D&L Art Glass Supply

What D&L Art Glass Supply does

D&L Art Glass Supply is a privately held specialty distributor and retailer of art glass, craft, and jewelry supplies, founded in 1974 and headquartered in Denver, Colorado. The company operates from a 42,000-square-foot warehouse that stocks over 18,000 SKUs across categories including sheet glass (5,000+ varieties from 25+ manufacturers such as Bullseye, Spectrum, Oceanside, Wissmach, Kokomo, and Youghiogheny), kilns, grinders, glass cutters, coldworking equipment, lampworking glass and torches, mosaic supplies, jewelry findings, metals and frames, and soldering chemicals. The business is led by founder Leslie L. Silverman as Owner & President and has been continuously operating for over 50 years.

The company generates revenue through four streams: retail product sales via its 24/7 e-commerce website (dlartglass.com), physical warehouse/showroom sales in Denver, a structured wholesale program requiring $500 minimum opening orders and $500 annual purchase minimums (with exemptions for schools and certified art educators), and education revenue from in-person classes plus equipment rental at its 1,400-square-foot Learning Center. Distribution covers the contiguous United States via USPS, UPS, and FedEx, with international shipping available. Marketing channels include organic and paid social media (Facebook, Instagram, Pinterest, YouTube, X), email newsletters, downloadable PDF catalogs, search-engine-optimized product pages, and the annual Summer Glass Bash community event in Denver.

The business model is a hybrid B2C/B2B specialty distribution operation, differentiated primarily by inventory scale, multi-discipline domain expertise, and an integrated education ecosystem. There are no public financials, no disclosed funding, no institutional investors, and no recent M&A activity referenced in the available data; ownership appears to remain founder-controlled after 50+ years.

Scale indicators6 records

Recent moves3 records

Expansion highlights4 records

Direct peers

• Sundance Art Glass: Sundance Art Glass is an online specialty retailer of stained glass and fusing supplies with comparable assortment breadth across glass, tools, and kilns. Targets the same stained glass and kiln-forming hobbyist segments.
• Delphi Glass: Delphi Glass is a leading direct competitor in stained glass and art glass supplies, offering similar sheet glass, tools, kilns, and classes. Closest like-for-like specialty retailer serving the same hobbyist and studio customer base as D&L.

Emerging players

• Olympic Color Rods: Olympic Color Rods is a specialty supplier focused on glass rods and tubes for lampworking and beadmaking. Overlaps with D&L's lampworking category but with narrower scope and a manufacturer-leaning model.

Others

• Glass Alchemy: Glass Alchemy is a manufacturer of colored borosilicate glass rods for lampworking, stocked by D&L. Adjacent as a supplier and a partial substitute via its own DTC channels for specialty lampworking rods.
• Bullseye Glass Co. Bullseye is a major art glass manufacturer and key D&L supplier. Comparable because it sells fusible glass directly online, competing partially with D&L's retail assortment while also being a partner brand.
• Northstar Glassworks: Northstar is a borosilicate glass rod manufacturer featured in D&L's lampworking catalog. Comparable as an upstream partner whose direct-to-consumer offering overlaps with D&L's specialty assortment.
• Oceanside Glass & Tile: Oceanside is a manufacturer of art glass and tile that supplies D&L. Comparable as a key upstream partner and direct-to-consumer competitor for overlapping SKUs (sheet glass, fusible glass, tesserae).

Broad incumbents

• Amazon: Amazon is the dominant general e-commerce marketplace that lists many of the same grinders, cutters, kilns, and consumables D&L sells. Indirect peer due to price transparency and convenience, not a specialty peer in art glass curation.
• Michaels Companies: Michaels is the largest US specialty craft retailer with broad assortment overlap in stained glass, mosaics, and jewelry-making. Much larger scale but materially shallower specialization in art glass.
• Blick Art Materials (Dick Blick): Blick is the largest broad-line art supplies retailer in the US with significant overlap in glass, jewelry findings, and craft tools. Broader assortment but less specialized depth in art glass compared to D&L.
