    Stamping Pottery

    When throwing, incise a thin shallow line to use as a guide. This line can then be rubbed out after stamping, if need be.
  2. Nothing happens to the join when the sugar burns out. I have used spooze several times. Always successfully. But the pieces MUST be bone dry. Have used it reattach the goblet cup to the stem. Then after it setup handled the goblet normally as if it had never broken off.
  3. A lesson learned... The last weekend in February was the last time I touched a kiln load of pots ready for single-fire glazing. Around June 6th is when I started to glaze. I pour the liners on mugs and pitchers. Then begin to spray the exteriors. 2 days after pouring a thin crack appeared in 2 pieces. I looked in the Hamer book and found out the crack is from readsorption. We had a very rainy spring with periods of extreme dry weather. The pottery shop had the windows open during this time. I took me about 2 weeks to glaze the pieces and 29 test glazes. Kiln was fired June 17. I have always d processed the pottery this way. Throw a kiln load, then when all pieces dry, begin to pour and spray. I have never waited this long between the making and the glazing. Lost 5 pieces due to this readsorption. Never in my wildest dreams, in order to make decent pots, did I consider being a physicist, chemist, geologist, and any other ...ist I may have left out. Picture of the hairline crack and a picture of the survivors. At least all were not lost. Also, I finally figured out how to properly load the kiln. This firing had the most even firing across the whole kiln. All cone 6 were bent exactly the same.
  4. If you have access to the May/June 2018 edition of Pottery Making Illustrated, this very piece is demonstrated on pp. 10-11 by Sumi von Dassow. It is called a Microwave Baker.
  5. It is the cover glaze over the iron saturate glaze that must be put on extremely thick. "...apply to an almost unbelievable thickness of 1/8 - 1/4 inch (3-6mm)." John Britt from his ^6 glaze book. I spray the iron glaze then pour the cover glaze. The cover glaze is mixed to a specific gravity of 1.65 - 1.70, very thick. You must be brave to apply this much glaze. It works. Some of the globules that are created and dangling will come off if handled roughly. I had one on the bottom of a handle. I touched it and it broke off. It was hollow inside.

    Which cone I need

    Laguna's website has firing and other information for each of the clays they make.
  7. Not a back-fill person. I tried it on a batch of mugs. did the bottom attachment and not the top. It looked good but did not put this process into the workflow. However, after seeing Callie's pic of the white mug, I like that a lot. I make the dogbone handle from a slab, The upper attachment point looks a lot like the white mug pic. Adding the filler sure makes the pot complete, slick, and to me, highly professional looking.

    Posting equipment pics

    Linda A You will be able to upload more pics at one time if you decrease the size of the pics first. If you have MicroSoft Office Picture Manager, click on Edit Picture, then click on Compress pictures from the menu on the Right side of the screen. Choose Documents then OK. Be sure to save the newly compressed pic in a folder of your choice. Then upload it. Choosing Documents will shrink the pic to under 300 KB. If you have another picture manager software or viewer you can use the ReSize option where you can use either preset resizing or use the pixels settings to shrink the pic.

    Latest fails as of 05.31.18

    As a beginner, when you make something functional, use the piece. This will tell you how comfortable the handle is. It will tell you if the lip dribbles. Does the bowl feel good when mixing something in it. Does the glaze on the outer surface of a bowl have "sticktion". What I mean is can plastic wrap stick to the pot so that it can be utilized as storage in the fridge or elsewhere. With new forms you need to use them to discover their strengths or weaknesses. When you attach the handle make sure you have a 1/4 inch gap, at the greenware stage, between your fingers and the mug. Also, make your handles at least 1 inch wide at the top then you can taper them down. Small round handles are hard to hold. Keep on keeping on...
  10. So you cut the, I'll call it a" scorpion" , out of the vinyl flooring then you glued it to another piece of vinyl flooring?

    DIY spray booth with waterfall

    Thanks Fred for the video! OldLady my spray booth uses a shower base and plastic cardboard for the walls and ceiling. It is NOT waterfall but only takes 15 minutes to clean using a garden hose and a large bucket situated under the drain hole in the shower base. The bucket gets heavy with water and I use a dolly to move it outside to empty. Total about $160. This amount included a 50 cfm fan. This fan was woefully underpowered. Found a 160 cfm fan. This fan cost about as much as all the other materials combined! I think my setup can be converted to waterfall. Need the sump pump and tubing. And would like to see the other 2 parts of Joe's video. He has thought this out pretty good.

    ISO of a perfect matte white dipping glaze...

    Perhaps slow the cooling down in the glaze fire.
  14. Do you back fill handles at the attachment point? If so, is it for aesthetic or structural reasons?

    Any Uses For Them?

    Use an angle grinder to score an 1/8" - 1/4" deep groove in the shelf. Do this on both sides with the grooves opposing each other. Place the shelf on a 2x4 with the part you are cutting off overhanging the edge of the 2x4. Place another 2x4 on top of the shelf on the part you are cutting off, very near the groove. Smack the 2x4 with a hammer. The shelf should break along the score line.
