Need Info On Using Old Plaster

25 January 2015 - 10:32 AM

Is there a way to mix a small amount of plaster to see if it is still good to use for molds ? I have a bag that has been wrapped in plastic, unopened, for 2 years. All I know about plaster involves a complex formula to make a large amount. Seems like someone on this board said something to the effect of.." I'm always mixing up a bit in a cup to make a small sprig or something."
Was that Benzine?

I would appreciate advice on how to tell if the old, but unused bag is still good, it has been kept in heavy plastic bags since it was purchased, and also, HOW TO MIX a small amount to use a little bit now and then, not a big day's project.

Is it too late in the game to get a copy of those?  I think that would be a great way to start the year.

TIA.


Should This Glaze Fire Out Glossy?

20 January 2015 - 11:22 AM

I have been using this glaze for a while now, and rarely it is the satin matte that the recipe describes, but most firings it comes out really glossy.it is well behaved in the bucket and dependable, no running, fires out smoothly, a nice glaze, but not what I want.
The cones are the same every firing and the clay is, also. The Si-Al rating is 4.6-1. any suggestions, the satin is great, the glossy not what I want.

Wax Line For Weird Shaped Pieces?

09 January 2015 - 08:00 AM

Do you have a good technique for getting the wax high enough, but not higher than needed, for large, rather flat, irregularly shaped trays? I have hand built some of these and am trying to get this figured out. I have tried sitting the bisque platter on a damp towel and then waxing 1" higher than the wet mark, or putting the tray on the edge of an eye ball high shelf and marking the spot where it leaves the shelf on the underside in the upward curve. both of these ways seems like guesswork and I am afraid an error will result in the loss of the pieces to sticking to the kiln shelf. For other work, I hot wax very successfully.
How do you do this?

Loop For Hanging Large Platters

04 January 2015 - 10:31 AM

I am looking for a way to add a loop to the bottom of large platters that will stay out of the way of use but be available to hang if the buyer wants to.  These are slab built pieces, so no foot ring to pierce like if it was thrown.  Would a hand built foot ring with a hole in it be strong enough? I have visions of the ring letting go while hanging !!  Would an added loop on the underside that doesn't affect how it sits on a table be enough?
