Finding heavyweight silk
Heavyweight is a constraint on silk, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Silk is filed here as protein fibre. One reason to open it is useful for overlays, linings and elevated ready-to-wear. One reason to sample is sheer constructions need opacity planning.
Judge heavyweight together with construction. Heavier cloths can overheat in warm climates or feel stiff if the silhouette wants fluidity.
What not to assume
A heavyweight filter does not certify the cloth. dresses, blouses, scarves are common places buyers test silk, and some of those garments will reject this attribute.
