The Glazier's Bench is used to make various glass products, such as Glass Rods and Sheet Glass. It runs on Charcoal.

Consult the Glass Making Guide or the section below (needs consolidation) for detailed strategies for using a Glazier's Bench.

• 200 Firebricks
• 400 Bricks
• 1200 Sand

Built in a Compound. Uses 11x17 cells.

Types of Glass

A Glazier's Bench has a reservoir that can contain up to 50 deben of molten glass. It must contain at least 20 in order to craft an item from that glass, regardless of how much the item will actually consume. This means that 19 deben of glass will never be used (This portion is an offering to the Gods). Fortunately, unused molten glass normally stays in the bench between uses, even after cooling, so it is not necessary to fill the reservoir from scratch every time.

An individual bench can only contain one type of glass (soda, normal, or jewel) at a time. If you want to use a bench for a different type of glass, you must deliberately empty the reservoir and start over. Since this is so wasteful, it's generally more economical to build an additional Glazier's Bench for the new glass type instead.

Glass Type	Melting Point	Working Temp	Ingredients
Soda Glass	3200°	1600–2400°	1 Lime, 2 Soda, 10 Sand
Normal Glass	3200°	1600–2400°	1 Lime, 2 Potash, 10 Sand
Jewel Glass	4400°	1600–2400°	1 Lime, 2 Potash, 10 White Sand

Using a Glazier's Bench (more detail)

Glazier's Benches use charcoal as fuel, and in order to melt and shape glass the bench must be heated by adding charcoal. While using the bench, the window will display the current temperature, as well as options to add 2, 6, or 12 charcoal.

Adding charcoal causes the temperature to increase over a period of about a minute -- the more charcoal added, the greater the increase. This is followed by another minute or so where the temperature stays constant, followed by a gradual cooling.

If charcoal is added while the bench is still in the "heating-up" phase from the last charcoal addition, this will trigger a dramatic spike in temperature. This can be a useful way to heat the bench quickly to its desired temperature. However, it is disastrous if it happens while creating an item (when the temperature must be kept within a certain range), as the spike in temperature will almost definitely ruin the item. Keeping the bench's temperature constant demands careful timing between charcoal additions.

Left alone, a bench will eventually begin cooling until its temperature returns to zero. It is not possible to speed up this cooling process. Items made on a bench cannot be taken out until the bench completely cools.

Melted Glass A Glazier's Bench has a reservoir that can contain up to 50 deben of molten glass. It must contain at least 20 in order to craft an item from that glass, regardless of how much the item will actually consume. This means that 19 deben of glass will never be used (The Gods portion). Fortunately, unused molten glass normally stays in the bench between uses, even after cooling, so it is not necessary to fill the reservoir from scratch every time.

An individual bench can only contain one type of glass (soda, normal, or fine) at a time. If you want to use a bench for a different type of glass, you must deliberately empty the reservoir and start over. Since this is so wasteful, it's generally more economical to build an additional Glazier's Bench for the new glass type instead.

Glass Products

There are three types of glass. One of these combinations is heated to high temperature to produce melted glass of the desired type. The melted glass can later be formed to the various end products. It takes 1 deben of glass to create 1 item, except where noted otherwise.

Items that can be produced using soda glass

• Glass Rod takes 60 Seconds
• Glass Pipe takes 90 Seconds
• Glass Blade takes 120 Seconds

Items that can be produced using normal glass

• Glass Rod takes 60 Seconds
• Glass Pipe takes 90 Seconds
• Glass Jar takes 90 Seconds
• Empty Wine Bottles take 90 Seconds (Makes 12 from 1 glass)
• Sheet Glass takes 120 Seconds (Success also depends on the Sheet Glass Fabrication skill)
• Glass Torch takes 180 Seconds (Requires 5 glass)

Items that can be produced using jewel glass

• Fine Glass Rod Takes 90 Seconds
• Fine Glass Pipe Takes 90 Seconds

Making a Mirror

A mirror is made in any glazier's bench regardless of the amount or type of glass. The bench has to be heated above 5000 degrees. To make a mirror you must have 200 Silver Powder and 1 Sheet Glass in your inventory. Sheet glasses in the bench do not count so you have to let the bench cooldown and take the sheet glass out before making a mirror.

Comments

Various glass products can be placed in a Glory Hole, and converted to advanced resources such as thermometers.

More discussion and operation details may be found in the Glass Making Guide.

Pollution

Using this building will cause soot pollution to occur in roughly a 50 coord radius. Running controlled tests at an isolated compound, after running 46 debens of glass through (20 sheet glass, 26 glass jars on 2 benches), the soot level around the compound went from 0 to 6 right as the benches were cooling. Any area effected by soot will cause flax to yield nothing when harvested.
