Making a Dependable Shelf System
Creating massive, completed glasswork that’s flat, uniform, and effectively annealed is extremely dependent upon having a dependable shelf system. A really perfect shelf system for a big kiln will need to have a steady, seamless floor and be stage, steady, easy, sturdy, flat and capable of switch warmth uniformly. With this TechNote, we suggest one such shelf system and the data wanted to arrange it.
You will discover that making ready this shelf system shouldn’t be tough, however it’s process-intensive and would require a number of days. Taking your time, with out dashing or reducing corners, will show you how to to ascertain a dependable firing floor that, with correct care, will final for a few years.
The three main steps in making ready the shelf system are: leveling the kiln ground in its working location, establishing a mullite subshelf system, and making ready a fiberboard shelf.
Step 1: Leveling the Kiln in its Working Location
Ideally, it is possible for you to to place the kiln in a stage working location.
As soon as the kiln is positioned, you have to to find out how stage its ground is. Do that by inserting a stage on the kiln ground, taking readings back and forth, entrance to again, and nook to nook (Determine 2).
In case your stage is brief, set it on a protracted straightedge to guage a bigger span. If you happen to discover that your kiln ground shouldn’t be stage, you have to to make changes. Some slight leveling may be completed later, by positioning shims below sections of the mullite subshelf (Step 2). But when one facet of the kiln ground is 0.125˝ (3 mm) decrease than the opposite, the kiln itself must be leveled. Typically, for the sake of stability, it’s higher to stage the kiln than to depend on shims.
