Can I use plaster in my ceramic bisque molds without ruining the molds or having the plaster stick to the molds?
No, sorry. Plaster of Paris expands and the plaster will stick to your molds and is impossible to remove. It will also remove some of the fine detailing of your mold. An alternative is to put the plaster on one of your finished pieces, half at a time to get a mold of the piece. This will give you a new mold of the piece without destroying your original mold.
Does 1930 lath and plaster have asbestos?
Lath and plaster construction from the 1930s might contain asbestos, or it might not. It could have animal hair mixed into the plaster, instead. The only way to know whether a particular installation contains asbestos is to have a sample collected by a qualified technician and analysed by a qualified laboratory.
How can you tell if your walls are plaster or sheetrock-drywall?
* Try to stick a push-pin or ice pick into it. Sheetrock/drywall is soft and the point should go in easily. Plaster is hard -- it will be hard to push the point in and the plaster will tend to crumble.* Go into the attic and look under the insulation. Drywall is smooth. Lath is very rough. It's applied to strips of wood with gaps between. The plaster is squished between the strips to form "keys" that hold the plaster to the wall. See links. * Remove an electrical outlet cover and look at the edges of the exposed wall. You may be able to see the ends of the lath strips.
Is there a way to skim coat or tile over an old lath and plaster ceiling?
lath and mortar walls and ceilings have a greater flexibility than standard plaster. If you do plaster over it you firstly need to be very confident that the old mortar is sound and fully adhered to the lath. You would also have to seal the ceiling well to stop the water in the plaster from literally being sucked out of the plaster. Regarding tiles. If you are thing about ceramic tile then NO!. The weight of the tiles would pull the mortar from the lath with great ease. It is defiantly better to either plasterboard directly to the old ceiling and using dry wall screws NOT NAILS screw directly to the joist not the late you can then put a good scrim tale over the joints and plaster accordingly. The very best option however, is ...............drop the old ceiling, re-board and plaster

Is plinth wall a load bearing wall?
Lath and plaster is just an old type of wall finish. Like drywall is a wall finish. What the wall is constructed of underneath the lath and plaster and where it is placed in the building determine if it is load bearing or not. A lath and plaster wall could be load bearing or it might not be. IF it is an outside wall, it most certainly is load bearing. other than that, the best way to figure it out is to have a structural engineer tell you wether it is or not. Even if it is load bearing it may be possible to remove it if a beam is put up in place of the wall. Really, the best and safest way to decide is to have a engineer look at it.

Why does ceramic slip stick to plaster mold?
The plaster mold is very, very dry. When you pour, the clay slip is mostly water and the plaster mold sucks up the moisture quickly, creating a coating inside the mold. It's like pouring gravy onto a sponge...the water is absorbed, but the solids stay on top of the sponge if you leave it long enough. It's the same way with a plaster mold..it's a sponge. That's the reason you watch the pour opening and pour out the excess when it is the thickness you need. The plaster will continue to absorb until the clay pulls away from the mold naturally, yet it is still green.
