Typically made with sand from the Dreamscape, dreamglass can become any shape or substance that the craftsman can imagine. A master craftsman can then imbue a particular magical effect into the object using only a deep desire, either of the craftsman herself or another person.
Making Dreamglass
To make dreamglass, a craftsman must first gather at least an ounce of sand from the Dreamscape. This sand is sometimes called sleep sand because of its ability to put someone to sleep if it gets into their eyes. Once it is heated above 2000 degrees, however, sleep sand turns into a liquid and loses any defined magical properties. Instead, the liquid begins to shift color, texture, and size rapidly.
At this stage, it is extremely important that only the liquid is only exposed to the craftsman until it has taken its stable form. Any other person who is within 20 feet of the liquid may cause the dreamglass to absorb their thoughts in addition to the craftsman's, which will result in an undefined form.
To finalize the form, the craftsman uses a traditional glass blowing pipe to gather a glob of the liquid sleep sand and moves it carefully away from the remaining liquid. It is important that the craftsman doesn't start thinking of any distinct form until she has separated the material she intends to work with or the entire batch of sleep sand liquid may settle into a half-formed item, severely limiting its future potential.
Once the craftsman has her working material, however, the process continues much the same as in traditional glass blowing, with the craftsman rolling the glass on the marver, blowing it to give it form, and reheating it periodically to maintain its malleability until it reaches its final form. The final form is dictated by whatever the craftsman most clearly imagined while she was blowing the glass.
Magical Effects
Dreamglass Items
Unlike regular glass, a dreamglass item in its final form cannot be reheated and made thought-receptive again. Instead, the dreamglass item will behave almost identically to whatever substance the craftsman was imagining. For example, if a dreamglass item has taken the form of wood, then reheating it will only cause it to burn to ashes.
The one exception to this is that dreamglass items are susceptible to a phenomenon called "thought erosion." Even when the item is in its stable form, it still absorbs a small amount of the thoughts of those around it. Therefore, a dream glass item that is exposed to people will very slowly begin to lose its form over hundreds of years. Edges become less defined, corners become rounded, and colors dull. In advanced cases of thought erosion, the item appears like nothing more than a gray lump of undefined material.
Some experiments with ancient dreamglass items have shown that it can be displayed for public viewing without erosion if it is in a room by itself and surrounded by pictures of the item itself. This makes the thoughts of the visitors uniformly focused on the proper form of the item, thus reinforcing rather than eroding it.
