In Topic: Ketchup Red Glaze

Today, 12:58 PM

i think the name is a problem.  picturing ketchup makes me think of the fresh-out-of-the-bottle red.  what really comes out is dried up from yesterday's picnic redbrown.


In Topic: Brent Foot Pedal--Ugh.

Today, 12:52 PM

it sounds as though you bought a brent wheel through amaco.  amaco's response was unsatisfactory.  it might be time to talk directly to brent.  tell them to read this entire thread.

that is ok, doris, unless you are responding to a cry for help from the middle of the river.

bars are more consistent simply because you cannot put them in differently each time.  they work very well.


In Topic: Using Fresh Leaves For Making Molds

Yesterday, 09:10 PM

chilly is right, working with plaster is fairly easy once you do the first one.  my use of molds is different.

 

 i find interesting leaves with a great shape and veining.  if the raw leaf works, vein side down, as a flat tray, i might put a number of them on a slab of raku clay and make a mold.  designing the most pleasing layout is the fun part.  pressing the leaves into the raku clay is the work. after it is fired to cone 04, it is ready for use. 

 

to use the mold, i roll out a slab of clay and press it very firmly into the fired raku clay mold.  this picks up the shape and veining and whatever i add to the original mold, like a dragonfly. (people seem to buy anything with a dragonfly on it.)   the mold might be fairly large and i can use any part of it for any shape or size tray or plate.  so all of them, seen when finished, look similar but they are not identical.  spraying the glaze makes them different also.

 

a couple of tips if you want to try this.  raku clay is more forgiving than my regular clay when it comes to making the original mold.  my usual work is thinner than a lot of potters choose to work but it is a very strong stoneware and how thick is a piece of bone china, anyway?  i do not aim to make a thick, heavy, STONEware platter, tray or whatever. the mold is thicker and needs to be, hence, raku clay.  

 

put some foam rubber under it when rolling a slab into it.  use a pony roller and work the slab into the mold.  you only get one chance to get it firmly shaped.  if it lifts up off the mold, you are done.  no second chances until you roll out a new slab.  sometimes a very dry mold will make the clay slab pull out too early, if so, a slight dampening will help keep the slab down.

 

without much of an investment in time or trouble, you might find you like working this way as much as i do.  :unsure:
