end up ordering some tin and a little talc. (he put .75 worth on the order, so I have no idea what it will be. The item is not on the website) Link to comment Share on other sites More sharing options...
Marcia Selsor Posted February 19, 2015 Report Share Posted February 19, 2015 I have a plastic scoop for my triple beam with a counter weight. I can mix 5 gallon buckets but sometimes have to do large quantities in repeatedly weighing if the scoop won't hold the amount. Not problem. Just keep notes or a tally as you weigh out the ingredients. Always add the dry ingredients to water. it is easier to mix. Marcia Link to comment Share on other sites More sharing options...
Dick White Posted February 19, 2015 Report Share Posted February 19, 2015 Be aware that the G200 listed on their website is actually G200HP. That's the high potassium product, different from the original G200. If you are using recipes based on the old G200, you may need to adjust for the higher flux in the G200HP or mix the G200HP 70:30 with the Minspar200/Kona F4. If you are using glaze calculation software, be sure to use the HP material in your calculations. Link to comment Share on other sites More sharing options...
kswan Posted February 19, 2015 Report Share Posted February 19, 2015 Hi Rebekah, I am ready to begin mixing my own glazes as well, and you are giving me inspiration to just do it! I actually took an introductory glaze mixing class at Baltimore Clayworks and it was incredibly helpful. I have an electric kiln at my home that I've used to bisque, but I'm scared to glaze fire for some reason, thinking of all that I could do wrong. I think it's like looking down off of a high dive board and not wanting to take that first step... Okay, first step for today is to make some cone packs using cones 5, 6, and 7... here I go!

Callie Beller Diesel Posted February 19, 2015 Report Share Posted February 19, 2015 Other handy hardware: Measuring cups and spoons Wooden spoons and rubber scrapers in lots of sizes. wire whisk from a restaurant supply place (breaks up a settled glaze better than a drill with a paint mixer) Cheap house paint brush works to push wet glaze through a sieve quite nicely Red Solo cups hold a test batch of 100g Link to comment Share on other sites More sharing options...
Cavy Fire Studios Posted February 19, 2015 Report Share Posted February 19, 2015 Be sure to mix dolomite separately with water and a food mixer, then add last. That stuff clumps like the dickens and is a nightmare to just mix with the other stuff at once. Makes beautiful glaze, though! Link to comment Share on other sites More sharing options...
High Bridge Pottery Posted February 19, 2015 Report Share Posted February 19, 2015 Sure you mean dolomite? I have never had that problem with mine. Link to comment Share on other sites More sharing options...
Cavy Fire Studios Posted February 19, 2015 Report Share Posted February 19, 2015 Really?! Oh man, that crap from Seattle Pottery clumped as bad...OH WAIT, HAAAA BENTONITE THAT'S what I mean!
