food warmers to dry out plaster molds
I am new to glass but not to scavenging. I recently scored a large food warmer from a cafeteria and am using it to dry out plaster/silica molds for kiln casting. This thing is an insulated stainless steel warmer that is bigger than a refrigerator, has adjustable rack shelves, a timer, and recirculates air at 168 degrees. It works great. You folks probably already know all about these food warmers but just in case...
I also scored a large gas fired hamburger grill (24"X36") that I will use as my heat source for a lost wax steam out system. Sorry if this is all old news.

I think you need to devise a way to let the moisture vent and escape to optimize the unit.
The traditional steamer is made with a pressure cooker. You direct the steal out of the top to a flexible tube and melt out the wax with it.
I would keep the grill and cook burgers. I just got a 12" x 30" grill as part of a commercial range in my kitchen, under a hood, and I love it.

A book over in spab's place.rosanna gusler wrote:so, db. whatcha gloating about? rosanna
Also am gloating because I'm on vacation for a week. Get to work on my Christmas suncatchers, carve my pumpkins for halloween (my primary talent and real reason I have been allowed to survive and not be struck down by lightning) and sleep in. No staring at a damn computer monitor all day....well, not all day.

Hi all, computer problems and a little travel have kept me from responding. The tool gloat was not my intention. I figured that all restaurants and cafeterias have these things and that there can't be much of a resale market, therefore they could be had cheaply. I find that it works very well and just wanted to share the information. I appreciate Bert's recommendation that I vent the unit to maximize the drying. Do you think just some holes at the door top will allow proper venting?
As far as the grill as a heat source for a steam out unit, I have used the oil drum steam out as described in Henry Halem's book and have found it very effective. The molds are getting larger thus the need for a larger steam out unit.
I am very new to cast glass. I have kiln cast several pieces in a couple of kilns and am still waiting to open the lid. The molds were 6" thick so I selected an annealing schedule based on 6" thick glass. I am using Bullseye cullet and they recommended a 21 day anneal, Graham Stone would do it in 15 days and Libensky would do the same in about 9 days.
I am certainly confused. I

I am certainly confused. I choose the longer Bullseye schedule but even without experience feel this is conservative. I am a sculptor and figure that my work will probably just get thicker. I would appreciate any suggestions on the schedules.
Thanks, Ted Metz
