In Topic: Which Do You Prefer For Joining Process?

Today, 10:44 AM

If you have problems with joins then magic water alone or slip made with magic water or magic water slip made with paper pulp is worth a try. 

 

You are adding sodium (from the sodium silicate plus the soda ash) which is a strong flux which helps fuse the joins together. Also, the silica in the sodium silicate adds a titch more glass former to the join. Sodium silicate is also really sticky stuff which helps the joint bond plus slip made with it dries really hard. It also acts as a defloc and is water soluble so is able to work into the surrounding clay a bit. So in theory the bond is stronger while drying right through to the finished join having more melt and fusing better when fired.

Does anyone know what kind of paper that is??

 

 

I think he uses uncoated mylar. If you google henna cones some people use that or basket cellophane wrap.One source for pre-made cones is: http://www.shophenna.com/  There are nice henna designs on that site also, 

 

 You can also cut up potato chip bags and use that. My sister used to be a chem engineer at Dupont, I have a huge roll of mylar from there, if you would like some just pm me your address and I'll mail you some.

Looks similar to what is done with the Steve Tool.

Sounds like you did a good job with all the work you did on the kiln.

 

I would go with Orton cones any day over the pyrometer. Sounds like you did over-fire if the bar is dark, shiny and beyond slumped.

It shouldn't have been over-fired much at all if you went to 1950, especially if you fired fast, so I would guess your pyrometer isn't accurate.

 

If you stick your tongue on the pots and the pot grabs it a bit then your pots are probably still porous enough to glaze without much trouble. Just don't let your neighbours see you licking your pots. :)
