Harrach Vaseline Opalescent Vases and Jug

Two vases and a jug demonstrating interesting opalescent patterns, including stripes and lattice work. All have flowers but one of them has a moulded or pressed white version with yellow centre. The two larger examples have broken pontils but the smaller doesn't - no pontil at all. Manufactured by Harrach around the turn of the 20th century? Unfortunately, the two taller vases have some damage to the feet. However, collectors have to accept this. The vase with the ruffled blue top reminds me of a triffid! Height 24 cms while the jug is 20 cms. The jug absolutely glows under a black light.
