In Topic: First Time Spraying Glazes...need Some Advice

27 July 2014 - 09:07 PM

Where did you guys find plastic jars that fit the rings on the Critter?  I tried U-Line but they did not know the fittings of the jars they sell. I thought the term Mason Jar would answer the Q, but did not.

I also don't like the idea of glass jars, and I like extras filled and ready to spray before I start the process.

Min, did you take the Critter apart, take off the jar base and put on the rings -lid of the plastic jars you found?  Did not think of doing that.

 

If you take the gun assembly off the mason jar lid it can go on any size jar. I bought mine from Seattle Pottery Supply. They look just like the ones commercial pint glazes come in. (they are a lot lighter than glass jars too, makes it easier on the arm when you are spraying all day)

 

Just remove the mason lid (just a couple set screws) and use that as a template for drilling holes in the plastic jar lid. 2 for the set screws, one for the siphon tube and one for an air hole.

I tried quite a few before settling on the Critter (bottom feeder type). I don't like the glass mason jar that it comes with, replaced them with 1 pint plastic ones. I bought empty 1 pint plastic jars and removed the gun from the mason lid, drilled out the lid from the plastic jar and screwed the gun onto that. No gaskets and no glass.

 

I also like the gravity feed ones with a 0 point 8 mm nozzle but found they needed more maintenance than the Critter. If you do use a gravity feed one I would suggest removing the little filter from inside the gun as it tends to clog up.

 

All the glazes go through a 80 mesh sieve.

I hope I don't come back as a potato bug.

TJR.

 

I hope you don't either, or a echidna.  :P

I think it would still work. If you ran a heat gun over the bits they should melt out. (heat gun on low setting so you don't blow it onto the unwaxed parts)  Running the heat gun over then quickly wiping with a scrap of saran wrap leaves a really slick surface like using hot wax.

 

Not a perfect solution but it would save throwing it out.

Sorry Biglou13, not trying to hijack the thread!

 

Me too Lou!

 

One more thing re pinholes and downfiring. I have started trying a 30 min soak at 125F below top firing temp to see what it does with pinholes. I have one glaze that has a lot of titanium dioxide in it that is prone to pinholes. Haven't done enough testing to have a definitive conclusion but I think it does help a bit. This is a glossy glaze that goes matte if I slow cool it but the new way I'm testing avoids this. It doesn't seem to add a lot of heatwork but it does add some.
