A fuser working in COE 90 needs Bullseye sheet glass, frits, and a kiln schedule for a 6 inch pendant. A stained glass artist wants Spectrum 96 wispy clear and a Tiffany style copper foil pack for a 2 foot panel due in three weeks. A lampworker hunts Effetre soft glass rods in turquoise and ivory for marbles and beads, fired in a Carlisle Mini CC. A beginner asks if Bullseye and Spectrum can be mixed in the same fusing project. Each conversation needs technique aware answers grounded in COE math and tested compatibility.

SleekAI maps COE rating, color family, opacity (transparent, opal, iridescent, dichroic), tested compatibility status, sheet size, and technique suitability (fusing, stained, lampwork) as product attributes. Kiln products carry chamber size, max temperature, and recommended schedules for the COE families they support. When a customer asks for COE 90 sheet glass in deep red transparent, the bot reads _coe, _color, and _opacity and returns only Bullseye products that fuse together cleanly.

Generic chat widgets cannot do this. They mix COE 90 with COE 96, ignore the fact that Bullseye Tested Compatible status matters for fusing, and recommend kiln schedules that crack the glass on cooling. SleekAI treats COE and tested compatibility as first class attributes and returns recommendations no fuser would have to second guess.

Art glass spans three distinct disciplines (fusing, stained glass, and lampworking) that share some materials but follow very different rules. Mix them up and projects crack, beads explode in the kiln, or panels never come out of cold soldering. COE compatibility is the most common failure point for beginners and the most frustrating to recover from because the work might look fine until cooling, then fall apart.

SleekAI handles this depth natively. The bot reads COE, tested compatibility, opacity, and technique suitability as first class attributes. A fuser asking for red transparent on a clear base gets Bullseye COE 90 products that are TC labeled together.

A stained glass artist gets Spectrum or Wissmach without confusing COE rules. A lampworker gets Effetre soft glass with the right torch fuel context. Beginners get explicit warnings when they try to cross COE families.

Studios that adopt this kind of tool see fewer cracked projects, more confident beginners, and stronger advanced customer relationships because the chat respects the technical depth of the medium. The bot extends the studio's expertise to the website without watering it down for a general audience.
