The most common glass products; used across alchemy, medicine, and daily life. | | Lenses & Optics | Magnifying lenses, prism pieces, and viewing glasses. May improve Investigation checks, enable long-range viewing, or focus light for use in traps or signals. | | Decorative Works | Statuettes, ornaments, stained glass panels, and art pieces. High monetary and artistic value; popular among nobles and temples. | | Instruments & Components | Glass tubing, alchemical apparatus, lantern globes, and scientific tools. Used to support alchemy, navigation, and engineering. | | Enchanted Glass | Magically attuned objects such as scrying surfaces, one-way mirrors, force-capturing panes, or heat-resistant constructs. | ### Ingredient Types | **Ingredients** | **Description** | | --- | --- | | 🞛 Cullet & Refined Silica | Pre-melted glass chunks (cullet) or refined sand preparations that melt evenly and predictably. Processed from raw silica through filtering, washing, and preliminary melting. | | 🞚 Raw Silica & Minerals | Raw sand, ash, limestone, potash, and metallic oxide pigments (iron for green, cobalt for blue, gold for red). Found in nature, mined, or purchased in bulk from quarriers. | | 🞜 Flux Compounds & Colorants | Precise mineral and chemical blends that lower the glass's melting point, determine clarity, introduce color, and establish magical conductivity in enchanted pieces. Must be measured with care. | ### Creation Cost & Time | **Glassblower Level** | **Creation Slots** | | --- | --- | | Level 0 –<br>Novice | 1 | | Level 1 –<br>Intermediate | 2 | | Level 2 –<br>Advanced | 3 | | Level 3 –<br>Superior | 4 | | Level 4 –<br>Master | 5 | All creation slots are utilized over an 8 hour period. | **Rarity** | **Glassblowing DC** | **Glassblowing Die** | **Slot Cost** | | --- | --- | --- | --- | | Common | 10 | 1d4 | 1 | | Uncommon | 15 | 1d6 | 1 | | Rare | 20 | 1d8 | 2 | | Very Rare | 25 | 1d10 | 3 | | Legendary | 30 | 1d12 | 4 | ### Performing Glassblowing > [!faq]- Glassblowing Creation Example > To produce a ***Lens of Far Sight***, an Uncommon optical instrument that grants advantage on Wisdom (Perception) checks involving sight at distances greater than 60 feet, follow the steps below: > > **1. Gather ingredients** > The ingredients for a Lens of Far Sight are: > 🞜 Clarity Flux Compound > 🞛 Crystal Silica Cullet (Refined) > 🞚 Raw Quartz Sand > For this example, we'll assume Clarity Flux Compound has been purchased from an alchemist. > > **2. Roll a glassblowing check to determine the precision of the lens.** > The DC is equal to... > *the rarity of the creation* — *your glassblower level* — *your [[Abilities#Dexterity|Dexterity]] modifier* (minimum of 0) — *your proficiency bonus* (only if proficient with Glassblower's Tools) > - Upon success, you waste no materials and the lens is ground to specification. > - Upon [[#Failing A Glassblowing Check|failure]], you waste materials and the process takes longer. > > **3. Refine and melt silica.** > In this case, you succeed and now need to prepare ***Crystal Silica Cullet*** from raw quartz sand, which costs 1d6 *portions of Raw Quartz Sand* — *Dexterity modifier* (minimum of 0) per lens. > > **4. Add remaining ingredients.** > All other listed ingredients are consumed at a 1-to-1 ratio unless otherwise stated. > In this example, 1 portion of Clarity Flux Compound is consumed. ### Failing A Glassblowing Check On a failed glassblowing check, roll a *glassblowing die* — *your glassblower level* to see how many ingredients are lost (resulting in a minimum of 1). You must roll separately for both *cullet & refined silica* and *raw silica & minerals*. For time wasted (resulting in a minimum of 1 hour), roll a *glassblowing die* — *your proficiency bonus* (only if you are proficient with Glassblower's Tools). ## Recipes Glassblowing techniques for optics and enchanted glass are closely held by master craftspeople and glassworkers' guilds. Known references include: - *The Furnace and the Pipe* — Foundational techniques for vessels, containers, and decorative work. - *Clarity & Craft: Advanced Glasswork* — Advanced methods for optics, instruments, and enchanted glass construction.
